Dynamical quantum noise in Bose-Einstein condensates
M. J. Steel, M. K. Olsen, L. I. Plimak +5
We introduce the study of dynamical quantum noise in Bose-Einstein condensates through numerical simulation of stochastic partial differential equations obtained using phase space…
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…
Non-Markovian quantum trajectories for spectral detection
M. W. Jack, M. J. Collett, D. F. Walls
We present a formulation of non-Markovian quantum trajectories for open systems from a measurement theory perspective. In our treatment there are three distinct ways in which non-M…
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…
Generic model of an atom laser
B. Kneer, T. Wong, K. Vogel +2
We present a generic model of an atom laser by including a pump and loss term in the Gross-Pitaevskii equation. We show that there exists a threshold for the pump above which the m…
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…
