Crystallized merons and inverted merons in the condensation of spin-1 Bose gases with spin-orbit coupling
arXiv:1111.6338 · doi:10.1103/PhysRevA.86.023601
Abstract
The non-equilibrium dynamics of a rapidly quenched spin-1 Bose gas with spin-orbit coupling is studied. By solving the stochastic projected Gross-Pitaevskii equation, we show that crystallization of merons can occur in a spinor condensate of ^{87}Rb. Analytic form and stability of the crystal structure are given. Likewise, inverted merons can be created in a spin-polarized spinor condensate of ^{23}Na. Our studies provide a chance to explore the fundamental properties of meron-like matter.
