We study quantum effects of the vacuum light-matter interaction in materials embedded in optical cavities. We focus on the electronic response of a two-dimensional semiconductor placed inside a planar cavity. By using a diagrammatic expansion of the electron-photon interaction, we describe signatures of light-matter hybridization characterized by large asymmetric shifts of the spectral weight at resonant frequencies. We follow the evolution of the light-dressing from the cavity to the free…

Cavity Control of Excitons in Two-Dimensional Materials
TLDR
A robust and efficient way of controlling the optical spectra of two-dimensional materials and van der Waals heterostructures by quantum cavity embedding by solving the coupled electron–photon Schrödinger equation in a quantum-electrodynamical extension of the Bethe-Salpeter approach is proposed.
Strong coupling of ionizing transitions
In cavity quantum electrodynamics, strong light–matter coupling is normally observed between a photon mode and a discrete optically active transition. In the present work we demonstrate that strong
Cavity quantum-electrodynamical polaritonically enhanced electron-phonon coupling and its influence on superconductivity
TLDR
It is found that through highly polarizable dipolar phonons, large cavity-enhanced electron-phonon couplings are possible, but superconductivity is not enhanced for the forward-scattering pairing mechanism due to the interplay between coupling enhancement and mode softening.
Manipulating quantum materials with quantum light
We show that the macroscopic magnetic and electronic properties of strongly correlated electron systems can be manipulated by coupling them to a cavity mode. As a paradigmatic example we consider the
Quantum well infrared photo-detectors operating in the strong light-matter coupling regime
We report quantum well mid-infrared photo-detectors operating in the strong light-matter coupling regime. We claim that this is an ideal system to elucidate the elusive problem in intersubband
Cavity-Enhanced Transport of Charge.
TLDR
This work theoretically investigate charge transport through electronic bands of a mesoscopic one-dimensional system, where interband transitions are coupled to a confined cavity mode, initially prepared close to its vacuum and shows that the charge conductivity enhancement can reach orders of magnitudes under experimentally relevant conditions.
Cavity quantum electrodynamical Chern insulator: Towards light-induced quantized anomalous Hall effect in graphene
We show that an energy gap is induced in graphene by light-matter coupling to a circularly polarized photon mode in a cavity. Using many-body perturbation theory, we compute the electronic spectra
Superradiant Quantum Materials.
TLDR
This work shows that a phase characterized by the simultaneous condensation of excitons and photon superradiance can be realized, hence stabilizing and intertwining two collective phenomena which are rather elusive in the absence of this cooperative effect.
Magneto-transport controlled by Landau polariton states
Hybrid excitations, called polaritons, emerge in systems with strong light–matter coupling. Usually, they dominate the linear and nonlinear optical properties with applications in quantum optics.
Cavity Quantum Eliashberg Enhancement of Superconductivity.
TLDR
Coupling a two-dimensional superconducting film to the quantized electromagnetic modes of a microwave resonator cavity is theoretically considered and it is predicted that by tailoring the cavity environment, enhancement can be observed in a variety of parameter regimes, offering a large degree of tunability.
