Efficient and stable diffusion generated methods for ground state computation in Bose--Einstein condensates
Jing Guo, Yongyong Cai, Dong Wang
This paper investigates numerical methods for approximating the ground state of Bose--Einstein condensates (BECs) by introducing two relaxed formulations of the Gross--Pitaevskii e…

Computing optimal partition problems via Lagrange multiplier approach
Qing Cheng, Jing Guo, Dong Wang
In this paper, we consider numerical approximations for the optimal partition problem using Lagrange multipliers. By rewriting it into constrained gradient flows, three and four st…
