论文摘要
我们提出了一个替代实现的替代实现，该方程适用于原子玻色的数值建模，原子 - 玻色子凝结物被困在环形形状的电势中。我们提出了一个准确有效的方案，以评估所需的矩阵元素并计算物质波场的时间演变。我们分析了开发的环形陷阱中开发的平衡和非平衡溶液的稳定性和准确性，其额外的屏障电位与最近的实验实现相对应。
We propose an alternative implementation of the Projected Gross-Pitaevskki equation adapted for numerical modeling of the atomic Bose-Einstein condensate trapped in a toroidally-shaped potential. We present an accurate and efficient scheme to evaluate the required matrix elements and calculate time evolution of the matter wave field. We analyze the stability and accuracy of the developed method for equilibrium and nonequilibrium solutions in a ring-shaped trap with additional barrier potential corresponding to recent experimental realizations.
