TRR 142 - Cavity-enhanced spontaneous parametric down-conversion with temporal filtering using integrated superconducting detectors (C07*)
In this project, we will study the parametric down-conversion in a cavity with integrated superconducting detectors under cryogenic conditions. By using ultrafast driving electronics, we will implement pump filtering in the time domain, by enabling the integrated detector only after the pump has decayed away. The herald photon remains resonant with ...

TRR 142 - Quasi-bound states in the continuum for efficient second harmonic generation and spatial phase tailoring in GaAs metasurfaces (B09*)
In this project, we aim at exploiting highly efficient quasi-bound states in the continuum for optical modes in GaAs nanoresonators. The strong field confinement of these modes will be utilized to tailor the phase and emission patterns of light generated by nonlinear optical processes and to increase the efficiency of light-matter interaction in ...

TRR 142 - Subcycle nonlinearities of ultrastrong light-matter coupling (B08*)
In this project we will investigate subcycle nonlinearities of highly narrowband THz cavity polaritons in the deep-strong light-matter coupling regime. Cyclotron and intersubband resonances of n-type modulation-doped GaAs/AlxGa1-xAs multi quantum wells fabricated by molecular beam epitaxy will be coupled to a novel generation of THz metal ...

Messplatz zur neurowissenschaftlichen Trainingsanalyse
Zur Kraft und Koordination der menschlichen Bewegung und deren Training zur Wiederherstellung von Gesundheit (nach z.B. Sportverletzungen) und der Entwicklung von (sportlicher) Leistung gibt es erstaunlich wenig Evidenz aus einer neurophysiologischen Perspektive. Der Messplatz zur neurowissenschaftlichen Trainingsanalyse soll helfen, durch ...

Factors of Regular Graphs
The main research objective of the present project has been the study of the existence of pairwise disjoint perfect matchings in regular graphs. We prove the existence of highly edge-connected regular graphs which have only „few'' pairwise disjoint perfect matchings.

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 ...

FOR 2863 - Scalable THz Transceiver Impairment Model
Compared to radios operating at purely optical wavelengths or RF/microwave frequencies, the combination of extremely high absolute bandwidths and high relative bandwidths in the THz frequency regime, paired with the severe performance limitations of technologies operating in the so-called "THz-gap", imposes unique challenges on modern digital ...
