## PHYS441: Quantum Physics Autumn 2014

**Update Nov. 26:** HW
set 2 solutions, the Note
on Matrices in QM (previously distributed by EMAIL), and slides
for today's Thanksgiving
lecture (the first slide is an improved and corrected Fig. 34
from the Handout, the second slide contains a comprehensive picture
of the hydrogen spectra).

Update Nov. 12: and DRAFT of the are available.

Update Nov. 10: Exam
1 solutions available

**Update Oct. 30 **available.
Note, in problem 3, the horizontal fraction line should stop before
the potential V (i.e. V should not be divided by psi)

**Update Oct. 27, 2014 **Hwset1Part1
solutions available

**Update Oct. 19,2014:**

The syllabus, Lecture notes and corresponding Figures are in the
two packages you obtained from the RAMs Copy Center. In class last
week, I distributed an
update, with lecture on the expectation values and with
additional homework assignments for EXAM 1, also the Course
Schedule – these are linked to from here as a backup I case
you missed that class.

In the text, please fix the typesetting problem in the Taylor
expansion, and remove the extra multiplication by t in the expression
for the time-dependent part of the Schrodinger equation.

In addition to the quantitative problems, you may be asked to
briefly explain the main concepts
introduced in the lectures.

There are many animations of various quantum-mechanical features
available on the web. The one I used for the piece-wise-constant
potentials (and will use again on Monday) is at
