Welcome to non-Hermitian topological phenomena

In our Lise Meitner Research Group "Non-Hermitian Topological Phenomena”, we study the topological features on non-Hermitian systems. Non-Hermiticity plays a central role in classical and quantum systems. In the classical realm, this comes about due to, e.g., gain and loss processes in optics, while in the quantum realm, non-Hermiticity describes the dynamics of open quantum systems as well as, e.g., scattering and decay due to, e.g., interactions and disorder. In recent years, non-Hermiticity has been investigated in the context of topology revealing a dramatic enrichment of the phenomenology of topological phases resulting in a new cross-disciplinary research field that is rapidly expanding, as de­­scribed in this review paper­­.

Our independent group was founded as part of the Marquardt Division in November 2021. As of January 2024, Flore Kunst’s group continued as a Lise Meitner Research Group, supported by the Max Planck Society’s Lise Meitner Excellence Program 2.0. Additionally, Flore successfully acquired an ERC Starting Grant.

If you are interested to join for a Bachelor or Master project, please contact Flore Kunst.

Flore will be lecturing about Hermitian and non-Hermitian topology at three schools this year:
Two spring schools in April 2024 - the 18th Capri spring school and YRS2024 Maynooth, as well as at a summer school in June 2024, the QuMat summer school 2024.



This research is funded by the Lise Meitner Excellence Program 2.0 and the European Union.
