Room-temperature tuning and probing of Fermi polarons in atomically thin semiconductors on a plasmonic metasurface
Tingting Wu, Francesca Maria Marchetti, Antonio Tiene +9
The Fermi polaron, arising from interactions between a mobile impurity and a degenerate Fermi sea, is a many-body quasiparticle that provides a sensitive probe of strongly correlat…
Efficient calculation of trion energies in monolayer transition metal dichalcogenides
Sangeet S. Kumar, Brendan C. Mulkerin, Antonio Tiene +3
The reduced dielectric screening in atomically thin semiconductors leads to remarkably strong electron interactions. As a result, bound electron-hole pairs (excitons) and charged e…
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…
Effect of fermion indistinguishability on optical absorption of doped two-dimensional semiconductors
A. Tiene, J. Levinsen, J. Keeling +2
We study the optical absorption spectrum of a doped two-dimensional semiconductor in the spin-valley polarized limit. In this configuration, the carriers in the Fermi sea are indis…
Extremely imbalanced two-dimensional electron-hole-photon systems
A. Tiene, J. Levinsen, M. M. Parish +3
We investigate the phases of two-dimensional electron-hole systems strongly coupled to a microcavity photon field in the limit of extreme charge imbalance. Using variational wave f…
