Theory of X-ray absorption spectroscopy: a microscopic Bloch equation approach for two-dimensional solid states
Dominik Christiansen, Malte Selig, Jens Biegert +1
We develop a self-consistent Maxwell-Bloch formalism for the interaction of X-rays with two-dimensional crystalline materials by incorporating the Bloch theorem and Coulomb many-bo…
Phonon-assisted inter-valley scattering determines ultrafast exciton dynamics in MoSe bilayers
Sophia Helmrich, Kevin Sampson, Di Huang +10
While valleys (energy extrema) are present in all band structures of solids, their preeminent role in determining exciton resonances and dynamics in atomically thin transition meta…
Negative-mass exciton polaritons induced by dissipative light-matter coupling in an atomically thin semiconductor
M. Wurdack, T. Yun, M. Katzer +5
Dispersion engineering is a powerful and versatile tool that can vary the speed of light signals and induce negative-mass effects in the dynamics of particles and quasiparticles. H…
Impact of optically pumped non-equilibrium steady states on luminescence emission of atomically-thin semiconductor excitons
Malte Selig, Dominik Christiansen, Manuel Katzer +3
The interplay of the non-equivalent corners in the Brillouin zone of transition metal dichalcogenides have been investigated extensively. While experimental and theoretical works c…
