Abstract: We theoretically investigate the collective excitations of a one-dimensional Bose–Einstein condensate with both interparticle interaction and quantum fluctuation effect in an anharmonic trap. We derive the coupled equations of motions for the center-of-mass coordinate of… read more here.

Abstract: Quantum fluctuation theorem (FT) commonly requires the system initially prepared in an equilibrium state. Whether there exists universal exact quantum FT for initial states beyond equilibrium needs further discussions. In the present paper, we initialize… read more here.
