Condensation of N interacting bosons: Hybrid approach to condensate fluctuations
Anatoly A. Svidzinsky, Marlan O. Scully
We present a new method of calculating the distribution function and fluctuations for a Bose-Einstein condensate (BEC) of N interacting atoms. The present formulation combines our…
Condensation of N bosons IV: A simplified Bogoliubov master equation analysis of fluctuations in an interacting Bose gas
Marlan O. Scully, Anatoly A. Svidzinsky
A nonequilibrium master equation analysis for N interacting bosons, with Bogoliubov quasiparticles as the reservoir is presented. The analysis is based on a simplified Hamiltonian.…
Fluctuations in Ideal and Interacting Bose-Einstein Condensates: From the laser phase transition analogy to squeezed states and Bogoliubov quasiparticles
Vitaly V. Kocharovsky, Vladimir V. Kocharovsky, Martin Holthaus +4
We review the phenomenon of equilibrium fluctuations in the number of condensed atoms in a trap containing N atoms total. We start with a history of the Bose-Einstein distribution,…
Insulator-Superfluid transition of spin-1 bosons in an optical lattice in magnetic field
A. A. Svidzinsky, S. T. Chui
We study the insulator-superfluid transition of spin-1 bosons in an optical lattice in a uniform magnetic field. Based on a mean-field approximation we obtained a zero-temperature…
Normal modes and stability of phase separated trapped Bose-Einstein condensates
Anatoly A. Svidzinsky, Siu-Tat Chui
We study the normal modes and the stability of two component condensates in a phase separated regime. In such a regime the system can undergo a quantum phase transition upon the ch…
Symmetric-Asymmetric transition in mixtures of Bose-Einstein condensates
Anatoly Svidzinsky, Siu-Tat Chui
We propose a new kind of quantum phase transition in phase separated mixtures of Bose-Einstein condensates. In this transition, the distribution of the two components changes from…
A new mechanism of neutron star radiation
Anatoly A. Svidzinsky
We find a new mechanism of neutron star radiation wherein radiation is produced by the stellar interior. The source of radiation is oscillating neutron vortices in the superfluid c…
Vortices in a trapped dilute Bose-Einstein condensate
Alexander Fetter, Anatoly Svidzinsky
We review the theory of vortices in trapped dilute Bose-Einstein condensates and compare theoretical predictions with existing experiments. Mean-field theory based on the time-depe…
Stability of a Vortex in a Rotating Trapped Bose-Einstein Condensate
Alexander L. Fetter, Anatoly A. Svidzinsky
We briefly discuss energy, normal modes and dynamics of a vortex in a trapped Bose-Einstein condensate. Theoretical results are compared with current experiments.
Dynamics of a Vortex in a Trapped Bose-Einstein Condensate
Anatoly Svidzinsky, Alexander Fetter
We consider a large condensate in a rotating anisotropic harmonic trap. Using the method of matched asymptotic expansions, we derive the velocity of an element of vortex line as a…
Vortex State Structure of a Bose Condensate in an Asymmetric Trap
Anatoly A. Svidzinsky, Alexander L. Fetter
Based on an analytic solution of the Gross-Pitaevskii equation in the large-condensate (Thomas-Fermi) limit we determine the structure of a stationary vortex in a Bose-Einstein con…
Stability of a Vortex in a Trapped Bose-Einstein Condensate
Anatoly A. Svidzinsky, Alexander L. Fetter
Based on the method of matched asymptotic expansion and on a time-dependent variational analysis, we study the dynamics of a vortex in the large-condensate (Thomas-Fermi) limit. Bo…
