Gauge ambiguities imply Jaynes-Cummings physics remains valid in ultrastrong coupling QED

Modelling of light-matter interaction in the ultrastrong coupling regime is still debated. Here, the authors study the consequences of gauge freedom for a two-level system in a single-mode cavity, showing that the Jaynes-Cummings model can outperform the quantum Rabi model even for ultrastrong coupl...
