Topological hybridisation of plasmons with ferrimagnetic magnons
Cooper Finnigan, Mehdi Kargarian, Dmitry K. Efimkin
We study the formation of hybrid plasmon-magnon modes in a heterostructure comprising a monolayer semiconductor with strong Rashba spin-orbit coupling -- specifically, Janus transi…

Anomalous skew scattering of plasmons in a Dirac electron fluid
Cooper Finnigan, Dmitry K. Efimkin
The Berry phase-related nontrivial electronic band geometries can significantly influence bulk and edge plasmons resulting in their non-reciprocal propagation and opening new oppor…

Giant resonant skew scattering of plasma waves in a two-dimensional electron gas
Cooper Finnigan, Dmitry K. Efimkin
Electron skew scattering by impurities is one of the major mechanisms behind the anomalous Hall effect in ferromagnetic nanostructures. It is particularly strong at the surface of…
