Novel interactions beyond the four known fundamental forces in nature (electromagnetic,
gravitational, strong and weak interactions), may arise due to" new physics" beyond the …

The quantum Rabi model (QRM) with linear coupling between light mode and qubit exhibits
the analog of a second-order phase transition for vanishing mode frequency which allows …

The superradiant phase transition (SPT) has been widely studied in cavity quantum
electrodynamics (CQED). However, this SPT is still subject to ongoing debates due to the no …

Quadratic light-matter interactions are nonlinear couplings such that quantum emitters
interact with photonic or phononic modes exclusively via the exchange of excitation pairs …

The asymmetric quantum Rabi model (AQRM) has a broken Z 2 symmetry, with generally a
nondegenerate eigenvalue spectrum. In some special cases where the asymmetric …

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 …

The quantum Rabi model (QRM) is a fundamental model for light-matter interactions. A
fascinating feature of the QRM is that it manifests a quantum phase transition which is …

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 …

Quantum Rabi model (QRM) is fascinating not only because of its broad relevance but also
due to its few-body quantum phase transition. In practice, both the bias and the nonlinear …

Abstract The Jaynes–Cummings Model (JCM) is a fundamental model and building block for
light‐matter interactions, quantum information and quantum computation. The present work …
