The field recently coined as non-Hermitian physics explores the physics of systems described by non-Hermitian operators. It primarily concerns the effects brought about by gain and loss, which arise as systems are coupled to external reservoirs. This seminar series covers the most recent and exciting developments in the field of non-Hermitian physics, ranging from classical physics to open quantum systems. It has a strong interdisciplinary focus, addressing both theory and experiments, and aims to provide an interacting space for different communities to share ideas.
