一维二能级原子链的次辐射态理论

Theory of Subradiant States of a One-Dimensional Two-Level Atom Chain

Yu-Xiang Zhang, Klaus Mølmer

摘要:

最近,人们发现耦合到光模的一维二能级原子链的次辐射态具有服从普适标度的衰减速率,并且发现了多重激发次辐射态的一种意想不到的费米子性质。在这封信中,我们从理论上得到了单激发次辐射态,并通过消除超辐射模,我们证明了多激发次辐射态与解释费米子行为的Lieb-Liniger模型的Tonks-Girardeau极限之间的关系。此外,我们确定了一个新的家庭的状态与相关性不同的费米子的反。

英文摘要:

Recently, the subradiant states of one-dimensional two-level atom chains coupled to light modes were found to have decay rates obeying a universal scaling, and an unexpected fermionic character of the multiply-excited subradiant states was discovered. In this Letter, we theoretically obtain the singly-excited subradiant states, and by eliminating the superradiant modes, we demonstrate a relation between the multiply-excited subradiant states and the Tonks-Girardeau limit of the Lieb-Liniger model which explains the fermionic behavior. In addition, we identify a new family of states with correlations different from the fermionic ansatz.
