Graphene electrodynamics in the presence of the extrinsic spin Hall effect
We extend the electrodynamics of two-dimensional electron gases to account for the extrinsic spin Hall effect (SHE). The theory is applied to doped graphene decorated with a random distribution of absorbates that induce ...
Floquet Weyl phases in a three-dimensional network model
We study the topological properties of three-dimensional (3D) Floquet band structures, which are defined using unitary evolution matrices rather than Hamiltonians. Previously, two-dimensional band structures of this sort ...
Exceptional points and asymmetric mode conversion in quasi-guided dual-mode optical waveguides
Non-Hermitian systems host unconventional physical effects that be used to design new optical devices. We study a non-Hermitian system consisting of 1D planar optical waveguides with suitable amount of simultaneous gain ...
