Collapse and revival oscillations as a probe for the tunneling amplitude in an ultra-cold Bose gas
arXiv:1010.1776 · doi:10.1103/PhysRevA.82.043601
Abstract
We present a theoretical study of the quantum corrections to the revival time due to finite tunneling in the collapse and revival of matter wave interference after a quantum quench. We study hard-core bosons in a superlattice potential and the Bose-Hubbard model by means of exact numerical approaches and mean-field theory. We consider systems without and with a trapping potential present. We show that the quantum corrections to the revival time can be used to accurately determine the value of the hopping parameter in experiments with ultracold bosons in optical lattices.
