Hanbury Brown-Twiss Interferometry for Fractional and Integer Mott Phases
Ana Maria Rey, Indubala I. Satija, Charles W. Clark
Hanbury-Brown-Twiss interferometry (HBTI) is used to study integer and fractionally filled Mott Insulator (MI) phases in period-2 optical superlattices. In contrast to the quasimom…
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…
Vortex line in a neutral finite-temperature superfluid Fermi gas
N. Nygaard, G. M. Bruun, B. I. Schneider +2
The structure of an isolated vortex in a dilute two-component neutral superfluid Fermi gas is studied within the context of self-consistent Bogoliubov-de Gennes theory. Various the…
Nonequilibrium Dynamics of Optical Lattice-Loaded BEC Atoms: Beyond HFB Approximation
Ana Maria Rey, B. L. Hu, Esteban Calzetta +2
In this work a two-particle irreducible (2PI) closed-time-path (CTP) effective action is used to describe the nonequilibrium dynamics of a Bose Einstein condensate (BEC) selectivel…
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…
Dynamics of a period-three pattern loaded Bose-Einstein condensate in an optical lattice
Ana M. Rey, P. B. Blakie, Charles W. Clark
We discuss the dynamics of a Bose-Einstein condensate initially loaded into every third site of an optical lattice using a description based upon the discrete nonlinear Schrodinger…
