New symmetry in the Rabi model    [PDF]

Bartlomiej Gardas, Jerzy Dajka

It is recognized that, apart from the total energy conservation, there is a nonlocal $\mathbb{Z}_2$ symmetry in the Rabi model represented by a generalized parity commuting with the Rabi Hamiltonian. Conditions for the existence of this observable, its form and explicit construction are presented.
