Theory of x-ray scattering from optically pumped excitons in atomically thin semiconductors
Joris Sturm, Andrei Benediktovitch, Nina Rohringer +1
We propose a framework to explore the internal charge distribution of mesoscopic quasiparticles by inelastic x-ray scattering, while also accounting for the conventional scattering…
Many-Body Rashba Spin-Orbit Interaction and Exciton Spin Relaxation in Atomically Thin Semiconductor Structures
Henry Mittenzwey, Andreas Knorr
We propose a pair spin-orbit interaction (PSOI) mechanism by establishing a mesoscopic many-particle Rashba Hamiltonian. In lowest order, this Hamiltonian self-consistently describ…
Excitonic Theory of the Ultrafast Optical Response of 2D-Quantum-Confined Semiconductors at Elevated Densities
Henry Mittenzwey, Oliver Voigt, Andreas Knorr
An excitonic approach to the ultrafast optical response of confined semiconductors at elevated densities below the Mott transition is presented. The theory is valid from the cohere…
Coulomb Interaction in Atomically Thin Semiconductors and Density-Independent Exciton-Scattering Processes
Henry Mittenzwey, Andreas Knorr, Thorsten Deilmann
In quantum-kinetic approaches to the dynamics of Coulomb-bound many-body correlations such as excitons, trions, biexcitons or higher-order correlations, a detailed knowledge of the…
Theory of In-Plane-Magnetic-Field-Dependent Excitonic Spectra in Atomically Thin Semiconductors
Michiel Snoeken, Paul Steeger, Robert Schmidt +4
The linear absorption spectrum of excitons in TMDC monolayers under the influence of an in-plane magnetic field is theoretically studied. We demonstrate that in-plane magnetic fiel…
Dissecting intervalley coupling mechanisms in monolayer transition metal dichalcogenides
Oleg Dogadov, Henry Mittenzwey, Micol Bertolotti +8
Monolayer (1L) transition metal dichalcogenides (TMDs) provide a unique opportunity to control the valley degree of freedom of optically excited charge carriers due to the spin-val…
