Anisotropic nanoscale coherent polariton transport in CrSBr

Paritosh Malik, Dogyun Ko, Vita Solovyeva +11

In a combined experimental and theoretical study, we demonstrate anisotropic polariton transport on the nanoscale in the van der Waals antiferromagnet CrSBr. While effective cavity…

Bogolon-mediated light absorption in atomic condensates of different dimensionality

Dogyun Ko, Meng Sun, Vadim Kovalev +1

In the case of structureless bosons, cooled down to low temperatures, the absorption of electromagnetic waves by their Bose-Einstein condensate is usually forbidden due to the mome…

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…
