Resonant Raman scattering of single molecules under strong cavity coupling and ultrastrong optomechanical coupling in plasmonic resonators: phonon-dressed polaritons
Stephen Hughes, Alessio Settineri, Salvatore Savasta +1
Plasmonic dimer cavities can induce extreme electric-field hot spots that allow one to access ultrastrong coupling regimes using Raman-type spectroscopy on single vibrating molecul…
Dissipative state transfer and Maxwell's demon in single quantum trajectories: Excitation transfer between two noninteracting qubits via unbalanced dissipation rates
Fabrizio Minganti, Vincenzo Macrì, Alessio Settineri +2
We introduce a protocol to transfer excitations between two noninteracting qubits via purely dissipative processes (i.e., in the Lindblad master equation there is no coherent inter…
Gauge Principle and Gauge Invariance in Two-Level Systems
Salvatore Savasta, Omar Di Stefano, Alessio Settineri +3
The quantum Rabi model is a widespread description of the coupling between a two-level system and a quantized single mode of an electromagnetic resonator. Issues about this model's…
Gauge invariance of the Dicke and Hopfield models
Luigi Garziano, Alessio Settineri, Omar Di Stefano +2
The Dicke model, which describes the dipolar coupling between N two-level atoms and a quantized electromagnetic field, seemingly violates gauge invariance in the presence of ultras…
Conversion of Mechanical Noise into Correlated Photon Pairs: Dynamical Casimir effect from an incoherent mechanical drive
Alessio Settineri, Vincenzo Macrì, Luigi Garziano +3
We show that the dynamical Casimir effect in an optomechanical system can be achieved under incoherent mechanical pumping. We adopt a fully quantum-mechanical approach for both the…
Dissipation and Thermal Noise in Hybrid Quantum Systems in the Ultrastrong Coupling Regime
Alessio Settineri, Vincenzo Macrì, Alessandro Ridolfo +4
The interaction among the components of a hybrid quantum system is often neglected when considering the coupling of these components to an environment. However, if the interaction…
