Self-consistent theory of ferromagnetism on the surface of a topological insulator
D. K. Efimkin, V. Galitski
The Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between magnetic impurities, mediated by Dirac surface states on the surface of a topological insulator, leads to impurities fe…

Drag effect and Cooper electron-hole pair fluctuations in a topological insulator film
D. K. Efimkin, Yu. E. Lozovik
Manifestations of fluctuating Cooper pairs formed by electrons and holes populating opposite surfaces of a topological insulator film in the Coulomb drag effect are considered. Flu…

Spin-plasmons in topological insulator
D. K. Efimkin, Yu. E. Lozovik, A. A. Sokolik
Collective plasmon excitations in a helical electron liquid on the surface of strong three-dimensional topological insulator are considered. The properties and internal structure o…
