Title:

Exploring the Quantum Universe with Light

 

Host:

Stanley Pau

 

Abstract:

Did you know that the College of Optical Sciences holds the record for the coldest temperatures ever recorded in Arizona?  Or that optics and lasers are crucial for cooling matter to a few billionths of a degree above absolute zero?  Such ultracold gases of atoms, called Bose-Einstein condensates (BECs), are routinely made here at the University of Arizona.  They have become one of the hottest tools in physics research, from studies of the quantum mechanical world of the very small and cold, to principles involving the evolution and structure of the Universe.  In this colloquium, I will first describe how light is used to create, manipulate, and observe these cold objects. I will point out some of the remarkable relationships between BECs and laser light, and provide insight into an emerging field of physics:  coherent atom optics.  I will finally focus on how BECs and laser light can be used together in studies of fundamental physics, emphasizing recent experimental accomplishments of my research group at the College of Optical Sciences.
