In our independent research group "Non-Hermitian Topological Phenomena" founded in November 2021, we study topology in structures that dissipate or amplify. This is a new emerging field with a wide range of applications in photonics.
Particularly, we investigate phenomena that deviate and go beyond the physics of non-dissipative topological systems both in the single-particle and many-body context. While our focus is currently on improving the theoretical understanding of these systems, we are also interested in moving towards the development of applications and are open to collaborations both with theorists and experimentalists.
If you wish to learn more about this field, here is a recent review paper.
