Bogoliubov approach to superfluidity of atoms in an optical lattice
Ana Maria Rey, Keith Burnett, Robert Roth +3
We use the Bogoliubov theory of atoms in an optical lattice to study the approach to the Mott-insulator transition. We derive an explicit expression for the superfluid density base…
Consequence of superfluidity on the expansion of a rotating Bose-Einstein condensate
Mark Edwards, Charles W. Clark, P. Pedri +2
We study the time evolution of a rotating condensate, that expands after being suddenly released from the confining trap, by solving the hydrodynamic equations of irrotational supe…
Imaging the phase of an evolving Bose-Einstein condensate wavefunction
J. E. Simsarian, J. Denschlag, Mark Edwards +6
We demonstrate a spatially resolved autocorrelation measurement with a Bose-Einstein condensate (BEC) and measure the evolution of the spatial profile of its quantum mechanical pha…
