Stable Skyrmions in SU(2) Gauged Bose-Einstein Condensates

, 2012
We demonstrate that the three-dimensional Skyrmion, which has remained elusive so far, spontaneously appears as the ground state of $SU$(2) symmetric Bose-Einstein condensates coupled with a non-Abelian gauge field. The gauge field is a three-dimensional

Solitary waves of Bose-Einstein condensed atoms confined in finite rings

, 2010
Motivated by recent progress in trapping Bose-Einstein condensed atoms in toroidal potentials, we examine solitary-wave solutions of the nonlinear Schr\"odinger equation subject to periodic boundary conditions.

A Sawtooth Permanent Magnetic Lattice for Ultracold Atoms and BECs

, 2011
We propose a new permanent magnetic lattice for creating periodic arrays of Ioffe-Pritchard permanent magnetic microtraps for holding and controlling ultracold atoms and Bose-Einstein condensates (BECs).

Particle fluctuations in nonuniform and trapped Bose gases

, 2009
The problem of particle fluctuations in arbitrary nonuniform systems with Bose-Einstein condensate is considered. This includes the case of trapped Bose atoms. It is shown that the correct description of particle fluctuations for any nonuniform system of

A strongly interacting Bose gas: Nozi\`eres and Schmitt-Rink theory and beyond

, 2009
We calculate the critical temperature for Bose-Einstein condensation in a gas of bosonic atoms across a Feshbach resonance, and show how medium effects at negative scattering lengths give rise to pairs reminiscent of the ones responsible for fermionic ...

Study of stability of relativistic ideal Bose-Einstein condensates

, 2012
A relativistic complex scalar boson field at finite temperature $T$ is examined below its critical Bose-Einstein condensation temperature. It is shown that at the same $T$ the state with antibosons has higher entropy, lower Helmholtz free energy and ...

Manipulating the momentum state of a condensate by sequences of standing wave pulses

, 2011
We analyze the effects of sequences of standing wave pulses on a Bose-Einstein condensate (BEC). Experimental observations are in good agreement with a numerical simulation based on the band structure theory in the optical lattice.

Skyrmion dynamics and disintegration in a spin-1 Bose-Einstein condensate

, 2012
Dynamics of skyrmionic spin texture in the spin-1 Bose-Einstein condensate is examined by analytical and numerical means. We show the skyrmion (coreless vortex) to be inherently unstable in the sense that the state initially prepared purely within the ...

Mode interference in quantum joint probabilities for multimode Bose-condensed systems

, 2013
The method of defining quantum joint probabilities of two events is applied to a multimode system of trapped Bose-condensed atoms. The coherent modes are generated by modulating the trapping potential with an alternating field with a frequency in ...
