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

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 …

We demonstrate the emergence of nonreciprocal superradiant phase transitions and novel
multicriticality in a cavity quantum electrodynamics system, where a two-level atom interacts …

Present protocols of criticality-enhanced sensing with open quantum sensors assume direct
measurement of the sensor and omit the radiation quanta emitted to the environment …

Quantum phase transitions (QPTs) are usually associated with many-body systems in the
thermodynamic limit when their ground states show abrupt changes at zero temperature with …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

Physical systems close to a quantum phase transition exhibit a divergent susceptibility,
suggesting that an arbitrarily high precision may be achieved by exploiting quantum critical …

Quantum criticality, as a fascinating quantum phenomenon, may provide significant
advantages for quantum sensing. Here we propose a dynamic framework for quantum …
