Phys622 Spring 1996 Announcements
Announcements are placed in reversed chronological order.
Date: Fri, 3 May 1996 21:22:07 -0400
Subject: Phys622: Last day of classes
The last class of Phys622 will be on Monday, May 13, and this is the
last day when I accept homework.
Date: Mon, 29 Apr 1996 15:17:04 -0400
Subject: Phys622: final exam
Final exam of Phys622 will be held on Tuesday, May 21, 1996, from 8 to
10 a.m. at room 1402. I allow to use any textbooks, notes, etc.
during the exam.
Date: Sat, 23 Mar 1996 19:16:54 -0500
Subject: Phys622: colloquium
The subject of the next week physics colloquium again involves modern
applications of quantum mechanics. You may be interested (but are not
required) to attend. The "entangled quantum states" are real fun.

4:00 p.m., Room 1410 PHYSICS COLLOQUIUM
Physics Building Non-Classical and Non-Local Effects in the
Interference of Light
Dr. Leonard Mandel, University of Rochester
Abstract:
>We are accustomed to think of optical interference as a classical wave
>phenomenon. However, a number of non-classical and non-local effects
>can show up when the field is in an entangled quantum state. Some of
>these will be described.

Subject: Phys622: Meeting on March 20
I wish to inform those who did not attend Phys622 today (Friday, March
15) that we decided to meet during the spring break on March 20 at 11
a.m. in the usual room in order to remedy difficulties encountered in
the homeworks we discussed so far (up to Homework 6, inclusive).
Attendance of this meeting is strictly optional. We will not discuss
solutions of any further homeworks. You are strongly advised to bring
your questions, otherwise there will be nothing to do.
Also, we might decide to spend more time in class during regular weeks
in order to discuss solutions more thoroughly. We are already
somewhat behind the schedule in discussing the solutions. If you
favor this idea, please, let me know by e-mail or in person.
There some corrections to Homework 7.
I did not pay attention that in Problem 8c the origin of the
delta-function is shifted to a. I presumed the delta(x) is considered
there. That is the reason for my Hint 8d.
Problem 11a requires quite long calculations in order to arrive to the
desired result. They can be done in a more economical way. Those
students who have not already solved Problem 11 may postpone solving
it till Homework 9, which will be devoted to motion in magnetic field.
In Homework 9, the Problem will be reformulated to provide a shorter
way for the derivation.

Subject: Phys622: Momentum representation
I was asked to indicate a reference where the momentum representation
of Schroedinger equation is explained. Among the books that I
recommended, it is given in Landau and Lifshitz, Section 130 ("The
scattering amplitude in the momentum representation"), page 535. The
numbers refer to the third edition.
If anybody knows other good sources, please, let us know.

Subject: Phys622: colloquium
The subject of the next week physics colloquium involves modern
applications of quantum mechanics. You may be interested (but are not
required) to attend. There was a popular (but not very
understandable) paper on the same subject in Physics Today, October
1995, page 24 by C.H.Bennett, who is also from IBM.
Tuesday, March 5, 1996 PHYSICS COLLOQUIUM
4:00 p.m., Room 1410 Quantum Computation
Physics Building Dr. David P. DiVincenzo, IBM Thomas J.
Watson Research Center
> Abstract
>
>Computers could be profoundly more powerful if the interference
>effects possible in quantum mechanics were exploited in their design.
>I present the logical primitives (the analog of AND and OR gates in
>classical boolean logic) needed for making a quantum computer. The
>physical implementation of a quantum computer requires extremely high
>quantum phase coherence, and I will review the prospects of such
>implementation in various many-particle quantum systems.
