Professor to discuss 'new frontier' in physics: ultra cold atoms

Jianbing_Qi

Dr. Jianbing Qi, Assistant Professor of Physics at Penn State Berks, will present "Making Ultra-cold Atoms and Molecules in the Lab" as part of the college's Division of Science Colloquium on Friday, February 20, from 1:00-2:30 p.m. in room 123 of the Luerssen Building. This lecture is free and open to the public, and light refreshments will be served.

Although the field of ultracold physics is relatively new, it's one of the hottest research areas right now and Qi's research is on the cutting edge.

"Ultra-cold atoms and molecules have opened up a new frontier in physics," explains Qi. "These studies at such low temperatures, ranging from millikelvin to nanokelvin (a billionth of a degree above absolute zero), have lead to many new insights about collisions, precision measurements, and the formation of Bose-Einstein condensation, degenerate Fermi gases, and ultra-cold molecules. A unique feature of ultra-cold atomic gases is the possibility of controlling their interaction strength experimentally. There are many applications of ultra-cold physics, such as superfluidity, quantum computing, and optical information processing."

Qi will discuss some basic physics and experimental techniques for laser cooling and trapping neutral atoms in dilute gas phases in a magneto-optic trap (MOT).

The Division of Science Colloquia features Penn State Berks faculty who conduct research on a wide variety of topics. Upcoming events will include a lecture by Dr. Dr. Dave Sanford, Associate Professor of Horticulture, titled " "The Greening of America, One Roof at a Time" " on Friday, March 20, 2009 from 1:00-2:30 p.m. in room 123 of the Luerssen Building.
