Quench Dynamics and Emergence of Phase Separation in Two-Component Atomic Bose Gases at Zero Temperature and above the BEC Critical Temperature
Chih-Chun Chien, Fred Cooper
We study the dynamics of two-component atomic Bose gases initially in a mixture encountering a sudden quench of the inter-species interactions. The dynamics above the critical temp…

Large-N approximation for single- and two-component dilute Bose gases
Chih-Chun Chien, Fred Cooper, Eddy Timmermans
We discuss the mean-field theories obtained from the leading order in a large- approximation for one- and two- component dilute Bose gases. For a one-component Bose gas this app…

Mean-field description of pairing effects, BKT physics, and superfluidity in 2D Bose gases
Chih-Chun Chien, Jianhuang She, Fred Cooper
We derive a mean-field description for two-dimensional (2D) interacting Bose gases at arbitrary temperatures. We find that genuine Bose-Einstein condensation with long-range cohere…
