Collective many-body bounce in the breathing-mode oscillations of a Tonks-Girardeau gas
Y. Y. Atas, I. Bouchoule, D. M. Gangardt +1
We analyse the breathing-mode oscillations of a harmonically quenched Tonks-Giradeau (TG) gas using an exact finite-temperature dynamical theory. We predict a striking collective m…
Exact nonequilibrium dynamics of finite-temperature Tonks-Girardeau gases
Y. Y. Atas, D. M. Gangardt, I. Bouchoule +1
Describing finite-temperature nonequilibrium dynamics of interacting many-particle systems is a notoriously challenging problem in quantum many-body physics. Here we provide an exa…
Finite-temperature hydrodynamics for one-dimensional Bose gases: Breathing mode oscillations as a case study
I. Bouchoule, S. S. Szigeti, M. J. Davis +1
We develop a finite-temperature hydrodynamic approach for a harmonically trapped one-dimensional quasicondensate and apply it to describe the phenomenon of frequency doubling in th…
