We explore the physics of topological lattice models in c-QED architectures for arbitrary coupling strength, and the possibility of using the cavity transmission as a topological marker. For this, we develop an approach combining the input-output formalism with Mean-Field theory, which includes self-consistency and quantum fluctuations to first order, and allows to go beyond the small-coupling regime. We apply our formalism to the case of a fermionic Su-Schrieffer-Heeger (SSH) chain. Our… Expand

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. Expand

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. Expand
