Mean-field phase diagram of cold lattice bosons in disordered potentials
P. Buonsante, V. Penna, A. Vezzani +1
We show that a site-dependent mean-field approach captures the quantum phases of the disordered Bose-Hubbard model commonly adopted to describe ultracold bosons in random optical l…
Wannier states and Bose-Hubbard parameters for 2D optical lattices
P. B. Blakie, C. W. Clark
We consider the physical implementation of a 2D optical lattice with schemes involving 3 and 4 light fields. We illustrate the wide range of geometries available to the 3 beam latt…
Adiabatic loading of bosons into optical lattices
P. B. Blakie, J. V. Porto
The entropy-temperature curves are calculated for non-interacting bosons in a 3D optical lattice and a 2D lattice with transverse harmonic confinement for ranges of depths and fill…
Topological Atom Laser
P. Blair Blakie, Robert J. Ballagh, Charles W. Clark
We demonstrate how a topological atom laser can be realized by output coupling a trapped vortex state with a Raman scattering process. We find a linearized analytic solution from w…
