# PHYSICS 402 COURSE DESCRIPTION Spring 2017

## DESCRIPTION:

Physics 402: Quantum Physics II: Quantum states as vectors; spin and
spectroscopy, multiparticle systems, the periodic table, perturbation theory,
band structure, etc. The second semester of the two-term sequence on
introduction to quantum physics for physics majors. *This is a 4-credit
course.*
## PREREQUISITE:

PHYS 401, and PHYS 274, or MATH 240. A good working knowledge of
linear algebra and differential equations is important.
## LECTURES:

- Monday, Wednesday, Friday 9:00-9:50 AM; Toll 1201
- Wednesday Discussion 10:00-10:50am; Toll 1201

## INSTRUCTOR:

## TEXT AND REFERENCES:

- K. Krane, "Modern Physics 2nd Ed.", ISBN: 0-471-82872-6

## LECTURES:

You will be responsible for material presented in lecture that is not in the
book. If you miss a lecture you are responsible for finding out from a
classmate what we did in class.
## OFFICE HOURS:

You are strongly encouraged to attend office hours to ask questions, discuss
the homework problems, and talk about physics in general. The office
hours will be held 3:00-4:30 PM on Thursdays, just before the homework is
due.
## HOMEWORK:

The homework assignments will be given on the class website. The
assignment will be due at the beginning of class on Fridays. *Please staple
papers and show your name, assignment number and date due.* Two
homework problems will be graded quantitatively (0-10) and the rest will be
graded qualitatively (0-2). The choice of the two problems to grade
quantitatively will be made after the homework is collected.
Doing the homework is a very important part of this course!
Homework will be returned by the following week. Late homework will
not be accepted. As compensation, the lowest homework grade from the
semester will be dropped.
## EXAMS:

There will be two “mid-term” exams and a final exam. All exams will be
counted towards your final grade. Make-up exams (for any of the exams)
must be requested well in advance of the exam; the reason for the absence
must be documented and in accord with University policy (see p. 33 of
this document).
If an exam is unexpectedly canceled (due to inclement weather, etc.) it is automatically rescheduled for the next class period.
In grading, we are looking more at the reasoning that you use,
rather than the final number you arrive at. So remember to carefully set up
the problem on paper, even if you cannot see the way through to the
solution.
The final exam is *Wednesday, May 17, from 8 to 10 AM.*
## COMPUTERS:

Developing a working knowledge of computers in the context of physics
problem solving is an important skill. You are encouraged to solve
problems using programs such as Mathematica. Note that a student version
of Mathematica is available for download from TERPware:
http://terpware.umd.edu/Windows/Title/1837.
## IMPORTANT DATES:

- First meeting: January 25
- Spring Break: March 19-26
*Last day to drop with a "W": April 5*
- Last day of Classes: May 11
*Final exam: May 17*

## ACADEMIC DISHONESTY (CHEATING):

Academic dishonesty is a serious offense that can result in suspension or expulsion from the university. In addition to any other action taken, the normal sanction is a grade of "XF", denoting "failure due to academic dishonesty," and will normally be recorded on the transcript of the offending student. Students are required to perform all experiments, analysis, and write-ups independently. The experiments may be discussed with other students, but each student must work independently.
## TIPS FOR DOING WELL:

- Read the assignment in the book before and after the material is covered
in lecture.
- Freely ask questions in lecture, after lecture, and during office hours.
Also discuss problems with your friends and classmates.
- Work all of the homework questions and problems. You are allowed
and encouraged to discuss homework with anyone you wish. However, in
order to really learn, don’t just copy solutions from somewhere or someone
else; rather, work through them in detail yourself. Afterwards, make use of
the solution sets, your TA’s office hours, and me to make certain you
understand all of the solutions. The exams will sometimes involve
homework problems.
- Seek help immediately if you do not understand the material or can’t
solve the problems. Help is available from your TA, and from me. Don’t
wait until just before the exams! If you are experiencing difficulties in
keeping up with the academic demands of this course, contact the Learning
Assistance Service. Their educational counselors can help with time management, reading, notetaking and exam preparation skills.
- Remember that you are responsible for material discussed in class, even
if it does not appear in the textbook.

## PHYSICS GRE:

There is an emphasis on both historical aspects of quantum physics, as well
as many general concepts from one-dimensional quantum mechanics on the
Physics GRE exam. The textbook by Krane will be of great help in
preparing for the historical aspects, while Griffiths is ideal for the analytical
part of the exam. The more practice you have solving problems in quantum
mechanics, the better you will do on the Physics GRE.
## CourseEvalUM SPRING 2017:

Participation in the evaluation of courses through CourseEvalUM is a student responsibility held as a member of our academic community. Feedback is confidential and important to the improvement of teaching and learning at the University as well as to the tenure and promotion process. CourseEvalUM will be open for students to complete evaluations for spring semester courses starting about two weeks before the last day of classes. Go directly to the website CourseEvalUM to complete the evaluations. Completing all evaluations each semester gives online access at Testudo to the reports of the thousands of courses for which 70% or more students submitted their evaluations.
