Vortex interactions in the collision of Bose-Einstein condensates
Tao Yang, Andrew J. Henning, Keith A. Benedict
We investigate the effects of vortex interaction on the formation of interference patterns in a coherent pair of two-dimensional Bose condensed clouds of ultra-cold atoms traveling…
Bogoliubov excitation spectrum of an elongated condensate from quasi-one-dimensional to three-dimensional transition
Tao Yang, Andrew J. Henning, Keith A. Benedict
The quasiparticle excitation spectra of a Bose gas trapped in a highly anisotropic trap is studied with respect to varying total number of particles by numerically solving the effe…
Simulating quantum transport for a quasi-one-dimensional Bose gas in an optical lattice: the choice of fluctuation modes in the truncated Wigner approximation
B. Xiong, T. Yang, Keith A. Benedict
We study the effect of quantum fluctuations on the dynamics of a quasi-one-dimensional Bose gas in an optical lattice at zero-temperature using the truncated Wigner approximation w…
Distortion of Interference Fringes and the Resulting Vortex Production of Merging Bose-Einstein Condensates
Bo Xiong, Tao Yang, Keith A. Benedict
We investigate the effects of interatomic interactions and expansion on the distortion of interference fringes of a pair of initially well-separated, but coherent, condensate cloud…
