Pseudo-fermionization of 1-D bosons in optical lattices
Guido Pupillo, Ana Maria Rey, Carl J. Williams +1
We present a model that generalizes the Bose-Fermi mapping for strongly correlated 1D bosons in an optical lattice, to cases in which the average number of atoms per site is larger…
Ultracold atoms confined in an optical lattice plus parabolic potential: a closed-form approach
Ana Maria Rey, Guido Pupillo, Charles W. Clark +1
We discuss interacting and non-interacting one dimensional atomic systems trapped in an optical lattice plus a parabolic potential. We show that, in the tight-binding approximation…
Mean-field treatment of the damping of the oscillations of a 1D Bose gas in an optical lattice
Julio Gea-Banacloche, Ana Maria Rey, Guido Pupillo +2
We present a theoretical treatment of the surprisingly large damping observed recently in one-dimensional Bose-Einstein atomic condensates in optical lattices. We show that time-de…
Effects of finite temperature on the Mott insulator state
Guido Pupillo, Carl J. Williams, Nikolay V. Prokof'ev
We investigate the effects of finite temperature on ultracold Bose atoms confined in an optical lattice plus a parabolic potential in the Mott insulator state. In particular, we an…
