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…
Implementation and topological characterization of Weyl exceptional rings in quantum-mechanical systems
Hao-Long Zhang, Pei-Rong Han, Xue-Jia Yu +8
Non-Hermiticity can lead to the emergence of many intriguing phenomena that are absent in Hermitian systems, enabled by exceptional topological defects, among which Weyl exceptiona…
Quantum phase transition and critical behavior between the gapless topological phases
Hao-Long Zhang, Han-Ze Li, Sheng Yang +1
The phase transition between gapped topological phases represents a class of unconventional criticality beyond the Landau paradigm. However, recent research has shifted attention t…
Non-adiabatic holonomic quantum operations in continuous variable systems
Hao-Long Zhang, Yi-Hao Kang, Fan Wu +2
Quantum operations by utilizing the underlying geometric phases produced in physical systems are favoured due to its potential robustness. When a system in a non-degenerate eigenst…
