First-order photon condensation in magnetic cavities: A two-leg ladder model

Z Bacciconi, GM Andolina, T Chanda, G Chiriacò… - SciPost Physics, 2023 - scipost.org
We consider a model of free fermions in a ladder geometry coupled to a non-uniform cavity
mode via Peierls substitution. Since the cavity mode generates a magnetic field, no-go …
