Microscopic theory of polariton-polariton interactions
Esben R. Christensen, Arturo Camacho-Guardian, Ovidiu Cotlet +4
We develop a comprehensive theoretical model for the interaction strength between a pair of exciton-polaritons in microcavity devices. Ab initio numerical calculations for dipolar…
Exciton-polarons in two-dimensional semiconductors and the Tavis-Cummings model
Atac Imamoglu, Ovidiu Cotlet, Richard Schmidt
The elementary optical excitations of a two-dimensional electron or hole system have been identified as exciton-Fermi-polarons. Nevertheless, the connection between the bound state…
Optical excitations in compressible and incompressible two-dimensional electron liquids
Tobias Graß, Ovidiu Cotlet, Atac İmamoğlu +1
Optically generated electron-hole pairs can probe strongly correlated electronic matter, or, by forming exciton-polaritons within an optical cavity, give rise to photonic nonlinear…
Interacting Polaron-Polaritons
Li Bing Tan, Ovidiu Cotlet, Andrea Bergschneider +5
Two dimensional semiconductors provide an ideal platform for exploration of linear exciton and polariton physics, primarily due to large exciton binding energy and strong light-mat…
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…
