Topological spin-plasma waves
Dmitry K. Efimkin, Mehdi Kargarian
The surface of a topological insulator hosts Dirac electronic states with the spin-momentum locking, which constrains spin orientation perpendicular to electron momentum. As a resu…
Electron-exciton interactions in the exciton-polaron problem
Dmitry K. Efimkin, Emma K. Laird, Jesper Levinsen +2
Recently, it has been demonstrated that the absorption of moderately doped two-dimensional semiconductors can be described in terms of exciton-polarons. In this scenario, attractiv…
Anomalous drag in electron-hole condensates with granulated order
Hong Liu, Allan H. MacDonald, Dmitry K. Efimkin
We explain the strong interlayer drag resistance observed at low temperatures in bilayer electron-hole systems in terms of an interplay between local electron-hole-pair condensatio…
