Fermi polaron-polaritons in charge-tunable atomically thin semiconductors
Cavity spectroscopy measurements elucidate the Fermi polaron nature of the optical excitations in monolayer transition metal dichalcogenides. The dynamics of a mobile quantum impurity in a degenerate
Giant Paramagnetism-Induced Valley Polarization of Electrons in Charge-Tunable Monolayer MoSe_{2}.
It is shown that a magnetic field of 7 T leads to a near-complete valley polarization of electrons in a MoSe_{2} monolayer with a density 1.6×10^{12}  cm^{-2], which paves the way for valleytronics applications.
Interacting Polaron-Polaritons
Photons in certain materials can form massive, strongly interacting quasiparticles, giving rise to nonlinear effects that could be useful in quantum optics.
Optical Amplification by Stimulated Cooling of Polaron-Polaritons
Two dimensional semiconductors provide an ideal platform for exploration of linear exciton and polariton physics, primarily due to large exciton binding and strong light-matter coupling. These
Cavity-coupled double-quantum dot at finite bias: Analogy with lasers and beyond
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 coupled to a
Transport of Neutral Optical Excitations Using Electric Fields
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 drag force of similar
Polaron Polaritons in the Integer and Fractional Quantum Hall Regimes.
This work performs cavity spectroscopy of a two-dimensional electron system in the strong coupling regime, where polariton resonances carry signatures of strongly correlated quantum Hall phases and demonstrates the modification of polaron dressing that is associated with filling factor dependent electron-exciton interactions.
Interaction-Induced Shubnikov-de Haas Oscillations in Optical Conductivity of Monolayer MoSe_{2}.
We report polarization-resolved resonant reflection spectroscopy of a charge-tunable atomically thin valley semiconductor hosting tightly bound excitons coupled to a dilute system of fully spin- and
Exciton–polarons in two-dimensional semiconductors and the Tavis–Cummings model
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 of an exciton and
Probing bath-induced entanglement in a qubit pair by measuring photon correlations
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 properties are
