Confined Bosons on two-dimensional random lattices: a mean-field approach
P. Buonsante, F. Massel, V. Penna, und A. Vezzani. Abstract Book of the XXIII IUPAP International Conference on Statistical Physics, Genova, Italy, (9-13 July 2007)
Zusammenfassung
In the present paper we describe the properties induced by disorder on
an ultracold gas of Bosonic atoms loaded into a two-dimensional
optical lattice with global confinement ensured by a parabolic
potential. Our analysis is centered on the spatial distribution of
the various phases, focusing particularly on the superfluid properties
of the system as a function of external parameters and of disorder
amplitude. In particular, it is shown how disorder can suppress
superfluidity, while partially preserving the system coherence.
