Dynamical Kosterlitz-Thouless Theory for Two-Dimensional Ultracold Atomic Gases
Zhigang Wu, Shizhong Zhang, Hui Zhai
In this letter we develop a theory for the first and second sound in a two-dimensional atomic superfluid across the superfluid transition based on the dynamic Koterlitz-Thouless th…

Manipulation of heteronuclear spin dynamics with microwave and vector light shift
Lintao Li, Bing Zhu, Bo Lu +2
We report the observation and manipulation of heteronuclear spin dynamics in a spin-1 mixture of ultracold Rb and Na atoms. The dynamics is driven by the interspecies…

The Role of the Effective Range in Resonantly Interacting Fermi Gases: How Breaking Scale Symmetry Affects the Bulk Viscosity
Jeff Maki, Shizhong Zhang
We investigate the role of the effective range on the bulk viscosity of - and -wave Fermi gases. At resonance, the presence of the effective range breaks the scale invariance…
