Quantum Floquet engineering with an exactly solvable tight-binding chain in a cavity

Abstract

For solid-state experiments, exactly solvable quantum light matter models, where the quantum nature of light is relevant, are scarce. Here, the authors introduce an exactly solvable model, where a one-dimensional tight-binding chain is coupled to a single cavity mode and derive analytic expressions for the ground state, where the photons are squeezed due to the light-matter coupling.
