Electron-Mediated Phonon Polaritons in Quantum Cavities

Mattia Udina, David Hagenmüller, Indranil Paul

Phonon-photon coupling in quantum materials is commonly treated as an effective direct interaction, neglecting the crucial role played by electrons. Here we develop a gauge-invaria…

Enhanced localization length in a disordered one-dimensional band via cavity coupling to delocalized states

Francesco Mattiotti, Guido Pupillo, Jérôme Dubail +1

We investigate the localization properties of cavity-coupled electronic states in disordered systems, motivated by recent proposals of cavity-mediated hopping in quantum Hall syste…

Deep Strong light-matter Coupling in 3D Kane Fermions

Dmitriy Yavorskiy, David Hagenmuller, Noureddine Charrouj +5

Deep strong light-matter coupling represents an extreme non-perturbative regime of quantum electrodynamics, in which the interaction strength exceeds the bare frequencies of the un…

Floquet Engineering of a Quasiequilibrium Superradiant Phase Transition in Landau Polaritons

Wen-Hua Wu, Fuyang Tay, Mengqian Che +3

Superradiant phase transitions (SRPTs), characterized by photon condensation and macroscopic matter polarization, are forbidden in equilibrium for homogeneous fields by no-go theor…

Spontaneous Raman Scattering under Vibrational Strong Coupling: The Critical Role of Polariton Spatial Mode Coherence

Maxime Dherbécourt, Joël Bellessa, Clémentine Symonds +2

Resonant coupling of a vibration to a cavity mode has been reported to dramatically modify spontaneous Raman scattering, but subsequent studies have produced conflicting results. I…

Multifractality in the interacting disordered Tavis-Cummings model

Francesco Mattiotti, Jérôme Dubail, David Hagenmüller +3

We analyze the spectral and transport properties of the interacting disordered Tavis-Cummings model at half excitation filling. We demonstrate that a Poissonian level statistics co…

Anomalous diffusion in the Long-Range Haken-Strobl-Reineker model

Alberto Giuseppe Catalano, Francesco Mattiotti, Jérôme Dubail +4

We analyze the propagation of excitons in a -dimensional lattice with power-law hopping in the presence of dephasing, described by a generalized Haken-Strobl-Rei…

Large Random Arrowhead Matrices: Multifractality, Semi-Localization, and Protected Transport in Disordered Quantum Spins Coupled to a Cavity

Jérôme Dubail, Thomas Botzung, Johannes Schachenmayer +2

We provide an exact solution of large random arrowhead Hamiltonians with diagonal disorder, a minimal model for inhomogeneously broadened quantum emitters coupled to a cavity mode.…

Dark state semilocalization of quantum emitters in a cavity

Thomas Botzung, David Hagenmüller, Stefan Schütz +3

We study a disordered ensemble of quantum emitters collectively coupled to a lossless cavity mode. The latter is found to modify the localization properties of the "dark" eigenstat…

Adiabatic elimination for ensembles of emitters in cavities with dissipative couplings

David Hagenmüller, Stefan Schütz, Guido Pupillo +1

We consider an ensemble of cavity-coupled two-level emitters interacting via full (coherent and dissipative) dipole-dipole interactions. Using an adiabatic elimination procedure we…

Effects of energy extensivity on the quantum phases of long-range interacting systems

Thomas Botzung, David Hagenmüller, Guido Masella +4

We investigate the ground state properties of one-dimensional hard-core bosons interacting via a variable long-range potential using the density matrix renormalization group. We de…

Ensemble-induced strong light-matter coupling of a single quantum emitter

Stefan Schütz, Johannes Schachenmayer, David Hagenmüller +6

We discuss a technique to strongly couple a single target quantum emitter to a cavity mode, which is enabled by virtual excitations of a nearby mesoscopic ensemble of emitters. A c…

Ultrastrong coupling of the cyclotron transition of a two-dimensional electron gas to a THz metamaterial

Giacomo Scalari, Curdin Maissen, Dana Turcinková +8

Artificial cavity photon resonators with ultrastrong light-matter interactions are attracting interest both in semiconductor and superconducting systems, due to the possibility of…
