Prof. Mark Havey, our old friend from Old Dominion University, and Dr. Dmirty Kupriyanov, our new friend from St. Petersburg Politechnic University, visited us today for a productive afternoon of physics discussions.
Graduations are always bitter-sweet, and today we are saying goodbye to two members of the group who were with us almost from the very beginning of the lab. William Ames is heading to the graduate program in Physics in the University of Colorado, Boulder.
Joseph Goldfrank is following his life-long dream - to be an officer at a nuclear submarine. First step after college - U.S. Navy Officer Candidate School, and then Naval Nuclear Power School.
And luckily, we still don’t need to part with this guy for a few years - Matt Simons got his Master of Science degree today!
Dr. Yanhong Xiao, former colleague of Irina at CfA and now a professor at Fudan University (China) visited our group and presented an AMO seminar.

of the Optical Society of America.
More party pictures here!
Today we were saying good-bye to two wonderful summer
REU students: Martha Roseberry (College of Wooster) and Tom Noel (U. of
Wisconsin). Both of them accomplish a lot for the short 10 week! Martha
built an optical network that connects our laboratory with the laboratory
of Dr. Seth Aubin for future sharing of a Ti:Sapphire laser.
Tom conducted a very detailed
experimental study of quantum noise properties near atomic resonance. He
is also a current world-wide record holder on polarization self-rotation
squeezing: -1.2dB below the shot noise limit. (Ok, may be the number
is not too impressive, but hey! - that’s the best for our method!)
We’ve been so busy here this summer, we didn’t even
have time to post anything! Here is our hard-working summer crew - at
work and at Sunday cookout.
From left to right: Tom Noel (summer REU student from
U. of Wisconsin), Will Ames, Matt Simons, Nathan Belcher, Nate Phillips,
Martha Roseberry (summer REU student from C. of Wooster), Eugeniy

Matt Eisaman, Eugeniy, Will Ames and Tom Noel (our summer REU student).
This year our group presented the results of the squeezing experiment and stored light optimization experiment at DAMOP conference that took place at State College, PA. On the photo below Nate Phillips explains the magic of slow light to unidentified physicist.
Recently we have submitted two papers describing our work on stored light optimization: arXiv:0805.3348 and arXiv:0805.1927! To celebrate the occasion we have recreated the William&Mary logo: we send a “W” into a vapor cell, and it was magically transformed into “M” at the output after being optimally stored in atomic spins.
In addition it turned out that the photo of AMO group in
William&Mary has been featured at June 2008 Optics&Photonics
News magazine!
Click on picture to enlarge.
Congratulations to Nathan Belcher, who successfully complete his work for BS in Physics! Since Nathan will officially graduate only in December, he will stay with us for the summer to more exciting work on atomic clocks!
Congratulations to Nate Phillips for winning the first place in Physical sciences in the student poster competition during Hampton Roads 2008 Research Expo. (Left) Our team together with Dr. Seth Aubin’s group members at the poster session. (Right) The happy winner a minute after the prizes were announced.

Dr. Wolfgang Ketterle (MIT) visited our lab during his visit to W&M.
Very productive week for our group! First news is that the first paper based solely on the experimental results from our lab in William and Mary. E. E. Mikhailov and I. Novikova, “Low-frequency vacuum squeezing via polarization self-rotation in Rb vapor,” submitted to Opt. Lett. (2008).
Second news - we have a home-made atomic clock working in the lab! We can lock frequency of rf oscillator to CPT resonance and improve its stability more than two orders of magnitude. The overall stability is not great, and we will be working on improving it with clever CPT resonance schemes.
Will Ames is conducting the experiment which will use optical vortices phase masks for optical filtering. The intensity distributions of a laser beam passed through the phase mask with and without interference are shown in Figs. (a) and (b) for a single m=1 vortex, and two vortices close to each other in Figs. (c) and (d). The phase mask is generously lended to us by Dr. Grover Swartzlander (University of Arizona).
