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…

Probing the collective excitations of excitonic insulators in an optical cavity
Elahe Davari, Mehdi Kargarian
The light--matter interaction in optical cavities offers a promising ground to create hybrid states and manipulate material properties. In this work, we examine the effect of light…

Optical drive of amplitude and phase modes in excitonic insulators
Elahe Davari, S. Samaneh Ataei, Mehdi Kargarian
Motivated by recent interests in exploring excitonic condensate as the ground state of some narrow-bandgap semiconductors such as transition metal dichalcogenides and layered chalc…
