FOR 5208 - Modelling and simulation of the coupled acoustic, electrical, and thermal dynamics of piezoceramics
The determination of material parameters of piezoceramics for actuator applications by means of an inverse method requires an efficient method for the simulation of the different physical processes in the piezoceramic sample. In addition to the electrostatic equations and acoustic wave propagation, this project focuses on the causal description of ...

TRR 142 - Three-photon state generation with on-chip pump suppression in topological waveguides (A09*)
In this project, we experimentally and theoretically study a degenerate four-wave mixing source for the generation of three-photon states, where the photons are generated inside the topological mode and propagate away from the interaction region. The design using topological protected surface modes intrinsically provides a strong suppression of the ...

TRR 142 - Nonlinear strong-field dynamics of atomically thin transition metal dichalcogenides (A10)
Monolayers of Transition Metal Dichalcogenides (TMDCs) exhibit very high exciton binding energies of several hundred meV and extraordinarily strong optical nonlinearities. Stacking several monolayers allows one to tailor these properties by the choice of materials and their relative orientation. We will explore and manipulate such samples by using ...
