Solitons in a trapped spin-1 atomic condensate
Wenxian Zhang, Ö. E. Müstecaplıoğlu, L. You
We numerically investigate a particular type of spin solitons inside a trapped atomic spin-1 Bose-Einstein condensate (BEC) with ferromagnetic interactions. Within the mean field t…
Effective size of a trapped atomic Bose gas
Wenxian Zhang, Z. Xu, L. You
We investigate the temperature-dependent effective size of a trapped interacting atomic Bose gas within a mean field theory approximation. The sudden shrinking of the average lengt…
Dynamical instability and domain formation in a spin-1 Bose condensate
Wenxian Zhang, D. L. Zhou, M. -S. Chang +2
We interpret the recently observed spatial domain formation in spin-1 atomic condensates as a result of dynamical instability. Within the mean field theory, a homogeneous condensat…
Coherent spinor dynamics in a spin-1 Bose condensate
Ming-Shien Chang, Qishu Qin, Wenxian Zhang +2
Collisions in a thermal gas are perceived as random or incoherent as a consequence of the large numbers of initial and final quantum states accessible to the system. In a quantum g…
Coherent spin mixing dynamics in a spin-1 atomic condensate
Wenxian Zhang, D. L. Zhou, M. -S. Chang +2
We study the coherent off-equilibrium spin mixing inside an atomic condensate. Using mean field theory and adopting the single spatial mode approximation (SMA), the condensate spin…
An effective quasi-one-dimensional description of a spin-1 atomic condensate
Wenxian Zhang, L. You
Within the mean field theory we extend the effective quasi-1D non-polynomial Schrödinger equation (NPSE) approach to the description of a spin-1 atomic condensate in a tight radial…
