报告题目：An efficient numerical method to compute the ground state of  rotating dipolar Bose-Einstein Condensates

报告摘要：

(1) In this talk, we will present an efficient numerical method for computing the ground state of the rotating dipolar Bose-Einstein Condensates (BEC).  The method consists two main merits: (i)  efficient and accurate numerical methods will be proposed to evaluate the nonlocal dipole-dipole interaction. (ii) a nonlinear conjugate gradient method, accelerated by some well-adapted preconditioners, will be developed to compute the ground states.  This work is realized in collaboration with Xavier ANTOINE (IECL, Lorraine, France), Antoine LEVITT (Inria, Paris, France) and Yong ZHANG (Tianjin University, Tianjin, China).

(2) Dynamical properties of some physical quantities, including the total mass, energy, center of mass and angular momentum expectation, are presented and confirmed numerically. Interesting dynamical phenomena that are peculiar to the rotating two-component dipolar BECs, such as dynamics of center of mass, quantized vortexlattices dynamics and the collapse dynamics in 3D, are presented.
