Description
Theoretically explaining experimental observations of cavity-modified physics and chemistry remains to be a major challenge, in particular for a large number of coupled molecules. Here I discuss our bottom-up approach with minimal quantum optics many-body models, which include electronic, photonic, and motional degrees of freedom in their simplest form.
This talk will review how dark states acquire a "semilocalized" nature with unusual properties in terms of level statistics and other localization quantifiers. I then discuss how such states can play a crucial role for cavity-modified nuclear dynamics. As a main conclusion, I show that semilocalized states can produce exotic quantum states of motional wave-packets. Surprisingly, those features can remain robust, also in a large-N limit. I then present recent on-going work on how to extend these findings to more realistic models, using new types of advanced numerical approaches.
