Ultrastrong Magnon-Photon Coupling Achieved by Magnetic Films in Contact with Superconducting Resonators
Alberto Ghirri, Claudio Bonizzoni, Maksut Maksutoglu +4
Coherent coupling between spin wave excitations (magnons) and microwave photons in a cavity may disclose new paths to unconventional phenomena as well as for novel applications. He…
Revealing higher-order light and matter energy exchanges using quantum trajectories in ultrastrong coupling
V. Macrì, F. Minganti, A. F. Kockum +3
The dynamics of open quantum systems is often modelled using master equations, which describe the expected outcome of an experiment (i.e., the average over many realizations of the…
Resolution of Gauge Ambiguities in Ultrastrong-Coupling Cavity QED
O. Di Stefano, A. Settineri, V. Macrì +4
Gauge invariance is the cornerstone of modern quantum field theory. Recently, it has been shown that the quantum Rabi model, describing the dipolar coupling between a two-level ato…
Vacuum-Induced Symmetry Breaking in a Superconducting Quantum Circuit
L. Garziano, R. Stassi, A. Ridolfo +2
The ultrastrong-coupling regime, where the atom-cavity coupling rate reaches a considerable fraction of the cavity or atom transition frequencies, has been reported in a flux qubit…
Quantum Electrodynamics of Quantum Dot-Metal Nanoparticles Molecules
A. Ridolfo, O. Di Stefano, N. Fina +2
We study theoretically the quantum optical properties of hybrid molecules composed of an individual quantum dot and a metallic nanoparticle. We calculate the resonance fluorescence…
Emergence of entanglement from a noisy environment: The case of polaritons
S. Portolan, O. Di Stefano, S. Savasta +1
We show theoretically that polariton pairs with a high degree of polarization entanglement can be produced through parametric scattering. We demonstrate that it can emerge in coinc…
