Dissipation in the Broadband and Ultrastrong Coupling Regimes of Cavity Quantum Electrodynamics: An Ab Initio Quantized Quasinormal Mode Approach

Chris Gustin, Juanjuan Ren, Sebastian Franke +1

Phenomenological approaches to photon loss have long been the workhorse of cavity-QED, but prove inadequate in the presence of sufficiently broadband light-matter interactions. We…
