【摘要】 在引入参数下研究了5种不同边界条件下一维理想玻色爱因斯坦凝聚体中杂质间的类Casimir力,给出了这些边界下类Casimir力的通式.发现类Casimir力随杂质间距离增大而衰减,力的性质因边界不同表现为吸引或排斥.这说明当改变杂质满足的边界条件时可以改变类Casimir力的性质.同时,类Casimir力随玻色子质量的变化趋势也与边界条件有关.更多还原

【Abstract】 By introducing a new parameter,this paper concluded an usual expression to calculate the Casimir-like effect between contaminants in the one-dimensional ideal Bose-Einstein condensates with five different boundary conditions.It is found that these effect acting on contaminants all decay with distance but qualitatively different:some repulsive,others attractive.That depends on the boundary conditions imposed.This means we can modify the repulsive or attractive nature of effect acting on contaminants by changing the boundary condition that contaminants satisfied.At the same time,the figure that Casimir-like effect varies with the mass of boson is also sensitive to boundary condition.更多还原
