Ultrastrong coupling between light and matter has, in the past decade, transitioned from a
theoretical idea to an experimental reality. It is a new regime of quantum light–matter …

Recent experiments have demonstrated that light and matter can mix together to an extreme
degree, and previously uncharted regimes of light-matter interactions are currently being …

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

The quantum Rabi model describing the fundamental interaction between light and matter is
a cornerstone of quantum physics. It predicts exotic phenomena like quantum phase …

We propose a superconducting circuit to implement a two-photon quantum Rabi model in a
solid-state device, where a qubit and a resonator are coupled by a two-photon interaction …

The interaction of light and matter at the single-photon level is of central importance in
various fields of physics, including, eg, condensed matter physics, astronomy, quantum …

The controllability of current quantum technologies allows one to implement spin-boson
models where two-photon couplings are the dominating terms of light-matter interaction. In …

The coupling of a two-level system with an electromagnetic field, whose fully quantized
version is the quantum Rabi model, is among the central topics of quantum physics. When …

We propose a digital-analog quantum simulation of generalized Dicke models with
superconducting circuits, including Fermi-Bose condensates, biased and pulsed Dicke …

We study the nonlinear dynamics of trapped-ion models far away from the Lamb-Dicke
regime. This nonlinearity induces a blockade on the propagation of quantum information …
