Crossover from exciton polarons to trions in doped two-dimensional semiconductors at finite temperature
A. Tiene, B. C. Mulkerin, J. Levinsen +2
We study systematically the role of temperature in the optical response of doped two-dimensional semiconductors. By making use of a finite-temperature Fermi-polaron theory, we reve…

Exact Quantum Virial Expansion for the Optical Response of Doped Two-Dimensional Semiconductors
B. C. Mulkerin, A. Tiene, F. M. Marchetti +2
We present a quantum virial expansion for the optical response of a doped two-dimensional semiconductor. As we show, this constitutes a perturbatively exact theory in the high-temp…
