Efficient quadrature-squeezing from biexcitonic parametric gain in atomically thin semiconductors
Emil V. Denning, Andreas Knorr, Florian Katsch +1
Modification of electromagnetic quantum fluctuations in the form of quadrature-squeezing is a central quantum resource, which can be generated from nonlinear optical processes. Suc…
Excitonic theory of doping-dependent optical response in atomically thin semiconductors
Florian Katsch, Andreas Knorr
The interaction of optically excited excitons in atomically thin semiconductors with residual doping densities leads to many-body effects which are continuously tunable by external…
Doping-induced non-Markovian interference causes excitonic linewidth broadening in monolayer WSe
Florian Katsch, Andreas Knorr
Strong Coulomb interactions in atomically thin semiconductors like monolayer WSe induce not only tightly bound excitons, but also make their optical properties very sensible to…
Interlayer exciton valley polarization dynamics in large magnetic fields
Johannes Holler, Malte Selig, Michael Kempf +11
In van der Waals heterostructures (HS) consisting of stacked MoSe and WSe monolayers, optically bright interlayer excitons (ILE) can be observed when the constituent layers…
Theory of the Coherent Response of Magneto-Excitons and Magneto-Biexcitons in Monolayer Transition Metal Dichalcogenides
Florian Katsch, Dominik Christiansen, Robert Schmidt +4
The recent accessibility of high quality, charge neutral monolayer transition metal dichalcogenides with narrow exciton linewidths at the homogeneous limit provides an ideal platfo…
Exciton-Scattering-Induced Dephasing in Two-Dimensional Semiconductors
Florian Katsch, Malte Selig, Andreas Knorr
Enhanced Coulomb interactions in monolayer transition metal dichalcogenides cause tightly bound electron-hole pairs (excitons) which dominate their linear and nonlinear optical res…
Dipolar and magnetic properties of strongly absorbing hybrid interlayer excitons in pristine bilayer MoS

Understanding the ultrafast coupling and relaxation mechanisms between valleys in transition metal dichalcogenide semiconductors is of crucial interest for future valleytronic devi…
Phonon-assisted Photoluminescence from Dark Excitons in Monolayers of Transition Metal Dichalcogenides
Samuel Brem, August Ekman, Dominik Christiansen +7
The photoluminescence (PL) spectrum of transition metal dichalcogenides (TMDs) shows a multitude of emission peaks below the bright exciton line and not all of them have been expla…
Unraveling coherent quantum feedback for Pyragas control
Julia Kabuss, Florian Katsch, Andreas Knorr +1
We present a Heisenberg operator based formulation of coherent quantum feedback and Pyragas control. This model is easy to implement and allows for an efficient and fast calculatio…
