Mixed-State Topology in Non-Hermitian Systems
Shou-Bang Yang, Pei-Rong Han, Wen Ning +3
Non-Hermitian (NH) systems, owing to the existence of exceptional point (or ring and surface), exhibit exotic topological features which are inaccessible in Hermitian systems. Whil…
Exploring the topology induced by non-Markovian Liouvillian exceptional points
Hao-Long Zhang, Yan Wang, Wen Ning +6
Non-Hermitian (NH) systems can display exotic topological phenomena without Hermitian counterparts, enabled by exceptional points (EPs). So far, investigations of NH topology have…
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),…
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…
Topological Transitions in a Kerr Nonlinear Oscillator
Juan Lin, Shou-Bang Yang, Fan Wu +1
A Kerr nonlinear oscillator (KNO) supports a pair of steady eigenstates, coherent states with opposite phases, that are good for the encoding of continuous variable qubit basis sta…
Scheme for measuring topological transitions in a continuous variable system
Bi-Yao Wang, Hao-Long Zhang, Shou-Bang Yang +3
We propose a scheme for measuring topological properties in a two-photon-driven Kerr-nonlinear resonator (KNR) subjected to a single-photon modulation. The topological properties a…
