Collective Oscillations in Trapped Bose-Einstein Condensed Gases in the Presence of Weak Disorder
G. M. Falco, A. Pelster, R. Graham
The influence of a weak random potential on the collective modes of a trapped interacting Bose-Einstein condensate at zero temperature is calculated in the limit when the correlati…
Thermodynamics of a Bose-Einstein Condensate with Weak Disorder
G. M. Falco, A. Pelster, R. Graham
We consider the thermodynamics of a homogeneous superfluid dilute Bose gas in the presence of weak quenched disorder. Following the zero-temperature approach of Huang and Meng, we…
Mean-field phase diagram of disordered bosons in a lattice at non-zero temperature
K. V. Krutitsky, A. Pelster, R. Graham
Bosons in a periodic lattice with on-site disorder at low but non-zero temperature are considered within a mean-field theory. The criteria used for the definition of the superfluid…
Spin-1 bosons with coupled ground states in optical lattices
K. V. Krutitsky, R. Graham
The superfluid--Mott-insulator phase transition of ultracold spin-1 bosons with ferromagnetic and antiferromagnetic interactions in an optical lattice is theoretically investigated…
