High-order interactions in quantum optomechanics: fluctuations, dynamics and thermodynamics
Alessandro Ferreri, Vincenzo Macrì, Yoshihiko Hasegawa +1
Quantum optomechanics describes the interaction between a confined field and a fluctuating wall due to radiation pressure. The dynamics of this system is typically understood using…
Limits to the validity of gravitational redshift as a quantum-optical multimode mixer
Nils Leber, Luis Adrián AlanÃs RodrÃguez, Alessandro Ferreri +2
We analyze the domain of validity of a quantum optical model that describes the effects of gravitational redshift on the quantum state of photons that propagate in curved spacetime…
Gravitational redshift of broadband relativistic quantum photons
Alessio Lapponi, Alessandro Ferreri, David Edward Bruschi
We employ linearized quantum gravity to study gravitational redshift of photons in the context of relativistic and quantum physics, where photons interact in flat spacetime with a…
Photon-graviton polarization entanglement induced by a classical electromagnetic wave
Alessandro Ferreri
We study the photon-graviton pair production induced by the propagation of a classical electromagnetic (EM) wave in a Minkowskian spacetime. In our model, the gravitational field i…
Splitting obstructions and invariants in time-reversal symmetric topological insulators
Alessandro Ferreri, Domenico Monaco, Gabriele Peluso
The Fu-Kane-Mele index characterizes two-dimensional time-reversal symmetric topological phases of matter. We shed some light on some features of this index by inves…
Function Based Isolation Forest (FuBIF): A Unifying Framework for Interpretable Isolation-Based Anomaly Detection
Alessio Arcudi, Alessandro Ferreri, Francesco Borsatti +1
Anomaly Detection (AD) is evolving through algorithms capable of identifying outliers in complex datasets. The Isolation Forest (IF), a pivotal AD technique, exhibits adaptability…
