The 17/5 spectrum of the Kelvin-wave cascade [PDF]
, 2010 Direct numeric simulation of the Biot-Savart equation readily resolves the 17/5 spectrum of the Kelvin-wave cascade from the 11/3 spectrum of the non-local (in the wavenumber space) cascade scenario by L'vov and Nazarenko.

Anomalous particle-number fluctuations in a three-dimensional interacting Bose-Einstein condensate
, 2004 The particle-number fluctuations originated from collective excitations are investigated for a three-dimensional, repulsively interacting Bose-Einstein condensate (BEC) confined in a harmonic trap.

Phase Coherence and Superfluid-Insulator Transition in a Disordered Bose-Einstein Condensate [PDF]
, 2008 We have studied the effects of a disordered optical potential on the transport and phase coherence of a Bose-Einstein condensate (BEC) of 7Li atoms. At moderate disorder strengths (V_D), we observe inhibited transport and damping of dipole excitations ...

Modification of scattering lengths via magnetic dipole-dipole interactions
, 2006 We propose a new mechanism for tuning an atomic s-wave scattering length. The effect is caused by virtual transitions between different Zeeman sublevels via magnetic dipole-dipole interactions. These transitions give rise to an effective potential, which,

Spontaneous Circulation in Ground-State Spinor Dipolar Bose-Einstein Condensates
, 2006 We report on a study of the spin-1 ferromagnetic Bose-Einstein condensate with magnetic dipole-dipole interactions. By solving the non-local Gross-Pitaevskii equations for this system, we find three ground-state phases.

Linear "ship waves" generated in stationary flow of a Bose-Einstein condensate past an obstacle [PDF]
, 2006 Using stationary solutions of the linearized two-dimensional Gross-Pitaevskii equation, we describe the ``ship wave'' pattern occurring in the supersonic flow of a Bose-Einstein condensate past an obstacle.

Counterflow Quantum Turbulence and the Instability in Two-component Bose-Einstein Condensates
, 2010 We theoretically study the nonlinear dynamics of the instability of counter-superflow in two miscible Bose-Einstein condensates. The condensates become unstable when the relative velocity exceeds a critical value, which is called counter-superflow ...

Bose-Einstein Condensation in the Relativistic Ideal Bose Gas
, 2007 The Bose-Einstein condensation (BEC) critical temperature in a relativistic ideal Bose gas of identical bosons, with and without the antibosons expected to be pair-produced abundantly at sufficiently hot temperatures, is exactly calculated for all boson ...
