Few-mode models — such as the Jaynes-Cummings model and its generalizations — have been an indispensable tool in studying the quantum dynamics of light-matter interactions in optical resonators. Recently, novel regimes featuring strong coupling in combination with large losses have attracted attention in various experimental platforms. In this context, central assumptions of these canonical quantum optical models have to be revisited. In this talk, I will discuss extensions of Jaynes-Cummings-type few-mode models and an associated class of loss-induced multi-mode effects. Besides recent theoretical progress [1-4], I will discuss implications for experiments in x-ray cavity QED with Mössbauer nuclei [5] — an emerging platform at the high-energy frontier of quantum optics, featuring lossy resonators doped with ultra-narrow emitters.
