**Course objectives**

This class provides
a solid introduction to the concepts and fundamentals of Quantum Mechanics. With
this course, you will learn the following concepts and will apply them to solve
the following situations:

1. The Schrodinger equation.

2. Probability, measurement outcomes, expectation values and standard deviation.

3. Heisenberg uncertainty principle

4. Time-Independent Schrodinger equation, and stationary states

5. Eigenstates and eigenvalues of an operator

6. Simple Harmonic Oscillator

7. Infinite square well and finite barrier potential

8. Free particle

9. Schrödinger equation in spherical coordinates

10. Hydrogen Atom and spherical harmonics

11. Angular Momentum and Spin

12 Two particles systems, atoms and solids

**Course materials**

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

We will follow this
class schedule** **

**CID/ Iclicker**

You can get your course ID
**here** .
Remember to indicate your CID on each piece of work you submit.

In order to answer in-class quizzes, you need to get your own
I-Clicker and register it
**here**.

**Homework**

**Here** you
will find your homework assignments, normally due twice a week: T and Th by **
7pm. **

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

Submit your homework in the reserved slots "Phys 451" 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**. **

**Group presentations**

There will be a few assignments throughout the semester where students will have the opportunity to present as groups.

The first group presentation will happen on Wednesday Sep 5th, and will focus on the famous scientists who contributed to the foundation of quantum mechanics. The assignement consist in gathering information about the chosen scientist (life and contribution to quantum mechanics) and prepare a 5 min presentation as a group in class on Sep 5th.

Other group presentation will happen later in the semesters and will mostly focus on preparing for exam and presenting solutions for practice tests.

Points will be assigned for group presentations, either as homework points or as quizzes points, as specified on the assignment.

**Exams**

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

Midterm 1: **Sep 24 - Sep 27**,
testing center

Midterm 2: **Oct 22 - Oct 25**,
testing center

Midterm 3: **Nov 26 - Nov 30**,
testing center

Final exam: **Wed Dec 12, 2012, 7am, **
in classroom C285 ESC

**Grading**

In-Class Quizzes on Reading (10% of grade)

Homework (40% )

Exams (30%)

Final (20%)

**Grading Policy**

Asssignments should be submitted on time.

Under exceptional circumstances, assignments may be submitted late. Please
contact the instructor before the deadline of the specific assignment, to
explain your situation and the reason why you can not submit it on time.

If an assignment is submitted late, with a valid excuse, and is submitted
within a reasonable time, it will be graded according to the regular
scale, based on full credit.

If an assignment is submitted late, with no valid excuse, it will receive a penalty, which will increase with the number of late days (typically loosing 2pts per late weekday)

One assignement (with the lowest score) will be dropped at the end of the semester when calculating final grade.

Quizzes will weight 10% of the final grade. Two of the quizzes (with lowest
score) will be dropped at the end of the semester when calculating final grade.
