Non-trivial point-gap topology and non-Hermitian skin effect in photonic crystals
Janet Zhong, Kai Wang, Yubin Park +4
We show that two-dimensional non-Hermitian photonic crystals made of lossy material can exhibit non-trivial point gap topology in terms of topological winding in its complex freque…

Three-dimensional random dielectric colloid metamaterial with giant isotropic optical activity
Viktar Asadchy, Cheng Guo, Ihar Faniayeu +1
Motivated by the theoretical observation that isotropic chirality can exist even in completely random systems, we design a dielectric metamaterial consisting of a random colloid of…

Sub-Wavelength Passive Optical Isolators Using Photonic Structures Based on Weyl Semimetals
Viktar Asadchy, Cheng Guo, Bo Zhao +1
We design sub-wavelength high-performing non-reciprocal optical devices using recently discovered magnetic Weyl semimetals. These passive bulk topological materials exhibit anomalo…
