论文摘要
在这里，我们提出了简单有效的数值方案，以研究Spin-1 Bose-Einstein冷凝物（BEC）与自旋轨道（SO）耦合的静态和动态特性，通过求解三个耦合的GROSS-PITAEVSKII方程（CGPE）在三个，Quasi-Two和Quasi-Two和Quasi-one Dimensions Systems中。我们提供一组在Fortran 90/95编程语言中开发的三个代码，并定义了虚构和实时传播的“ {\ em option}”。我们介绍了基态能量，化学势和成分密度的数值结果，并与文献的可用结果进行了比较。对于具有和不耦合的铁磁磁性旋转1 BEC，均给出了结果。为了提高计算速度，所有代码都有OpenMP并行化的选项。我们还介绍了具有虚构和实时传播的三个代码的OpenMP并行化的加速和效率的结果。
Here, we present simple and efficient numerical scheme to study static and dynamic properties of spin-1 Bose-Einstein condensates (BECs) with spin-orbit (SO) coupling by solving three coupled Gross-Pitaevskii equations (CGPEs) in three-, quasi-two and quasi-one dimensional systems. We provide a set of three codes developed in FORTRAN 90/95 programming language with user defined '{\em option}' of imaginary and real-time propagation. We present the numerical results for energy, chemical potentials, and component densities for the ground state and compare with the available results from the literature. The results are presented for both the ferromagnetic and antiferromagnetic spin-1 BECs with and without SO coupling. To improve the computational speed, all the codes have the option of OpenMP parallelization. We have also presented the results for speedup and efficiency of OpenMP parallelization for the three codes with both imaginary and real-time propagation.
