Direct Measurement of Topological Properties of an Exceptional Parabola
Weiyuan Tang, Kun Ding, Guancong Ma
Non-Hermitian systems can produce branch singularities known as exceptional points (EPs). Different from singularities in Hermitian systems, the topological properties of an EP can…

Exceptional points make an astroid in non-Hermitian Lieb lattice: evolution and topological protection
Yi-Xin Xiao, Kun Ding, Ruo-Yang Zhang +2
An astroid-shaped loop of exceptional points (EPs), comprising four cusps, is found to spawn from the triple degeneracy point in the Brillouin zone (BZ) of a Lieb lattice with near…

Casimir induced instabilities at metallic surfaces and interfaces
Kun Ding, Daigo Oue, C. T. Chan +1
Surface plasmons subject to a surface distortion split asymmetrically in energy resulting in a net lowering of zero-point energy. This is because surface plasmon eigenvalues are th…
