Structure of the mean-field yrast spectrum of a two-component Bose gas in a ring: role of interaction asymmetry
Hui Tang, Guan-Hua Huang, Shizhong Zhang +2
The mean-field yrast spectrum of an SU(2)-symmetric two-component Bose gas confined to a ring geometry is known to exhibit an intricate nonanalytic structure that is absent in sing…
Mean-field yrast spectrum and persistent currents in a two-component Bose gas with interaction asymmetry
Z. Wu, E. Zaremba, J. Smyrnakis +3
We analyze the mean-field yrast spectrum of a two-component Bose gas in the ring geometry with arbitrary interaction asymmetry. Of particular interest is the possibility that the y…
Dynamics of harmonically confined systems: some rigorous results
Z. Wu, E. Zaremba
In this paper we consider the dynamics of harmonically-confined atomic gases. We present various general results which are independent of particle statistics, interatomic interacti…
Transition to the Giant Vortex State in an Harmonic Plus Quartic Trap
H. Fu, E. Zaremba
We consider a rapidly rotating Bose-condensed gas in an harmonic plus quartic trap. At sufficiently high rotation rates the condensate acquires an annular geometry with the superpo…
Novel low-energy collective excitation at metal surfaces
V. M. Silkin, A. Garcia-Lekue, J. M. Pitarke +3
A novel collective excitation is predicted to exist at metal surfaces where a two-dimensional surface-state band coexists with the underlying three-dimensional continuum. This is a…
Magnetoplasmon excitations in arrays of circular and noncircular quantum dots
B. P. van Zyl, E. Zaremba, D. A. W. Hutchinson
We have investigated the magnetoplasmon excitations in arrays of circular and noncircular quantum dots within the Thomas-Fermi-Dirac-von Weizsäcker approximation. Deviations from t…
