Ground state study of spin-orbit-coupled Bose-Einstein condensates in concentrical dual-ring potential well
Chen Guang-pin
The ground state structure of spin-orbit-coupled Bose-Einstein condensates in concentrical dual-ring potential well is studied,with changing of the spin-orbit-coupled,multiple ground state structures are appearing in the coupled system. If the spin-orbit-coupled is added increasingly only in one direction,inhomogeneous distribution of the azimuthal phase separation is appeared in the ground state density,however it is still the stating wave from the phase graph showing. The other spin-orbitcoupled strength is added increasingly in vertical direction until the same with the original direction,when the isotropy of spinorbit-coupled is shaped,homogeneous distribution of the azimuthal phase separation is appeared gradually in the ground state density. Investigation from phase diagram shows that a large number of vortexes in ground state system are generated by the function of isotropy spin-orbit-coupled.
