Strongly non-equilibrium Bose–Einstein condensation in a trapped gas

Role of trap-induced scales in non-equilibrium dynamics of strongly interacting trapped bosons.

We use a time-dependent hopping expansion technique to study the non-equilibrium dynamics of strongly interacting bosons in an optical lattice in the presence of a harmonic trap characterized by a force constant K. We show that after a sudden quench of the hopping amplitude J across the superfluid (SF)-Mott insulator (MI) transition, the SF order parameter [Formula: see text] and the local dens...

Non Equilibrium Dynamics in Strongly Correlated Systems

Thermostatistics of a Relativistic Gas: Equilibrium and Non-equilibrium Properties

The introduction of models to simulate dynamics of relativistic gaseous systems is among the latest efforts made in the recent decades to investigate the relativistic generalizations of statistical thermodynamics. Relativistic thermodynamics was born in the early 20th century to investigate the consequences of Einstien’s special relativity on thermodynamic systems. A simple and important questi...

Collapse and Bose - Einstein condensation in a trapped Bose gas with negative scattering length

We find that the key features of the evolution and collapse of a trapped Bose condensate with negative scattering length are predetermined by the particle flux from the non-equilibrium above-condensate cloud to the condensate and by 3-body recombination of Bose-condensed atoms. The collapse, starting once the number of Bose-condensed atoms N 0 reaches the critical value, ceases and turns to exp...
