Hierarchical dimensional crossover of an optically-trapped quantum gas with disorder
文献摘要：
Dimensionality serves as an indispensable ingredient in any attempt to formulate low-dimensional physics,and studying the dimensional crossover at a fundamental level is challenging.The purpose of this work is to study the hierarchical dimensional crossovers,namely the crossover from three dimensions(3D)to quasi-2D and then to ID.Our system consists of a 3D Bose-Einstein condensate trapped in an anisotropic 2D optical lattice characterized by the lattice depths V1 along the x direction and V2 along the y direction,respectively,where the hierarchical dimensional crossover is controlled via Vi and V2-.We analytically derive the ground-state energy,quantum depletion and the superfluid density of the system.Our results demonstrate the 3D-quasi-2D-lD dimensional crossovers in the behavior of quantum fluctuations.Conditions for possible experimental realization of our scenario are also discussed.
