We explore the physics of topological lattice models immersed in c-QED architectures for arbitrary coupling strength with the photon field. We propose the use of the cavity transmission as a topological marker and study its behaviour. For this, we develop an approach combining the input-output formalism with a Mean-Field plus fluctuations description of the setup. We illustrate our results with the specific case of a fermionic Su-Schrieffer-Heeger (SSH) chain coupled to a single-mode cavity…

Controlling topological phases of matter with quantum light

Controlling the topological properties of quantum matter is a major goal of condensed matter physics. A major effort in this direction has been devoted to using classical light in the form of Floquet



Bandgap-assisted quantum control of topological edge states in a cavity

Quantum matter with exotic topological order has potential applications in quantum computation. However, in present experiments, the manipulations on topological states are still challenging. We here

Topological Phases of Polaritons in a Cavity Waveguide.

This work presents a theory of collective polaritonic excitations in a dimerized chain of oscillating dipoles embedded inside a photonic cavity, and upgrades the system from a typical SSH SU(2) model into a largely unexplored SU(3) model.

Hierarchy of correlations: Application to Green's functions and interacting topological phases

We study the many-body physics of different quantum systems using a hierarchy of correlations, which corresponds to a generalization of the $1/\mathcal{Z}$ hierarchy. The decoupling scheme obtained

Topological quantum matter with cold atoms

This is an introductory review of the physics of topological quantum matter with cold atoms. Topological quantum phases, originally discovered and investigated in condensed matter physics, have

Cavity quantum electrodynamics with mesoscopic topological superconductors

We study one-dimensional $p$-wave superconductors capacitively coupled to a microwave stripline cavity. By probing the light exiting from the cavity, one can reveal the electronic susceptibility of

Input- output theory of cavities in the ultrastrong coupling regime : The case of time-independent cavity parameters

We present a full quantum theory for the dissipative dynamics of an optical cavity in the ultrastrong light-matter coupling regime, in which the vacuum Rabi frequency is a significant fraction of the

Cavity QED with cold trapped ions

We analyze the quantum motion of a cold, trapped two-level ion interacting with a quantized light field in a single-mode cavity. We show that in the nonclassical Lamb-Dicke limit the time evolution

Cavity QED with hybrid nanocircuits: from atomic-like physics to condensed matter phenomena

This work presents the experimental state of the art of mesoscopic QED and its theoretical description, and uses cavity photons to reveal the dynamics of electron tunneling between a nanoconductor and fermionic reservoirs.

On the electron-photon coupling in Mesoscopic Quantum Electrodynamics

Understanding the interaction between cavity photons and electronic nanocircuits is crucial for the development of Mesoscopic Quantum Electrodynamics (QED). One has to combine ingredients from atomic

Quantum simulation of a Fermi–Hubbard model using a semiconductor quantum dot array

It is shown that for gate-defined quantum dots this disorder can be suppressed in a controlled manner and a detailed characterization of the collective Coulomb blockade transition is realized, which is the finite-size analogue of the interaction-driven Mott metal-to-insulator transition.
