A SYMPLECTIC SCHEME ON NUMERICAL STUDY FOR GROSS-PITAEVSKII EQUATION

摘要：

For a Bose-Einstein Condensate placed in a rotating trap and confined in the z axis,a kind of symplectic difference schemes was constructed,which is second order in time and arbitrary order in space to investigate the evolution of vortices of BEC in this paper.First,we look for a steady state solution of the imaginary time G-P equation.Then,we numerically study the vorticess development in real time,starting with the solution in imaginary time as initial value.
