Optical valleytronics of impurity states in two-dimensional Dirac materials
Dogyun Ko, A. V. Morozov, V. M. Kovalev +1
We analyze the valley selection rules for optical transitions from impurity states to the conduction band in two-dimensional Dirac materials, taking a monolayer of MoS2 as an examp…
Bose-Einstein condensate-mediated superconductivity in graphene
M. Sun, A. V. Parafilo, K. H. A. Villegas +2
We propose a mechanism for robust BCS-like superconductivity in graphene placed in the vicinity of a Bose-Einstein condensate. Electrons in the graphene interact with the excitatio…
Nonequilibrium Theory of Photoinduced Valley Hall Effect
I. Vakulchyk, V. M. Kovalev, I. G. Savenko
A recent scientific debate has arisen: Which processes underlie the actual ground of the valley Hall effect (VHE) in two-dimensional materials? The original VHE emerges in samples…
Coherent photogalvanic effect in fluctuating superconductors
V. M. Kovalev, K. Sonowal, I. G. Savenko
We develop a theory of the coherent photogalvanic effect (CPGE) in low-dimensional superconductors in the fluctuating regime. It manifests itself in the appearance of a stationary…
Theory of BCS-like bogolon-mediated superconductivity in transition metal dichalcogenides
Meng Sun, A. Parafilo, K. H. A. Villegas +2
We report on a novel mechanism of BCS-like superconductivity, mediated by a pair of Bogoliubov quasiparticles (bogolons). It takes place in hybrid systems consisting of a two-dimen…
Coherent topological polariton laser
Tristan H. Harder, Meng Sun, Oleg A. Egorov +9
Topological concepts have been applied to a wide range of fields in order to successfully describe the emergence of robust edge modes that are unaffected by scattering or disorder.…
