Computing the ground state solution of Bose-Einstein condensations by finite element method

HUA Dong-ying,QIU Jing-liang(School of Applied Sciences,Beijing Information Science and Technology University,Beijing 100192,China)  
The computational cost of computing the ground state solution of the three dimensional Bose-Einstein condensations(BECs) is generally very high,we reduce the three dimensional problem with the radial symmetry to the one dimensional cigar-shaped problem.The finite element imaginary method is presented and then the nonlinear term is linearized.The numerical examples show that our numerical method has optimal second-order accuracy and the computational cost is low.
