FORTRESS: FORTRAN programs to solve coupled Gross-Pitaevskii equations for spin-orbit coupled spin-f Bose-Einstein condensate with spin f = 1 or 2

We provide here the updated versions of OpenMP parallelized FORTRAN 90/95 programs to numerically study the ground states and/or the dynamics of homogeneous or trapped spin-1 or spin-2 Bose-Einstein condensates (BECs) with anisotropic spin-orbit (SO) coupling. The coupled sets of three or five Gross-Pitaevskii (GP) equations, respectively, for a spin-1 or a spin-2 Bose-Einstein condensate (BEC) are solved using a time-splitting Fourier spectral method.

本文提供了经更新的OpenMP并行化FORTRAN 90/95程序，用于数值研究各向异性自旋轨道（spin-orbit, SO）耦合的自旋1或自旋2玻色-爱因斯坦凝聚体（Bose-Einstein condensates, BECs）的基态与/或动力学特性，该凝聚体可处于均匀分布或受外势阱束缚的状态。针对自旋1与自旋2玻色-爱因斯坦凝聚体，分别采用3组与5组耦合的格罗斯-皮塔耶夫斯基（Gross-Pitaevskii, GP）方程进行建模，并通过时间分裂傅里叶谱方法完成求解。
