Remote Whispering Applying Time Reversal Acoustics
Description: We are developing new techniques to target an individual in a room and communicate with them without the need for that individual to have any equipment. Time reversal is a sound focusing technique that allows remotely placed loudspeakers to focus sound to a selected point in a room. We use time reversal as the carrier signal to deliver signals to a target location so that the individual at that location can understand the signal but others in the room cannot understand it.

Defect Imaging in Steel Using Time Reversal Nonlinear Acoustics
Description:
We are developing new techniques to locate and characterize cracking in stainless steel structures using ultrasonics. In the United States, spent nuclear fuel is being stored inside stainless steel storage casks. We wish to prevent leaks of these casks by detecting cracks before they penetrate through the walls of the container. We use a sound focusing technique called time reversal to focus energy to inspection points. We then analyze the focus of energy to determine whether that location exhibits nonlinear acoustic behavior, indicative of cracking.
We will be using modifications to the traditional time reversal process to redo some nondestructive evaluation experiments that a recent graduate student did in order to determine whether they improve the ability to detect and locate cracks in steel. Preliminary experiments show this has a high chance of success.

Ultrasonic Time Reversal Focusing in Air
Description:
This project will explore the use of time reversal to focus ultrasonic sound in air to create a high amplitude impulse of energy. We want to explore the limitations of doing this and what amplitudes are possible to achieve. If the sound levels are high enough then we can explore some nonlinear acoustic phenomena that may create audible sound due to known nonlinear acoustic effects. This would create a phantom sound source.

Period Changes in Medium Amplitude delta Scuti Variables
Description:
In general, researchers consider there to be two groups of delta Scuti variables; the High Amplitude delta Scuti (HADS) and the Low Amplitude delta Scuti (LADS). However, the in between realm is interesting. The Medium Amplitide delta Scuti stars seems to show a range of changes in both amplitude and period. This makes them a very interesting group to monitor. Often we participate with astronomers from around the world in taking data for these projects.
We are now adding some computer modeling to try to better understand these changes.

Spectroscopic Survey of Northern Sky delta Scuti Variables
Description: To understand the nature of the delta Scuti variables in the instability strip one needs as much information as possible about the stars. However, an examination of the catalog of delta Scuti variables shows a lack of basic information on many of the group. Of the 247 delta Scuti stars visible in the northern hemisphere we currently have spectra of 242 of them. These need to be reduced to provide estimates of some basic stellar properties like [Fe/H], radial velocity, rotational velocity, and perhaps information on any binary companions.

REU StudentsNeeded Skills: Skills from Phscs 529 useful. If willing you could learn the skills as you go along.

Impact of Cadence on Variable Classifcation by Machine Learning
Description:
This is a project to examine how little data is needed to determine an accurate period in the pulsations of a short period variable star. There are many large survey programs running, or soon to be running, that find new variable stars. Through machine learning they try to classify these objects. However, for short period variables the classifications and periods determined, are found to often be wrong.
We are also examining the impact of space velocity on the measurements, phase jumps in the pulsation curve, and measurement errors.
We do observational work to followup on these new variables and modeling work to show the limits.
This is a program that is currently very active and where students are needed.
Suitable For:
Undergraduate Students

REU StudentsNeeded Skills: There are a wide number of places to join this work, so the skills needed vary greatly. It is possible to start with no previous background. For some work programming skills are required, but the language used is open.

Photometric Reverberation Mapping
Description: Traditional reverberation mapping to estimate AGN black hole masses uses a combination of photometry and spectroscopy to determine the time lag between variations that occur at the accretion disk and then later in the broad line region. With such techniques, there is a need for a large amount of moderate to large telescope time in order to secure the spectroscopic data with an observing cadence suitable for a determination of the time lag. Photometric reverberation mapping uses a single epoch spectroscopic determination of the broad line region velocity and a time lag determination based on photometric observations that include predominantly continuum features or broad line components that can be seen to vary at a later time. This technique is still being tested but hold promise for the determination of black hole masses in the age of several large scale surveys.
Suitable For:
Undergraduate Students
Graduate Students
REU StudentsNeeded Skills: Students are welcome to join this effort if they are willing to work at the West Mountain Observatory to secure the precision observations needed to investigate this interesting technique.

Testing the standard model of active galactic nuclei through automated multicolor broadband CCD imaging
Description: Remote Observatory for Variable Object Research is a 16" RC Optical telescope on a Paramount pier sited near Delta Utah. Operational since 2008, it is used to remotely monitor active galactic nuclei (AGNs) which includes blazars, quasars, Seyfert nuclei and Low Ionization Nuclear Emission Regions, or LINERS. The standard model of AGNs assumes each is a supermassive black hole surrounded by an accretion disk. The disk is fed by a more extensive lowerdensity region surrounding it. The disk brightens and dims as gas falls upon it and as dusty clouds orbiting around it obscure it from our view. Optical variability measures these effects providing data that can be used to model the specific nature of different AGNs.

Laser cooling, ultracold plasmas, laser spectroscopy, biophotonics (experimental)

Ultracold Plasmas
Description:
We are making ultracold plasma by photoionizing lasercooled calcium atoms in a MagnetoOptical Trap (MOT). The trap size is about 1 mm and it holds about 10 million calcium atoms at a temperature of 0.001 K above absolute zero. The ultracold plasma is formed when we shine in two laser pulses that ionize all of the atoms.
The plasma is "strongly coupled", meaning that the average "nearestneighbor" Coulomb energy is orders of magnitude larger than the mean thermal energy of particles in the plasma. A strongly coupled plasma behaves in some ways more like a solid than a gas. One of our major research goals is to understand how strong coupling changes basic processes like recombination and collisional ionization.
We use calcium to create this plasma because the energy level scheme in Ca is favorable for laser cooling and trapping. The blue wavelengths for both Ca and Ca+ are easily generated with standard laser technology. So when plasma is created we can measure the ion temperature and plasma density in a straightforward manner.
Our newest two projects are using lasers to cool the ions in the plasma, and also generating a plasma with both Ca and Yb ions at the same time. This last project will allow us to study the approach to thermal equilibrium in a twotemperature and twomass system.Suitable For:

Effects of Roughness of Reflectance
Description: Simple calculations of optical reflection and transmission from surfaces assume flat surfaces with abrupt interfaces. These assumptions are often sufficiently incorrect to lead to significant errors in computing the optical properties of mirrors and coatings in the extreme ultraviolet.

ZnO thin films
Description: Zinc oxide is a semiconductor that potentially has good optical properties that should allow it to be used to make semiconductor devices such as LEDs and lasers. However, to make such devices you need both “ntype” and “ptype” material. (Ntype has extra electrons compared to what is needing for bonding; ptype has an electron deficit.) ZnO tends to naturally form as ntype and it's traditionally been very hard to make good quality ptype ZnO, but we're working with faculty member David Allred and visiting professor Gary Renlund to develop a new synthesis technique. We've been doing film growth on substrates coated with ZnAs using a sputtering technique, and optical investigations of the resulting material. For that matter, we plan to publish a paper on the ZnAs coating that we’ve produced along the way.

Nanoparticles as temperature sensors
Description: We're working with a mechanical engineering professor (Troy Munro) to use semiconductor nanoparticles as temperature sensors. The wavelengths of light present in the nanoparticles' photoluminescence (aka fluorescence), and the time it takes for the luminescence to be emitted after the electrons have been excited both depend on the temperature. By characterizing the nanoparticles’ photoluminescence spectrum in both wavelength and time as a function of temperature, we hope to be able to use the nanoparticles as noninvasive temperature sensors in e.g. medical applications. For example, one could use the optical emission from nanoparticles injected into tissue to monitor temperatures as focused ultrasound is used to heat up and destroy tumors.

Atomic and magnetic structure investigations of complex materials
Description: One of the first steps toward understanding any given material of interest (a new superconductor, an unusual magnetic material, an energyrelated compound, etc) is determining its atomic and magnetic structure. We utilize beams of xrays, neutrons, and muons at largescale accelerator facilities to do just that. Our primary experimental techniques include atomic and magnetic pair distribution function (PDF) analysis, conventional xray and neutron scattering, and muon spin relaxation/rotation. A few times a year, we visit these types of facilities to collect data, and then we come back home to analyze and make sense of it all. Through this process, we hope to shed light on the origin of the material's properties by gaining a detailed understanding of the local and average atomic and magnetic structure.

We are currently developing open source, pythonbased software tools to analyze experimental data collected from condensed matter experiments using xray, neutron, and muon beams. The software will maximize research effectiveness and enable new methods of analysis not only for our own research group, but also for the wider community of condensed matter physicists using similar types of experimental methods.

Materials simulation: Algorithm development and applications
Description: Our group focuses on computer simulation of materials for the purpose of discovering new materials that have exceptional properties. There are two aspects of the research: 1) developing new approaches, algorithms, and mathematics that can be used in simulation, and 2) applying existing and new approaches to find new materials. Both aspects are challenging and require participating students to move far outside their comfort zone and learn things that won't be part of a regular physics or CS degree.

REU StudentsNeeded Skills: Students must be be motivated to learn and must dependably balance research time with other studies, family responsibilities, etc. Funding is available for all students who so demonstrate.
Few of my successful students in the past had prior knowledge in solid state physics or had abilities such as programming and using Linux/Unix. Such things are nice but exerting the effort to learn is more important.
Students should embrace the opportunity to learn new mathematics, new software engineering practices, to work on a team. Students must be dependable. This is not the group to join if you are just trying to graduate.

Information theory of multiparameter models
Description: Mathematical modeling is a central component of nearly all scientific inquiry. Parsimonious representations of physical systems, together with robust methods for interacting with them, is one of the primary engines of scientific progress. Much of the work in our group involves developing new methods, both theoretical and computational, for improving the predictive performance of complex multiparameter models. Our research explores the mathematical structures that enable predictive modeling. We use information theory, statistics, differential geometry, and topology, as well as relevant physical laws from a variety of fields to better understand data, models, and the relationship between reductionism and emergence.

Computational methods for exploring highdimensional parameter spaces
Description: Modern computers enable large models of complex processes. These models often involve a large number of parameters and a relevant question is often how the model's behavior depends on the parameter values. Because the parameter space is highdimensional, a brute force search will never be possible for models with more than a few parameters. We are developing novel computational methods for efficiently and intelligently exploring these highdimensional parameter spaces. This project uses theoretical insights based on information theory and applies sophisticated techniques in computational differential geometry, automatic differentiation, and topology with highperformance computing. Our goal is to improve algorithms for fitting models to data, performing statistical sampling, and classifying regimes of distinct model behaviors.

Modeling Complex Energy Systems
Description: Models of energy systems involve a large number of heterogeneous components connected in complex networks. Detailed models of these systems constructed from physical first principles are similarly complicated and involve a large number of unknown parameters. In spite of their detail and complexity, models often have limited predictive capability because it is difficult to identify the model, i.e., find accurate values for all of the parameters. Our goals it develop models that are sufficiently complex to capture the rich behavior of real power systems, but simple enough so that all the parameters can be learned from data.

Modeling Complex Biological Systems
Description: Biological systems are rich in the types of behavior they can exhibit. This is enabled through a complex web of components. In the case of development biology, the relevant components are networks of chemical reactions while in neuroscience, it is a combination of electrical and biochemical signals. In both cases, the complex system responds to external stimuli and performs calculations to formulate an appropriate response. The complexity of these systems is overwhelming. New theoretical and computational tools are needed to organize our knowledge of these processes and compress it into a coherent theory. Our research tries to develop minimal models from these "parts lists" in order to summarize and organize our understanding of biological and neurological processes.

Superconducting Materials for next generation particle accelerators
Description: Particle accelerators are are foundational technology in modern science, enabling fundamental research in facilities such as the Large Hadron Collider (LHC), as well as providing some of our best sources of coherent xrays for probing nanoscale structure in materials. The same physical principles underly other technologies such as electron microscopy. Superconducting resonance cavities are the enabling technology that allows subatomic particles to be accelerated to near light speeds. In collaboration with researchers at the Center for Bright Beams (cbb.cornell.edu), we are working to better understand materials properties of superconductors in order to lay the foundation for the next generation of particle accelerators. Our work uses high performance computing to solve equations that describe how specific materials respond to applied magnetic fields, accounting for details such as surface roughness, grain boundaries, and material inhomogeneities.

Machine Learning on Acoustic data sets
Description: Sound is one of the fundamental ways we observe our environment. In collaboration with acousticians at BYU and Blue Ridge Research and Consulting, we use machine learning techniques to predict ambient sound levels from environmental parameters (such as the distance to a road or local population densities). Our models will ultimately be useful for a variety of applications including military mission planning, public health, urban development, and ecology. We also use machine learning to predict crowd dynamics from acoustic data sets. Can analysis of acoustic data collected at sporting events be used to infer the shifting mood of a diverse crowd? If so, can acoustic monitoring be used to improve law enforcement responses to crowds before they become violent?

General Relativity
Description: General relativity describes gravitational phenomena geometrically as curvature in spacetime: Matter curves space, and the spacetime curvature affects matter. General relativity predicts that accelerating objects can emit gravitational radiation. While this radiation is typically extremely weak, some astrophysical systems, such as colliding black holes or neutron stars, may emit gravitational waves that we can detect on Earth. Large, kilometer scale laser interferometers, such as LIGO, are being constructed to study gravitational wave signals from these events. Unfortunately, we currently know very little about the radiation expected from the regions of spacetime with the strongest (nonlinear) gravitational fields. I study computational methods for solving the Einstein equations for these strongfield gravitational wave sources. Various projects are available to investigate black hole spacetimes, black hole formation, and properties of the Einstein equations. All projects require writing, testing, and running computer codes to investigate nonlinear gravitational phenomena.
Suitable For:
Undergraduate Students

REU StudentsNeeded Skills: Students should plan on spending a significant amount of time learning the fundamentals of general relativity, tensor analysis and computational methods as part of their research.

Relativistic fluid dynamics (RFD)
Description: Neutron star collapse, supernovae, gammaray sources, etc., are some of the exciting topics in relativistic astrophysics, and the perfect fluid is the fundamental model for all of these. I study relativistic perfect fluids near black holes using computational methods. In particular, Eric Hirschmann, Steven Millward and I at BYU are studying a magnetized fluid around a black hole with computational MagnetoHydrodynamics (MHD). Various computational projects are available in RFD and MHD, which require writing, testing and running computer programs to model relativistic fluids.
Suitable For:

Numerical methods
Description: Research with the Einstein equations and RFD requires sophisticated numerical methods and techniques (as well as cheats and tricks). Some techniques include adaptive mesh refinement (AMR), parallel computing, highresolution shockcapturing methods for fluid equations. Some systems, such as moving black holes, may naturally be solved in multiple reference frames simultaneously. I am investigating the use of overlapping computational grids for these problems. One particular interest is combining modern fluid methods with overlapping grids.
