Over the last few years there has been a new resurrection of non-Hermitian physics across various fields in both classical and quantum physics, ranging from condensed matter, atomic and photonic systems, soft matter and stochastic models to high-energy and quantum field theories. One of the recent major developments in this area revolves around the topological and symmetry protected phase. It has been shown that many notions such the concept of the gap, nature of gapless structures and bulk boundary correspondence vary drastically from the Hermitian topological phases. Despite the developments in all these directions, a unified understanding of the interplay between these emergent notions is lacking. The workshop plans to represent major developments of the field in various platforms.
