Contributions to a conference proceedings

The nature of retinal shielding pigment in the larval eyes of the midge Clunio marinus was studied by high resolution scanning X-ray fluorescence (XRF) analysis correlated with light microscopy and scanning coherent X-ray diffractive imaging (Ptychography). Clunio is known as a unique model system to decipher mechanisms underlying the complex moon-related rhythms. [...]

The Gerda experiment, situated at Laboratori Nazionali del Gran Sasso is designed to search for the neutrinoless double $\beta$ decay. Bare high purity Ge-diodes enriched to 86 %in $^{76}Ge$ are directly immersed into liquid Ar. [...]

The abundance of lithium-7 confronts cosmology with a long lasting problem between the predictions of standard Big Bang Nucleosynthesis and the baryonic density determined from the Cosmic Microwave Background observations. We investigated the influence of the existence of a mirror world, focusing on models in which miror neutrons can oscillate into ordinary neutrons. [...]

In this presentation we contemplate the problem of dark energy and advocate for a multi-faceted approach to studying its solution. Indeed it may be that, like the philosophers described above, we too cannot understand the nature of our beast by only touching one side of the problem. [...]

This proceeding is an overview on the development and construction of a dual-phase liquid xenon time projection chamber in Mainz. It will be used for the measurement of thescintillation and ionization yield of electronic and nuclear recoils off xenon nuclei in a scattering experiment across a wide range of energies. [...]

In recent year with the advent of optomechanics, physics has gained a new powerful tool for small displacement and small forces sensing. It is based on two key ingredients, a resonant optical cavity and a micro-fabricated mechanical resonator. [...]
