Enhanced nonlinear interaction of polaritons via excitonic Rydberg states in monolayer WSe2
Jie Gu, Valentin Walther, Lutz Waldecker +7
Strong optical nonlinearities play a central role in realizing quantum photonic technologies. In solid state systems, exciton-polaritons, which result from the hybridization of mat…
Rigid band shifts in two-dimensional semiconductors through environmental screening
Lutz Waldecker, Archana Raja, Malte Rösner +9
We investigate the effects of environmental dielectric screening on the electronic dispersion and the band gap in the atomically-thin, quasi two-dimensional (2D) semiconductor WS$_…
Intrinsic Lifetime of Higher Excitonic States in Tungsten Diselenide Monolayers
Samuel Brem, Jonas Zipfel, Malte Selig +7
The reduced dielectric screening in atomically thin transition metal dichalcogenides allows to study the hydrogen-like series of higher exciton states in optical spectra even at ro…
Ultrafast heat flow in heterostructures of Au nanoclusters on thin-films: atomic-disorder induced by hot electrons
Thomas Vasileiadis, Lutz Waldecker, Dawn Foster +5
We study the ultrafast structural dynamics, in response to electronic excitations, in heterostructures composed of Au nanoclusters on thin-film substrates with the use of f…
