Gap solitons of spin-orbit-coupled Bose-Einstein condensates in PT periodic potential
文献摘要：
We numerically investigate the gap solitons in Bose-Einstein condensates(BECs)with spin-orbit coupling(SOC)in the parity-time(PT)-symmetric periodic potential.We find that the depths and periods of the imaginary lattice have an important influence on the shape and stability of these single-peak gap solitons and double-peak gap solitons in the first band gap.The dynamics of these gap solitons are checked by the split-time-step Crank-Nicolson method.It is proved that the depths of the imaginary part of the PT-symmetric periodic potential gradually increase,and the gap solitons become unstable.But the different periods of imaginary part hardly affect the stability of the gap solitons in the corresponding parameter interval.
