Exact coherent states of a harmonically confined Tonks-Girardeau gas
A. Minguzzi, D. M. Gangardt
Using a scaling transformation we exactly determine the dynamics of an harmonically confined Tonks-Girardeau gas under arbitrary time variations of the trap frequency. We show how…
Collective modes and ballistic expansion of a Fermi gas in the BCS-BEC crossover
Hui Hu, A. Minguzzi, Xia-Ji Liu +1
We evaluate the frequencies of collective modes and the anisotropic expansion rate of a harmonically trapped Fermi superfluid at varying coupling strengths across a Feshbach resona…
Collisional oscillations of trapped boson-fermion mixtures approaching collapse
P. Capuzzi, A. Minguzzi, M. P. Tosi
We study the collective modes of a confined gaseous cloud of bosons and fermions with mutual attractive interactions at zero temperature. The cloud consists of a Bose-Einstein cond…
Collective oscillations of a confined Bose gas at finite temperature in the random-phase approximation
Xia-Ji Liu, Hui Hu, A. Minguzzi +1
We present a theory for the linear dynamics of a weakly interacting Bose gas confined inside a harmonic trap at finite temperature. The theory treats the motions of the condensate…
Collective excitations in trapped boson-fermion mixtures: from demixing to collapse
P. Capuzzi, A. Minguzzi, M. P. Tosi
We calculate the spectrum of low-lying collective excitations in a gaseous cloud formed by a Bose-Einstein condensate and a spin-polarized Fermi gas over a range of the boson-fermi…
