论文摘要
分别研究了从高斯井和高斯屏障中的玻色子凝结物（BEC）的散射。我们比较了在存在和没有PT对称电位的情况下，比较了从高斯障碍物中散射的分析结果和数值结果。而且我们发现，由于ANSATZ的变分参数数量有限，因此复杂的Ginzburg-Landau方程（CGLE）方法具有局限性。我们还发现，PT对称电势的存在控制了BEC通过高斯障碍物的反射和透射通量。
The scattering of a Bose-Einstein Condensate (BEC) from a Gaussian well and Gaussian barrier is investigated over a wide range of depths and heights, respectively. We compare analytical and numerical results for a BEC scattering from Gaussian Obstacles, both in the presence and in the absence of PT-symmetric potential. And we find out that the Complex Ginzburg-Landau Equation (CGLE) method has limitations due to the limited number of variational parameters of the ansatz. We also find that the presence of the PT-symmetric potential controls the reflection and the transmission flux of the BEC through the Gaussian Obstacle.
