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…
