Rotons in Optical Excitation Spectra of Monolayer Semiconductors
Ovidiu Cotlet, Dominik S. Wild, Mikhail D. Lukin +1
Optically generated excitons dictate the absorption and emission spectrum of doped semiconductor transition metal dichalcogenide monolayers. We show that upon increasing the electr…
Shubnikov-de Haas oscillations in optical conductivity of monolayer MoSe
T. Smoleński, O. Cotlet, A. Popert +8
We report polarization-resolved resonant reflection spectroscopy of a charge-tunable atomically-thin valley semiconductor hosting tightly bound excitons coupled to a dilute system…
Transport of neutral optical excitations using electric fields
Ovidiu Cotlet, Falko Pientka, Richard Schmidt +3
Mobile quantum impurities interacting with a fermionic bath form quasiparticles known as Fermi polarons. We demonstrate that a force applied to the bath particles can generate a dr…
