Hi, Could you please fix the link for midterm #2 solutions?
I would like to see them before the comps tomorrow.

Dear All,

With regards to $k^2 + \kappa^2$, which by some of you was
read as $2k^2$, in spite of the fact that this examples was
discussed in the lecture. We have that

f(k,k') = \frac{ik -\kappa}{k^2 +\kappa^2}

meaning that the r.h.s. does not depend on $k'$. Because
the proctorer added to the confusion I graded very mildly
if you did not interpret this problem correctly.

Have a nice summer,

Jac


PS. Grades can only be submitted to the solar system
on Monday. I hope to that that from Korea, but it
could be that it does not work. All grades (except 3)
are next to my door behind the pillar.

In mid3 Problem 1 b), why we must write k^2+k^2 instead of 2k^2? I am confused. f(theta=0)=f(k,k), isn't it correct?

In homework set# 8 solution, two last pages in problem 3: solution to unknown problem !

I believe in homework # 6, Problem 3 solution, one page missing.

- Tuesday, April 29, 2003 at 22:05:50 (EDT)

Dear All,

Indeed, the Dirac equation is not included in the test.

Tomorrow you will get back homework sets 6 and 7.

Jac

- Monday, April 28, 2003 at 21:51:00 (EDT)

can you return to us old homeworks on tuesday before the test?

- Friday, April 25, 2003 at 13:12:21 (EDT)

Thus Dirac Equation will not be included in the midterm, right?
Also, we never have problem about identical particles.
What kind of problem will it be for that part?

Dear All,

The homework set # 8 is now linked. I will post the solution
of # 7 tonight.

The material for the last midterm (May 1) will be

scattering
identical particles
homework problems on scattering

I will post the solutions of set 8 on Tuesday after
the lecture, which means that the formal deadline will
be the real deadline for submission of the homework.
Anyway, doing the homework is good practice to study for
the midterm.

Jac

- Thursday, April 24, 2003 at 14:57:58 (EDT)

the homework is not online yet, when will it be?

- Thursday, April 24, 2003 at 13:28:05 (EDT)

Would you like to post the homework solution as soon as possible?

- Wednesday, April 23, 2003 at 11:42:42 (EDT)

Where is the new homework? The last midterm will include HW set 6,7 and the coming 8? What materials will it cover? Thanks!

- Wednesday, April 23, 2003 at 11:39:52 (EDT)

great!
I think that may first is a good option!!

- Tuesday, April 22, 2003 at 14:40:08 (EDT)

where is the new homework?
why don't you drop a scattering problem and add an identical particle problem? so we have different things for the test!
:-)

- Tuesday, April 22, 2003 at 14:36:45 (EDT)

Dear All,

We will discuss in class when we will have the last midterm.
One proposal would be May first.

Jac

- Thursday, April 17, 2003 at 17:48:57 (EDT)

on which day will we have the last midterm?

If we take care of the boundary consition at r=0,
I think the ground state of the 3d SHO is
\psi \sim H_1(r)*\exp(-m\omega r^2/(2\hbar))
where H_1 is the hermite polynoimal

- Monday, April 07, 2003 at 16:23:32 (EDT)

The ground state of the 3d SHO is

\psi \sim \exp(-m\omega r^2/(2\hbar))

This is a Gaussian.

can't load your files in today's lecture. pls fix it. thanks

Can't download lecture notes, from page 84 on. Access denied, error 403.Can you please correct? Thank you.

- Tuesday, April 01, 2003 at 06:52:01 (EST)

the latest HW, Q4, is there something wrong? the ground state wavefunction of a 3D SHO should not be a Gaussian. But the question seems to expect us to use a Gaussian.

- Monday, March 31, 2003 at 14:10:08 (EST)

This problem has been corrected.

Hello! In the lecture notes, Lecture 11 occurs 2 times (under 11 and 12). Under "lecture 13" lecture 12 is linked, and the next one is lecture 14, so lecture 13 is not linked (although the file exists). I'm only talking about the html-files, not the single pictures.

So epslon(t) should be treated as the perturbation, it should much smaller than H0? In the problem it says epslon is much biger than delta, how can we consider it as a perturbation? I am not clear with the problem.

- Sunday, March 09, 2003 at 00:16:01 (EST)

Hi,

Although I did not look in detail at the first problem of
set 5, it is a two state problem and, although we now have
a different time dependence, it should be treated in the
same way as we did in the lecture for a harmonic time
dependence.

Best, Jac

- Friday, March 07, 2003 at 14:28:22 (EST)

In the first problem of HW5, it says epslon is much larger than delta, so how can we use perturbation theory? Would you like to give me some hint? Thanks a lot!

can we talk of density matrix formalism?

Hi, will you go over something for midterm1? Thanks.

- Monday, February 24, 2003 at 21:54:31 (EST)

Hi,

thanks for your comments about the schedule. I am very much
looking forward to more comments, and based on the input,
I will revise the schedule.

Jac

- Thursday, February 20, 2003 at 21:38:01 (EST)

I have seen your schedule. May be it contains too much stuff on scattering. How about the berry phase, casimir effect etc, they are more interesting.

- Thursday, February 20, 2003 at 15:52:23 (EST)

Thanks for the one page notes. However, I am not sure if it is possible for you to print out a problem sheet with OK format and make copies for us. I will be much appreciated if you may hand out the copies in class.

- Friday, February 14, 2003 at 14:38:51 (EST)

Yes. The pixel size was to do with homework set#3.

Hi --problem 5.21 of Sakarai

Some of you were in my office this afternoon with questions on
5.21. Although we got the correct answer on the blackboard:

\bar H = 3/\alpha^2 + \alpha/4 with minimum at \alpha^3 = 24, I did not calculate the result correctly on my
calculator. I get for \bar H = 1.0817, which is not too far
from the exact result.

- Thursday, February 13, 2003 at 21:01:17 (EST)

Hi,

With regards to the pixel size, does this refer to one of
my scanned pages? Otherwise, I do not know what to do with
this remark.

Best, Jac

- Thursday, February 13, 2003 at 18:06:32 (EST)

A note on scanning:
a 5 by 7 inch image scanned at 200 dpi generates a 1000 by 1400 pixel image. The scaling is linear.

- Thursday, February 13, 2003 at 09:18:58 (EST)

Hi,

I have been thinking about putting everything in one file.
If someone has a good suggestion I would like to hear it!
The problem is a keep the file size manageable so that
it still can pass in a reasonble time through a 56k
modem. I could convert .gif files to .ps files, but
that results in 2 M files per page. Conversion of .jpeg
into .ps gives files that are not readable. I will keep
playing with it.

Is it possible you combine all images for one lecture into a single file? Now, it's quite troublesome to print them one by one. Thanks

Hi,

When I print the notes they are with edges. Indeed, I try to
keep both a left and a right margin, but sometimes I go
to close to the right edge. I will try to stay away from
that. One possibility is to use another browser.

With regards to the readability, I am aware of that. I am
experimenting with different formats. Next time, if
everything works, everything will be posted in .gif
format instead of .jpeg format.

I am happy to slow down my pace. One effective way to
slow me down is to ask questions. Remember, there is
not such a thing as a "stupid question".

Best, Jac

- Monday, February 10, 2003 at 17:38:51 (EST)

I feel your lectures are too fast, I can not follow you well. Would you slow down a little bit? Thank you very much.

- Monday, February 10, 2003 at 12:13:13 (EST)

Homework set2 is not readable. Also the notes online are without edges. Would you mind to scan them carefully?

- Monday, February 10, 2003 at 12:10:15 (EST)

About homework: Problem 5c

In the lecture we showed that: \theta|j,m>=|j,-m>, up to a phase. I don't how to reconcile this and problem 5c.

Hi, I prepare the lecture the night before the class and
post the lecture notes when I am done. This can be quite
late such as for example today when I finished at 1.15 a.m.

Thanks for telling that you could not download them. I had
forgotten to chmod one page.

Best, Jac

- Tuesday, January 28, 2003 at 01:25:41 (EST)

Are the lecture notes going be posted online on a regular basis? Doing that would help us better prepare for the classes.
