声在两种玻色-爱因斯坦凝聚体中的传播

Propagation of Sound in Two-Species Bose-Einstein Condensates

D. Lima, P. Borckmans, G. Dewel

摘要:

研究了零声在两组分互穿玻色-爱因斯坦凝聚体中的传播。在非常细长的云,这种传播被证明是基本上是一维的。我们还提出了一维数值实验,表现出存在两种不同的声音脉冲的速度与理论预测一致。

英文摘要:

We investigate the propagation of zero sound in two-species interpenetrating Bose-Einstein condensates. In very elongated clouds, this propagation is shown to be essentially one-dimensional. We also present 1D numerical experiments that exhibit the existence of two different sound pulses with velocities consistent with the theoretical predictions.
