CAP Lecture


Laser cooled atoms and atom chips: the new frontier of quantum electronics

Jim Martin
University of Waterloo

Time
 
Tue. January 10, 2012     4:30 PM     Stirling D

Abstract
 

"Atom chips" allow the manipulation of ultra-cold laser cooled atoms using microfabricated wire structures. Current-carrying wires on the chip surface generate inhomogeneous magnetic fields, allowing cold atoms to be held by the same forces as those in the famous Stern-Gerlach experiment. By varying the currents in the wires, the atoms can be squeezed into small volumes, and put at specific distances away from surfaces. I will discuss some of the applications of these atom chips to fundamental physics, including the production and study of Bose-Einstein condensates and fluctuating fields near surfaces.

Refreshments will be available before the talk.
