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…

Partial quantum revivals of localized condensates in distorted lattices
Dogyun Ko, Meng Sun, Alexei Andreanov +2
We report on a peculiar propagation of bosons loaded by a short Laguerre-Gaussian pulse in a nearly flat band of a lattice potential. Taking a system of exciton-polaritons in a kag…

Exciton-Polariton Topological Insulator with an Array of Magnetic Dots
Meng Sun, Dogyun Ko, D. Leykam +2
Recently there have been several proposals on exciton-polariton topological insulators, most requiring strong external magnetic fields induced by bulky superconducting coils. We pr…
