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…

Excitonic Bose-polarons in electron-hole bilayers
E. A. Szwed, B. Vermilyea, D. J. Choksy +6
Bose polarons are mobile impurities dressed by density fluctuations of a surrounding degenerate Bose gas. These many-body objects have been realized in ultracold atomic gasses and…
