Dissipative phase transitions and chaos in two-photon driven quantum optomechanics

Giovanni Bragadin, Filippo Ferrari, Lorenzo Fioroni +4

We investigate nonequilibrium criticality and chaos in a two-photon-driven optomechanical system. The parametric drive preserves a discrete symmetry of the optical f…

Density Wave Ordering with Disordered Ultracold Fermions in Optical Cavities

Óscar Rios Alves, Filippo Ferrari, Lorenzo Fioroni +2

We investigate the interplay between cavity-induced density-wave ordering and controllable disorder in a trapped two-dimensional gas of ultracold fermions. The atoms are dispersive…

Floquet Dissipative Phase Transitions

Alberto Mercurio, Vincenzo Macrì, Filippo Ferrari +2

Dissipative phase transitions (DPTs) are traditionally characterized through the spectrum of a time-independent Liouvillian superoperator. However, this definition does not apply t…

From Few to Many Emitters Cavity QED: Energy Levels and Emission Spectra From Weak to Deep-Strong Coupling

Andrea Zappalá, Alberto Mercurio, Daniele Lamberto +3

We present a systematic study of the properties of systems composed of two-level quantum emitters coupled to a single cavity mode, for light-matter interaction strengths rangin…

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…

Nonperturbative cavity quantum electrodynamics: is the Jaynes-Cummings model still relevant?

Daniele De Bernardis, Alberto Mercurio, Simone De Liberato

In this tutorial review, we briefly discuss the role that the Jaynes-Cummings model occupies in present-day research in cavity quantum electrodynamics with a particular focus on th…

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…

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…

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…

Photon condensation, Van Vleck paramagnetism, and chiral cavities

Alberto Mercurio, Gian Marcello Andolina, Francesco M. D. Pellegrino +6

We introduce a gauge-invariant model of planar, square molecules coupled to a quantized spatially-varying cavity electromagnetic vector potential A(r). Specifically, we choose a te…

Flying atom back-reaction and mechanically generated photons from vacuum

Alberto Mercurio, Simone De Liberato, Franco Nori +2

We investigate the dynamics of a two-level atom flying through a photonic cavity when the light-matter interaction is in the ultrastrong coupling regime. We adopt a closed full qua…

Pure Dephasing of Light-Matter Systems in the Ultrastrong and Deep-Strong Coupling Regimes

Alberto Mercurio, Shilan Abo, Fabio Mauceri +5

Pure dephasing originates from the non-dissipative information exchange between quantum systems and environments, and plays a key-role in both spectroscopy and quantum information…
