Seminar Report

We are happy to invite Prof. Han Budich from the Dresden University of Technology to give a talk on March 3rd. The topic is Exceptional Topology of Non-Hermitian Systems: from Theoretical Foundations to Novel Quantum Sensors. Prof. Budich started with the review of the topological phases. After the introduction, he introduced the emergence of the exceptional points from non-Hermitian systems. The exceptional points, which are similar to Weyl nodes, possess intrinsic topological properties. Later, he proposed a novel idea of the quantum sensor to probe topological features from non-Hermitian platforms. It is great to have this nice talk.
