Trion polaron problem in bulk and two-dimensional materials
V. Shahnazaryan, A. Kudlis, K. Varga +2
We develop a microscopic theoryof the trion polaron: a bound state of two electrons and one hole, dressed by longitudinal optical (LO) phonons. Starting from the Frohlich Hamiltoni…

Polarons in two-dimensional polar materials: All-coupling variational theory
A. Kudlis, V. Shahnazaryan, I. V. Tokatly
We present a detailed and self-contained theoretical study of polarons in two-dimensional (2D) polar materials, which extends the classical macroscopic theory of Fröhlich polarons…

Polarons and Exciton-Polarons in Two-Dimensional Polar Materials
V. Shahnazaryan, A. Kudlis, I. V. Tokatly
We propose a macroscopic theory of optical phonons, Fr{ö}hlich polarons, and exciton-polarons in two-dimensional (2D) polar crystalline monolayers. Our theory extends the classica…
