Generalized parity in multi-photon Rabi model
Bartłomiej Gardas, Jerzy Dajka
Quantum multi--photon spin--boson model is considered. We solve an operator Riccati equation associated with that model and present a candidate for a generalized parity operator al…

Initial states of qubit-boson models leading to conserved quantities
Bartlomiej Gardas, Jerzy Dajka
It is possible to prepare a composite qubit-environment system so that its time evolution will guarantee the conservation of a preselected qubit's observable. In general, this obse…

New symmetry in the Rabi model
Bartlomiej Gardas, Jerzy Dajka
It is recognised that, apart from the total energy conservation, there is a nonlocal and a somewhat hidden symmetry in this model. Conditions for the existence of th…
