Title: An Example of a Quantum Anomaly in Physics of Cold Atomic Gases
Speaker: Dr. Maxim Olchanyi, Univ of Massachusetts
Institute: University of Massachusetts at Boston
Location: ABB 102
Description:
In this presentation, we show that for the two-dimensional harmonically trapped Bose gas, the Pitaevskii-Rosch dynamical symmetry becomes weakly broken under quantization. The very same symmetry remains intact for the unitary three-dimensional gases. We interpret this effect as a quantum-mechanical symmetry breaking—otherwise known as quantum anomaly—, give a detailed quantitative analysis of its empirical manifestations, and suggest a detailed experimental scheme for its detection.
