摘要
在GPE方程的基础上添加了一个耗散项-1/2γcψ,用来分析双势阱模型的Josephson振荡中的阻尼现象,并得出：凝聚态粒子总数及Josephson振动的振幅随时间呈指数衰减。
Abstract
In this paper,we add a dissipative term-1/2γcψ to the GPE equation,and use it to analyze the damping effect of Josephson junction in the double-well trap model,and find that the total number of condensation and the amplitude of Josephson junction damp change along with time in an exponent declining way.
