利用原子物质波的时间反演实现Loschillo冷却

Loschmidt cooling by time reversal of atomic matter waves

J. Martin, B. Georgeot, D. L. Shepelyansky

摘要:

我们提出了一个实验方案,它允许实现超冷原子在量子混沌状态下的物质波的近似时间反演。我们表明,一个显着的一部分原子返回到原来的状态,在同一时间冷却了几个数量级。我们给出了广泛的数值模拟支持这种效果的理论描述。所提出的方案可以实现与现有的实验装置。

英文摘要:

We propose an experimental scheme which allows to realize approximate time reversal of matter waves for ultracold atoms in the regime of quantum chaos. We show that a significant fraction of the atoms return back to their original state, being at the same time cooled down by several orders of magnitude. We give a theoretical description of this effect supported by extensive numerical simulations. The proposed scheme can be implemented with existing experimental setups.
