The two-dimensional Bose-Einstein condensate
Trapped bose gas low temperature condensation thermodynamics
2014/12/20
We study the Hartree–Fock–Bogoliubov mean-field theory as applied to a two-dimensional finite trapped Bose gas at low temperatures and find that, in the Hartree–Fock approximation, the system can be d...
Superfluid-Superfluid Phase Transitions in a Two-Component Bose-Einstein Condensate
Hamiltonian parameters bosons optical lattice superfluid superfluids vacuum
2014/12/20
Depending on the Hamiltonian parameters, two-component bosons in an optical lattice can form at least three different superfluid phases in which both components participate in the superflow: a (strong...
Nonlinear Bose-Einstein-condensate Dynamics Induced by a Harmonic Modulation of the s-wave Scattering Length
Nonlinear Bose-Einstein-condensate Dynamics Induced Harmonic Modulation the s-wave Scattering Length
2011/9/15
In a recent experiment, a Bose-Einstein condensate of 7Li has been excited by a harmonic modulation of the atomic s-wave scattering length via Feshbach resonance. By combining an analytical perturbati...

Dynamics a symmetric triple-well trap a Bose-Einstein condensate
2010/11/8
We present a complete analysis of the dynamics of a Bose-Einstein condensate trapped in a symmetric triple-well potential. Our classical analogue treatment, based on a time-dependent variational metho...

Decoherence quantum harmonic oscillator monitored Bose-Einstein condensate
2010/11/9
We investigate the dynamics of a quantum oscillator, whose evolution is monitored by a Bose-Einstein condensate (BEC) trapped in a symmetric double well potential. It is demonstrated that the oscillat...
Regular and chaotic Bose-Einstein condensate in an accelerated Wannier-Stark lattice
Regular and chaotic Bose-Einstein condensate Wannier-Stark lattice
2010/4/9
We investigate a Bose-Einstein condensate held in a quasi-one-dimensional Wannier-Stark lattice which is a combination of linear potential with an accelerated optical lattice. It is demonstrated that ...
Quantum dynamics of instability-induced pulsations of a Bose-Einstein condensate in an optical lattice
Quantum dynamics instability-induced pulsations Bose-Einstein condensate optical lattice
2010/4/13
We study the dynamics of a Bose-Einstein condensate in a one-dimensional optical lattice in the limit of weak atom-atom interactions, including an approximate model for quantum fluctuations. A pulsati...
