Title The physics of exceptional points
Abstract In my talk I will discuss the recent exciting developments associated with non-Hermitian degeneracies, also known as “exceptional points”. After having been studied mostly in the domain of mathematical physics, quite a number of experiments have recently demonstrated how the presence of exceptional points leads to very counter-intuitive effects, such as loss- induced lasing, chiral field modes, topological energy transfer etc. I will try to provide an introduction to this topic as well as an overview of the many different areas of physics in which exceptional points are meanwhile being explored.
