Microscopic theory of nonlinear phase space filling in polaritonic lattices
Kok Wee Song, Salvatore Chiavazzo, Oleksandr Kyriienko
We develop a full microscopic theory for a nonlinear phase space filling (NPSF) in strongly coupled two-dimensional polaritonic lattices. Ubiquitous in polaritonic experiments, the…
Theory for Coulomb scattering of trions in 2D materials
Kok Wee Song, Salvatore Chiavazzo, Ivan A. Shelykh +1
We develop a theoretical description of Coulomb interactions between trions (charged excitons) that define a nonlinear optical response in doped two-dimensional semiconductors. Fir…
Superexchange and spin-orbit coupling in monolayer and bilayer chromium trihalides
Kok Wee Song, Vladimir I Fal'ko
We build a microscopic model to study the intra- and inter-layer superexchange due to electrons hopping in chromium trihalides (, X= Cl, Br, and I). In evaluating t…
Attractive trion-polariton nonlinearity due to Coulomb scattering
Kok Wee Song, Salvatore Chiavazzo, Ivan A. Shelykh +1
We theoretically investigate the nonlinearity of trion-polaritons in a two-dimensional material that arises from Coulomb interaction between quasiparticles. To evaluate the interac…
