The Rabi model plays a fundamental role in understanding light-matter interaction. It reduces to the Jaynes-Cummings model via the rotating-wave approximation, which is applicable only to the cases of near resonance and weak coupling. However, recent experimental breakthroughs in upgrading light-matter coupling order require understanding the physics of the full quantum Rabi model (QRM). Despite the fact that its integrability and energy spectra have been exactly obtained, the challenge to… 
Fundamental Models in the Light–Matter Interaction: Quantum Phase Transitions and the Polaron Picture
The light–matter interaction not only is ubiquitous in nature but also can be simulated in various artificial systems. Besides the tunability of artificial quantum systems, the experimental access to
Quantum phase transition and spontaneous symmetry breaking in a nonlinear quantum Rabi model
The experimental advance on light-matter interaction into strong couplings has invalidated Jaynes-Cummings model and brought quantum Rabi model (QRM) to more relevance. The QRM only involves linear
Studies on the Rabi Model
We present our recent studies on the quantum Rabi model (QRM). Firstly, by using a variational wave function, which facilitates to extract physics in entire parameter regime with high accuracy, we
First-order and continuous quantum phase transitions in the anisotropic quantum Rabi-Stark model
We study the anisotropic Rabi-Stark model by the Bogoliubov operators approach. Transcendental functions responsible for the exact solutions are derived, which zeros produce the energy spectra. The
The mixed quantum Rabi model
The analytical exact solutions to the mixed quantum Rabi model (QRM) including both one- and two-photon terms are found by using Bogoliubov operators. Transcendental functions in terms of 4 × 4
Polaron picture of the two-photon quantum Rabi model
We employ a polaron picture to investigate the properties of the two-photon quantum Rabi model (QRM), which describes a two-level or spin-half system coupled with a single bosonic mode by a
Entanglement resonance in the asymmetric quantum Rabi model
We investigate the entanglement features in the interacting system of a quantized optical field and a two-level system which is statically driven, known as the asymmetric quantum Rabi model (AsymQRM).
Generalized quantum Rabi model with both one- and two-photon terms: A concise analytical study
A generalized quantum Rabi Hamiltonian with both one- and two-photon terms has emerged in the circuit quantum electrodynamics system for a decade. The usual parity symmetry is broken naturally in the
The asymmetric quantum Rabi model in the polaron picture
The concept of the polaron in condensed matter physics has been extended to the Rabi model, where polarons resulting from the coupling between a two-level system and single-mode photons represent two
Landau-Zener-Stueckelberg interferometry with driving fields in the quantum regime
We analyze the dynamics of a two-level quantum system (TLS) under the influence of a strong sinusoidal driving signal whose origin is the interaction of the two-level system with a quantum field. In
