Spectral correspondences for negatively curved Riemannian locally symmetric spaces
The central goal of this project is to describe Pollicott-Ruelle resonances of locally symmetric spaces using a - to be established - correspondence between these resonances and quantum resonances.There are close connections between the dynamical properties of a free particle on a negatively curved Riemannian locally symmetric space in the ...

FOR 2863: MEtrology for TERAhertz COMmunication (Meteracom)
For the advance of THz communication systems, the capability to perform precise measurements is crucial. Metrology at THz frequencies is however still in its infancy and as of today it only covers detector calibration for characterization of ultrafast devices and measurement uncertainty analysis of different spectrometer types available at THz ...

Semiconductor quantum wells excited by non-classical states of light: Interplay between photonic quantum correlations and many-body interactions in solid state systems
Compared to atomic systems, the theoretical description of the optical properties of bulk semiconductors and nanostructures is significantly more complex but also much richer and over a wide range designable by the choice of the nanostructure geometry and the material composition, e.g., in quantum wells. Whereas in atoms the electronic states are ...
