Non-Hermitian topology in a single driven-dissipative Kerr-Cat qubit

Pei-Rong Han, Huiye Qiu, Hao-Long Zhang +3

The intriguing physical phenomena associated with exceptional points have established non-Hermitian physics as a frontier of modern research. Recent investigations have extended no…

A hypersphere-like non-Abelian Yang monopole and its topological characterization

Shou-Bang Yang, Pei-Rong Han, Wen Ning +3

Synthetic monopoles, which correspond to degeneracies of Hamiltonians, play a central role in understanding exotic topological phenomena. Dissipation-induced non-Herminicity (NH),…

Experimental observation of non-Markovian quantum exceptional points

Hao-Long Zhang, Pei-Rong Han, Fan Wu +3

One of the most remarkable features that distinguish open systems from closed ones is the presence of exceptional points (EPs), where two or more eigenvectors of a non-Hermitian op…

An exceptional surface and its topology

Shou-Bang Yang, Pei-Rong Han, Wen Ning +3

Non-Hermitian (NH) systems can display exceptional topological defects without Hermitian counterparts, exemplified by exceptional rings in NH two-dimensional systems. However, exce…
