Thermal effect on magnetoexciton energy spectra in monolayer transition metal dichalcogenides

DN Ly, DN Le, NH Phan, VH Le - Physical Review B, 2023 - APS
It is widely comprehended that temperature may cause phonon-exciton scattering,
enhancing the energy level's linewidth and leading to some spectrum shifts. However, in the …

Polarons and Exciton-Polarons in Two-Dimensional Polar Materials

V Shahnazaryan, A Kudlis, IV Tokatly - arxiv preprint arxiv:2502.03657, 2025 - arxiv.org
We propose a macroscopic theory of optical phonons, Fr {\" oh} lich polarons, and exciton-
polarons in two-dimensional (2D) polar crystalline monolayers. Our theory extends the …
