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…
Gauge-Independent Emission Spectra and Quantum Correlations in the Ultrastrong Coupling Regime of Open System Cavity-QED
Will Salmon, Chris Gustin, Alessio Settineri +5
A quantum dipole interacting with an optical cavity is one of the key models in cavity quantum electrodynamics (cavity-QED). To treat this system theoretically, the typical approac…
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 Principle and Gauge Invariance in Quantum Two-Level Systems
Salvatore Savasta, Omar Di Stefano, Alessio Settineri +3
The quantum Rabi model is a widespread description for the coupling between a two-level system and a quantized single mode of an electromagnetic resonator. Issues about this model'…
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…
Gauge freedom, quantum measurements, and time-dependent interactions in cavity and circuit QED
Alessio Settineri, Omar Di Stefano, David Zueco +3
The interaction between the electromagnetic field inside a cavity and natural or artificial atoms has played a crucial role in developing our understanding of light-matter interact…
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…
Near-field imaging of surface-plasmon vortex-modes around a single elliptical nanohole in a gold film
Claudia Triolo, Salvatore Savasta, Alessio Settineri +4
We present scanning near-field images of surface plasmon modes around a single elliptical nanohole in 88 nm thick Au film. We find that rotating surface plasmon vortex modes carryi…
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…
Interaction of Mechanical Oscillators Mediated by the Exchange of Virtual Photon Pairs
Omar Di Stefano, Alessio Settineri, Vincenzo Macrì +5
Two close parallel mirrors attract due to a small force (Casimir effect) originating from the electromagnetic quantum vacuum uctuations of the electromagnetic field. These vacuum u…
