From coupled ${\mathbb{Z}}_3$ Rabi models to the ${\mathbb{Z}}_3$ Potts model

Anatoliy I. Lotkov, Valerii K. Kozin, Denis V. Kurlov +2

We study ${\mathbb{Z}}_3$-symmetric Rabi model that describes a three-level system coupled to two bosonic modes. We derive a mapping of the two-mode ${\mathbb{Z}}_3$ Rabi model onto a…
