  • Learning objectives:

This course follows the Phys 451 course, typically offered in the Fall - Phys 451 is a prerequisite for Phys 452.

In  Phys 452, we will learn how to use the formalism and fundamentals of Quantum Mechanics, covered in Phys 451, to solve specific quantum problems and apply it to physical situations. We will also learn additional tools, like the pertubation theory, variational principle and WKB approximation. Applications will include finding the atomic levels of Hydrogen, Helium atoms, and basic molecules, or describing the effect of electromagnetic interactions between electrons in the matter and external fields, or describing absorption, radiation and light scattering phenomena.

 

 At the end of the Phys 452 course, you  should be able to:     

- Apply techniques such as perturbation theory, variational principle, and WKB approximation to find out the allowed energies of quantum systems.

- Understand the physical origin of fine-structure, hyperfine, and Zeeman level splitting in atoms.

- Characterize emission and absorption of radiation by atoms, and derive the associated selection rules.

- Describe and solve quantum scattering and tunneling problems.

 

This course should be a great preparation for graduate school and graduate research, especially, but not exclusively,  in the fields of condensed matter, atomic and molecular optics, theory of quantum physics, and chemistry. 

Your learning outcomes will be assessed throughout the semester with in-class quizzes, homework twice a week, two midterms exams, and a comprehensive final test.

 

  • Textbook- Reading schedule

Textbook: David J. Griffiths, Introduction to Quantum Mechanics, 2nd ed.

We will follow this Class Schedule Winter 2012

 

  • Course ID / I clicker

You can get your course ID here. Remember to indicate your CID on each of your homework and each of your tests.

  • Homework

Homework assignments are due twice a week:

There will be helping sessions on T and Th nights, room N337 ESC (undergraduate lab):

Submit your homework in the reserved slots "Phys 451/452" across N373 ESC

For best learning results and to get best scores, I strongly encourage you to explain your reasoning, method and findings in sentences as much as possible, together with your calculation.  

 

  • Exams

There will be 3 mid-term exams and one final exam. The exams are time limited for 3 hours, closed books.

Exam IFri Feb 3- Mon Feb 6, 2012 - Testing center

Exam IIMon Mar 5 - W Mar 7 Testing center

Final exam :  Sat April 14, 2:30pm C247 ESC
