Exactly solvable models for light-matter interaction

Dr Daniel Braak
Augsburg University

I shall review developments in the theory of elementary models to describe the interaction of light (bosons) with matter (fermions), which have been motivated by the recent dramatic progress towards experimental realization of the so-called deep strong coupling region. Relations with the classical theory of analytic functions and the role of discrete and continuous symmetries are especially emphasized.
