自旋压缩与最大压缩时间

Spin squeezing and maximal-squeezing time

Guang-Ri Jin, Sang Wook Kim

摘要:

研究了类约瑟夫森耦合非线性相互作用模型的自旋压缩,得到了最大压缩的时间尺度。基于两种可精确求解的两粒子和三粒子情形,我们发现最大压缩时间依赖于基态与下一个相邻本征态之间的能级间距。

英文摘要:

Spin squeezing of a nonlinear interaction model with Josephson-like coupling is studied to obtain time scale of maximal squeezing. Based upon two exactly solvable cases for two and three particles, we find that the maximal-squeezing time depends on the level spacing between the ground state and its next neighbor eigenstate.
