论文摘要
我们在这里提供了三个平行的OpenMP Fortran 90/95程序,用于计算基础状态和用各向异性旋转轨道(SO)耦合的旋转2 Bose-Einstein冷凝物(BECS)的动态,通过求解五个使用五个耦合的GROSS-PITAEVSKIIIEEQUATION的耦合。根据问题的性质,我们没有任何普遍性的损失,我们采用了跨越三,二或一维空间的笛卡尔网格来进行数值离散。为了说明包装的真实性,无论如何,我们都将完整均值模型的数值基态解决方案与简化标量模型的基础解决方案进行了比较。这两组结果表现出了极好的一致性,特别是通过地面的平衡密度,能量和化学势。我们还为OpenMP性能参数(例如加速和三个代码的效率)提供了测试结果。
We provide here a set of three OpenMP parallelized FORTRAN 90/95 programs to compute the ground states and the dynamics of trapped spin-2 Bose-Einstein condensates (BECs) with anisotropic spin-orbit (SO) coupling by solving a set of five coupled Gross-Pitaevskii equations using a time-splitting Fourier spectral method. Depending on the nature of the problem, without any loss of generality, we have employed the Cartesian grid spanning either three-, two-, or one-dimensional space for numerical discretization. To illustrate the veracity of the package, wherever feasible, we have compared the numerical ground state solutions of the full mean-field model with those from the simplified scalar models. The two set of results show excellent agreement, in particular, through the equilibrium density profiles, energies and chemical potentials of the ground-states. We have also presented test results for OpenMP performance parameters like speedup and the efficiency of the three codes.
