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…
Tunable Flux Vortices in 2D Dirac Superconductors
Sina Zeytinoğlu, Atac İmamoğlu, Sebastian Huber
The non-trivial geometry encoded in the Quantum Mechanical wavefunctions has important consequences for its single-particle as well as many-body dynamics. Yet, our understanding of…
Interactions and magnetotransport through spin-valley coupled Landau levels in monolayer MoS
Riccardo Pisoni, Andor Kormányos, Matthew Brooks +12
The strong spin-orbit coupling and the broken inversion symmetry in monolayer transition metal dichalcogenides (TMDs) results in spin-valley coupled band structures. Such a band st…
Quantum correlations of confined exciton-polaritons
Aymeric Delteil, Thomas Fink, Anne Schade +3
Cavity-polaritons in semiconductor microstructures have emerged as a promising system for exploring nonequilibrium dynamics of many-body systems. Key advances in this field, includ…
Strong interactions between dipolar polaritons
Emre Togan, Hyang-Tag Lim, Stefan Faelt +2
Nonperturbative coupling between cavity photons and excitons leads to formation of hybrid light-matter excitations termed polaritons. In structures where photon absorption leads to…
