Dissipation of the Rabi model beyond the rotating wave approximation: Quasi-degenerate qubit and ultra-strong coupling

Shantanu Agarwal, Sayed M. Hashemi Rafsanjani, Joseph H. Eberly

Environmental influences on the dynamics of a coupled qubit-oscillator system are studied analytically. We investigate the case of a quasi-degenerate qubit within the ultra-strong…
