Theory of strong outcoupling from Bose-Einstein condensates
Robert Graham, Dan F. Walls
We study the dynamics of a magnetically trapped Bose-Einstein condensate in the presence of an external electromagnetic field coupling trapped, untrapped and antitrapped Zeeman sub…
Detection of vorticity in Bose-Einstein condensed gases by matter-wave interference
Eric L. Bolda, Dan F. Walls
A phase-slip in the fringes of an interference pattern is an unmistakable characteristic of vorticity. We show dramatic two-dimensional simulations of interference between expandin…
Measurement of relative phase diffusion between two Bose-Einstein condensates
Janne Ruostekoski, Dan F. Walls
We propose a method of measuring diffusion of the relative phase between two Bose-Einstein condensates occupying different nuclear or spin hyperfine states coupled by a two-photon…
Bose-Einstein condensate in a double-well potential as an open quantum system
Janne Ruostekoski, Dan F. Walls
We study the dynamics of a Bose-Einstein condensate in a double-well potential in the two-mode approximation. The dissipation of energy from the condensate is described by the coup…
Thermal Properties of Interacting Bose Fields and Imaginary-Time Stochastic Differential Equations
L. I. Plimak, M. Fleischhauer, D. F. Walls
Matsubara Green's functions for interacting bosons are expressed as classical statistical averages corresponding to a linear imaginary-time stochastic differential equation. This m…
Creation of vortices in a Bose-Einstein condensate by a Raman technique
Eric L. Bolda, Dan F. Walls
We propose a method for taking a Bose-Einstein condensate in the ground trap state simultaneously to a different atomic hyperfine state and to a vortex trap state. This can be acco…
