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…
Theoretical investigation of thermostability of incompressible channels in quantum Hall states
Tao Yang, Keith A. Benedict
In this work we use self-consistent method considering a two dimensional electron gas system in the integer quantum Hall regime, to calculate the temperature induced decay of incom…
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…
Anisotropic magnetic field dependence of many-body enhanced electron tunnelling through a quantum dot
E. E. Vdovin, Yu. N. Khanin, O. Makarovsky +6
We investigate the effect of an applied magnetic field on resonant tunneling of electrons through the bound states of self-assembled InAs quantum dots (QDs) embedded within an (AlG…
Dynamical Instabilities in a two-component Bose condensate in a 1d optical lattice
Samantha Hooley, Keith A Benedict
In this paper we carry out a stability analysis of the Bloch states of a two-component Bose-Einstein condensate confined to a 1d optical lattice. We consider two concrete systems:…
Surface Instabilities on Liquid Oxygen in an Inhomogeneous Magnetic Field
A. T. Catherall, Keith A Benedict, P. J. King +1
Liquid oxygen exhibits surface instabilities when subjected to a sufficiently strong magnetic field. A vertically oriented magnetic field gradient both increases the magnetic field…
