Non-Hermitian Skin Effect from Radiative Coupling in a Reciprocal Chiral Medium
Kin Hung Fung, Changhao Meng, Yixin Xiao +1
We show that long-range radiative coupling in a passive chiral medium produces an unusual non-Hermitian skin effect in a chain of dipoles. The skin-mode profile consists of a long-…
Integer-Graded Reciprocal Skin Effect from Internal Rotation
Kin Hung Fung, C. T. Chan
A prominent class of reciprocal non-Hermitian skin effects has a topological classification, characterized by a parity invariant protected by reciprocity. We show that con…
Scalar-Wave Dispersion in Vectorial Photonic Crystals via Site-Adapted p Orbitals
Yan-Long Chen, Kin Hung Fung, C. T. Chan +1
Electromagnetic waves are intrinsically vectorial and require description via polarization, unlike scalar fields such as acoustic pressure or electronic wavefunctions. In three dim…
Exact flat bands in a 3D photonic crystal
Kin Hung Fung, Yan-Long Chen, C. T. Chan +1
Photonic flat bands are hard to engineer because Maxwell's equations are vectorial: transversality obstructs the localized scalar-like bases that generate destructive-interference…
