Renormalization and Low-Energy Effective Models in Cavity and Circuit QED

Daniele Lamberto, Alberto Mercurio, Omar Di Stefano +2

The quantum Rabi model (QRM) is a cornerstone in the study of light-matter interactions within cavity and circuit quantum electrodynamics (QED). It effectively captures the dynamic…

Superradiant Quantum Phase Transition in Open Systems: System-Bath Interaction at the Critical Point

Daniele Lamberto, Gabriele Orlando, Salvatore Savasta

The occurrence of a second-order quantum phase transition in the Dicke model is a well-established feature. On the contrary, a comprehensive understanding of the corresponding open…

Quantum Phase Transitions in Many-Dipole Light-Matter Systems

Daniele Lamberto, Omar Di Stefano, Stephen Hughes +2

A potential phase transition between a normal ground state and a photon-condensed ground state in many-dipole light-matter systems is a topic of considerable controversy, exasperat…

Bilateral photon emission from a vibrating mirror and multiphoton entanglement generation

Alberto Mercurio, Enrico Russo, Fabio Mauceri +4

Entanglement plays a crucial role in the development of quantum-enabled devices. One significant objective is the deterministic creation and distribution of entangled states, achie…
