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 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 …

Polaritonic chemistry is an interdisciplinary emerging field that presents several challenges
and opportunities in chemistry, physics, and engineering. A systematic review of polaritonic …

Gauge freedom in quantum electrodynamics (QED) outside of textbook regimes is reviewed.
It is emphasized that QED subsystems are defined relative to a choice of gauge. Each …

We propose a physical witness for dynamically detecting topological phase transitions
(TPTs) via an experimentally observable out-of-time-order correlation (OTOC). The …

The interaction between quantized electromagnetic fields in cavities and natural or artificial
atoms has played a crucial role in developing our understanding of light-matter interactions …

Despite significant theoretical efforts devoted to studying the interaction between quantized
light modes and matter, the so-called ultrastrong coupling regime still presents significant …

The prototypical system constituted by a two-level atom interacting with a quantized single-
mode electromagnetic field is described by the quantum Rabi model (QRM). The QRM is …

We show that spontaneous Raman scattering of incident radiation can be observed in cavity-
QED systems without external enhancement or coupling to any vibrational degree of …

The control of the interaction between quantum emitters using nanophotonic structures
holds great promise for quantum technology applications, while its theoretical description for …
