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…
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…
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…
Giant paramagnetism induced valley polarization of electrons in charge-tunable monolayer MoSe2
Patrick Back, Meinrad Sidler, Ovidiu Cotlet +4
For applications exploiting the valley pseudospin degree of freedom in transition metal dichalcogenide monolayers, efficient preparation of electrons or holes in a single valley is…
Polaron-Polaritons in the Integer and Fractional Quantum Hall Regimes
Sylvain Ravets, Patrick Knüppel, Stefan Faelt +3
Elementary quasi-particles in a two dimensional electron system can be described as exciton-polarons since electron-exciton interactions ensures dressing of excitons by Fermi-sea e…
Fermi polaron-polaritons in charge-tunable atomically thin semiconductors
Meinrad Sidler, Patrick Back, Ovidiu Cotlet +5
The dynamics of a mobile quantum impurity in a degenerate Fermi system is a fundamental problem in many-body physics. The interest in this field has been renewed due to recent grou…
Probing bath-induced entanglement in a qubit pair by measuring photon correlations
Ovidiu Cotlet, Brendon W. Lovett
Self-assembled quantum dots are ideal structures in which to test theories of open quantum systems: Confined exciton states can be coherently manipulated and their decoherence prop…
Cavity-coupled double-quantum dot at finite bias: analogy with lasers and beyond
Manas Kulkarni, Ovidiu Cotlet, Hakan E. Türeci
We present a theoretical and experimental study of photonic and electronic transport properties of a voltage biased InAs semiconductor double quantum dot (DQD) that is dipole-coupl…
