论文摘要
我们将各种物种的负载原子的效率从冷集合中建立到一个维度的光学晶格中，并考虑到初始云温度和大小，影响捕获电位的晶格激光特性和原子参数。随机采样和动力学演化用于模拟转移，从而导致了不同陷阱深度和轮廓的转移效率的估计。追踪原子的运动还可以评估晶格中平衡温度和位点占用率。该模拟比较了许多实验结果，并用于计算给定光学功率的最佳晶格waist与云-radius的比率。
We model the efficiency of loading atoms of various species into a one dimensional optical lattice from a cold ensemble taking into account the initial cloud temperature and size, the lattice laser properties affecting the trapping potential, and atomic parameters. Stochastic sampling and dynamical evolution are used to simulate the transfer, leading to estimates of transfer efficiency for varying trap depth and profile. Tracing the motion of the atoms also enables the evaluation of the equilibrium temperature and site occupancy in the lattice. The simulation compares favourably against a number of experimental results, and is used to compute an optimum lattice-waist to cloud-radius ratio for a given optical power.
