The quantum Rabi model for two qubits

We study a system composed of two nonidentical qubits coupled to a single-mode quantum field. We calculate the spectra of the system in the deep-strong-coupling regime via perturbation theory up to second-order corrections and show that it converges to two forced oscillator chains for cases well int...
