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…
Strong coupling between a single-photon and a two-photon Fock state
Shuai-Peng Wang, Alberto Mercurio, Alessandro Ridolfo +9
The realization of strong nonlinear coupling between single photons has been a long-standing goal in quantum optics and quantum information science, promising wide impact applicati…
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…
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…
Circuit QED Spectra in the Ultrastrong Coupling Regime: How They Differ from Cavity QED
Samuel Napoli, Alberto Mercurio, Daniele Lamberto +3
Cavity quantum electrodynamics (QED) studies the interaction between resonator-confined radiation and natural atoms or other formally equivalent quantum excitations, under conditio…
Phonon Pumping by Modulating the Ultrastrong Vacuum
Fabrizio Minganti, Alberto Mercurio, Fabio Mauceri +3
The vacuum (i.e., the ground state) of a system in ultrastrong light-matter coupling contains particles that cannot be emitted without any dynamical perturbation and is thus called…
