Non-Hermitian physics and phase transitions

A physical system may become non-conservative when it is interacting with its environment. One way to introduce openness is by breaking the Hermiticity, that is, by involving non-Hermitian matrices/operators. This seminar will provide a quick overview of the theoretical background of non-Hermitian physics, followed by a focus on the topic of non-Hermitian phase transitions intertwined with the physics of light-matter interactions.
