报告摘要：

In this talk, we will present efficient numerical methods to compute the ground state and dynamics of the rotating dipolar Bose-Einstein condensate. The methods consist of three merits: (i) efficient and accurate numerical methods will be proposed to evaluate the nonlocal dipole-dipole interaction. (ii) a nonlinea conjugate gradient method, accelerated by some well-adapted preconditioners, will be developed to comput the ground states. (iii) a rotating Lagrangian coordinate transformation will be presented to eliminate the rotation term, based on which time splitting spectral methods will be presented to simulate the dynamics.
