A finite-time quantum Otto engine with tunnel coupled one-dimensional Bose gases
V. V. Nautiyal, R. S. Watson, K. V. Kheruntsyan
We undertake a theoretical study of a finite-time quantum Otto engine cycle driven by inter-particle interactions in a weakly interacting one-dimensional Bose gas in the quasiconde…
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…
Correspondence between stochastic Wigner trajectories and individual experimental runs
R. J. Lewis-Swan, M. K. Olsen, K. V. Kheruntsyan
We examine the interpretation of individual phase-space trajectories of the Wigner function as corresponding to possible outcomes of single experimental trials. To this end, we inv…
Role of spatial inhomogeneity in dissociation of trapped molecular condensates
Magnus Ogren, K. V. Kheruntsyan
We theoretically analyze dissociation of a harmonically trapped Bose-Einstein condensate of molecular dimers and examine how the spatial inhomogeneity of the molecular condensate a…
Non-local pair correlations in the 1D Bose gas at finite temperature
P. Deuar, A. G. Sykes, D. M. Gangardt +3
The behavior of the spatial two-particle correlation function is surveyed in detail for a uniform 1D Bose gas with repulsive contact interactions at finite temperatures. Both long-…
A comparative study of dynamical simulation methods for the dissociation of molecular Bose-Einstein condensates
S. L. W. Midgley, S. Wuester, M. K. Olsen +2
We describe a pairing mean-field theory related to the Hartree-Fock-Bogoliubov approach, and apply it to the dynamics of dissociation of a molecular Bose-Einstein condensate (BEC)…
