Dynamics Of Rotating Spin-Orbit-Coupled Bose-Einstein Condensates In A Quasicrystalline Optical Lattice

We investigate the dynamics of rotating pseudo-spin-1/2 Bose-Einstein condensates (BECs) with Rashba spin-orbit coupling (SOC) in a quasicrystalline optical lattice (QOL). For given parameters, the system evolves from an initial heliciform-stripe phase into a final visible vortex necklace with a giant vortex and a hidden vortex necklace. Simultaneously, the corresponding spin texture undergoes a transition from a meron-antimeron pair to a half-antiskyrmion necklace. During the dynamic evolution process, the angular momentu m increases gradually, and then approaches to a convergent value. Furthermore, typical quantu m phases of rotating two-component BECs with SOC in different external potentials are summarized .
