Intrinsic Heating and Cooling in Adiabatic Processes for Bosons in Optical Lattices
Tin-Lun Ho, Qi Zhou
We show that by raising the lattice "adiabatically" as in all current optical lattice experiments on bosons, even though the temperature may decrease initially, it will eventually…
Vortices and phase transitions of interacting bosons in a rotating lattice ring
Qi Zhou
We investigate the ground state properties of the repulsive interacting bosons in an one dimensional rotating lattice ring, and reveal that the superfluid density of the system and…
Criterion for bosonic superfluidity in an optical lattice
Roberto B. Diener, Qi Zhou, Hui Zhai +1
We show that the current method of determining superfluidity in optical lattices based on a visibly sharp bosonic momentum distribution can be misleading, for even a n…
Vortex Dipole in a Trapped Atomic Bose-Einstein Condensate
Qi Zhou, Hui Zhai
We calculate the angular momentum and energy of a vortex dipole in a trapped atomic Bose-Einstein condensate. Fully analytic expressions are obtained. We apply the results to under…
Double-Layer Bose-Einstein Condensates with Large Number of Vortices
Hui Zhai, Qi Zhou, Rong Lv +1
In this paper we systematically study the double layer vortex lattice model, which is proposed to illustrate the interplay between the physics of a fast rotating Bose-Einstein cond…
Understanding of the Vortex Lattice Behavior Induced by Selective Removal of Atoms from a Bose-Einstein Condensate
Hui Zhai, Qi Zhou
It is known that the quantized vortices in a superfluid can be described by a dual electromagnetic model through the duality transformation. Recently a new technique, which can sel…
