Final project references
Hey Class,
Only a few of you have sent me a reference list for your final projects. Everyone should do this soon! I've posted what I've got on the final project section of the website.

Class review — 4/19
Hey Class,
Recall that Onur, Andrea, Man-Hong, and Xu Wang are giving talks on Thursday. I will provide snacks :) Also remember to put in a vote (via email) to me if you want an extra, bonus class on atomic collisions (and quantum mechanical scattering theory).
Today we talked about:

Lecture notes up, etc.
Hey Class,
The lecture notes on laser cooling are available, and I've posted some reading material on resonance fluorescence if you're interested (see the class notes for 4/19).
Cheers,
Brian

Class Revew — 4/14
Class,
Make sure that you read this entire entry -- there is information on the talks you will be giving!
For your talks, plan on 13 minutes plus 5 minutes for questions. Do not plan on using the board -- instead, use Powerpoint or transparencies. I can provide you with transparencies of various kinds. I can also supply a laptop for use during your talk. Let me know in advance if you will be using Powerpoint.
I need to clean up the lecture notes on Sysiphus cooling before I post them. There will be no pre-flight for Monday, but I will post reading material on resonance fluorescence for those of you who are interested.
Yesterday in class we talked about:

Final project talks coming soon!
Hey Class,
Only one of you has signed up to give her final project talk. These talks will start next week (Thursday) and will take up the last 4 class periods!
Each of you needs to sign up for a date (4/21,4/26,4/28, or 5/3) to give your talk. Send me an email -- first come first served. If you do not send me an email (by 5 pm today) then I will randomly assign you to a date.
I will give more details about the talk in class today. We will finish up laser cooling, then do resonance fluorescence, and then you guys are basically teaching the rest of the class.
Also remember that the final project is due by 5/13. I will not and cannot be flexible on that date.

Note from Man-Hong on "Energy-time Uncertainty relation"
Hey Everyone,
Man-Hong sends this comment our way:
I accidentially found a comment by Seth Lloyd, in his nature article "Ultimate physical limits to computation". It is said that
"In particular, the correct interpretation of the time-energy Heisenberg uncertainty principle [DE Dt >= hbar] is not that it takes time Dt to measure energy to an accuracy DE (a fallacy that was put to rest by Aharonov and Bohm) but rather that that a quantum state with spread in energy DE takes time at least [Dt = pi hbar / 2 DE] to evolve to an orthogonal (and hence distinguishable) state."

Class review — 4/12
Hey Class,
Don't forget that there is a pre-flight for Thursday. Don't do it at the last minute!

Error in lecture notes
Hey Class,
Shizhong found an error in my lecture notes on a quantum atom interacting with the quantum EM field. My definition of the saturation intensity was off by a factor of the wavelength. I'll update the online lecture notes right away!
