论文摘要
我们介绍了在手性波导附近的原子的量子光学问题与广义量子兔模型之间的直接映射，并讨论了在超声偶联体中，光子结构中原子链自组织的原子链的自组织与dicke-like量子变速器之间的类比。我们扩展了具有$ \ Mathbb {Z} _3 $而不是奇偶校验$ \ Mathbb {z} _2 $对称的系统的超级相位转换的类别，并演示了这些系统中多组件Schrodinger cat状态的出现。
We present a direct mapping between the quantum optomechanical problem of the atoms harmonically trapped in the vicinity of a chiral waveguide and a generalized quantum Rabi model and discuss the analogy between the self-organization of atomic chains in photonic structures and Dicke-like quantum phase transitions in the ultrastrong coupling regime. We extend the class of the superradiant phase transitions for the systems possessing $\mathbb{Z}_3$ rather than parity $\mathbb{Z}_2$ symmetry and demonstrate the emergence of the multicomponent Schrodinger cat ground states in these systems.
