Exotic ground states of a spin–orbit-coupled spinor Bose–Einstein condensate trapped by a toroidal potential

Ping Peng, Guan-Qiang Li, Wen‐Li Yang +1 more

Abstract The ground-state properties of a spin–orbit-coupled spin-1 Bose–Einstein condensate (BEC) in a toroidal trap are investigated. The exotic ground states, such as the necklace state, the persistent flow and even the vortex state, for the three components in the system are induced by adjustable external parameters. It is found that the petal number of the necklace states is increased with increasing the intensity of the spin–orbit coupling (SOC), and the anisotropy of the SOC can be used to control the structure of the ground states. The rotation of the condensate induced by the external field makes the densities of the three components asymmetric and tends to transform the necklace state to the persistent flow. The radius of the toroidal potential is another degree of freedom for manipulating the necklace state. In addition, the transition between the necklace state and the vortex, intermediated by the persistent flow, can be controlled by the ratio of the density-density and spin-exchange interactions. All of above results enrich our knowledge about the properties of the ground states of spin-1 BEC trapped in the toroidal trap.

Ground States of Dipolar Spin–Orbit-Coupled Bose–Einstein Condensates in a Toroidal Trap

Hui Yang, Qingbo Wang, Linghua Wen

We investigate the ground-state structures of dipolar spin-orbit-coupled Bose-Einstein condensates in a toroidal trap. Combined effects of dipole-dipole interaction (DDI) and spin-orbit coupling (SOC) on the ground states of the system are discussed. A ground-state phase diagram is obtained as a function of the SOC and DDI strengths. As two new degrees of freedom, the DDI and SOC can be used to obtain the desired ground-state phases and to control the phase transition between various ground states. In particular, the system displays exotic topological structures and spin textures, such as half-quantum vortex, vortex string, vortex necklace, complex vortex lattice including giant vortex and hidden antivortex chains, different skyrmions, meron (half-skyrmion)-antimeron (half-antiskyrmion) necklace, and composite meron-antimeron lattice.
