Abstract

We show that the entropy of entanglement is sensitive to the coherent quantum phase transition between normal and super-radiant regions of a system of a finite number of three-level atoms interacting in a dipolar approximation with a one-mode electromagnetic field. The atoms are treated as semi-distinguishable using different cooperation numbers and representations of SU(3), variables which are relevant to the sensitivity of the entropy with the transition. The results are computed for all three possible configurations ( Ξ , Λ and ) of the three-level atoms.

摘要

我们表明，对于有限数量的三能级原子与单模电磁场在偶极近似下相互作用的系统，纠缠熵对正常区域和超辐射区域之间的相干量子相变敏感。使用不同的合作数和SU(3)表示将原子视为半可区分的，这些变量与熵随相变的敏感性相关。针对三能级原子的所有三种可能构型（Ξ、Λ和 ）计算了结果。
