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 ...

FOR 2863 - Traceable Terahertz Transceivers (B2)
The B2 project of Meteracom focuses on the signal traceability in electronic THz analog transmit and receive frontends, including their functional building blocks for wideband THz signal generation, translation, amplification and sampling. The main objectives in phase II are to expand the transceiver functionalities towards the traceability of ...

A two-scale model for damage processes during the machining of carbon fiber reinforced plastics
This project includes an experimental characterization of the carbon-fiber-reinforced plastic (CFK) composite and its components, material modeling, CFK machining tests, and simulation-supported analyses of CFK machining. Its main objective is the simulation-supported prediction of machining damage mechanisms of CFK. Four basic relevant damage ...

Du Châtelet's Philosophie und ihre Beziehung zu Leibniz und Wolff: Übereinstimmungen und Unterschiede – Mercator Fellowship
Das hier vorgeschlagene Projekt will die detaillierte Erforschung von Du Châtelets Verhältnis zu Leibniz und Wolff voranzutreiben. Du Châtelets eigene Referenzen auf Leibniz und Wolff beziehen sich hauptsächlich auf ihre metaphysischen Grundlagen und damit auf einen Kern ihres Werkes, vor allem wenn man dieses aus philosophiegeschichtlicher ...

DemoKult – Die unterrichtsbezogene Förderung von Kompetenzen für eine demokratische Kultur
Nicht nur aufgrund des Angriffskriegs Russlands auf die Ukraine steht das demokratische Selbstverständnis in Europa spürbar unter Druck. Auch nationale Ereignisse (z. B. das Erstarken verfassungsfeindlicher Positionen in Parteien des Bundestags und der Landtage; extremistisch motivierte Anschläge in den letzten Jahren) verdeutlichen, dass ein ...

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 ...

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 - Generation and characterization of quantum light in nonlinear systems: A theoretical analysis (C10*)
We develop novel approaches based on integro-differential equations and quantum-channel descriptions for the tailored generation of nonclassical light and its propagation in structured media. By devising a multilinear process matrix formalism and accounting for complex dispersion in photonic crystals, we characterize quantum properties of light. ...

TRR 142 - Polaron signatures in the optical response of lithium niobate (B07*)
This joint theory-experiment project will explore the rich physics of polarons and their optical signatures. In particular, we plan to resolve their influence on the linear and nonlinear optical properties of the material as well as their condensation, hopping and dissociation characteristics in interaction with intrinsic and extrinsic point ...
