1 Observing topological effects with infrared light

Colors are determined by the interaction between the light and materials, providing one of the most valuable information to know about the surrounding world. As our eyes can detect the colors reflected by matter, spectroscopy is aimed at determining the nature of materials through their interaction with light, over a broader range than the visible light. Focusing on infrared light, the determination of the vibrational excitations provide information on various properties of matter, including topological effects.

3 NUCLEUS & CEvNS: Measuring reactor neutrinos with cryogenic detectors

Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) is an interaction well predicted by the Standard Model. Its large cross-section allows to study neutrinos with relatively small detectors. Precision measurement of the CEvNS cross-section is a way to study neutrino properties and search for new physics beyond the Standard Model. The NUCLEUS experiment aims to detect and characterize CEvNS using reactor neutrinos, in an ultra-low background environment. The experiment will be installed between two 4.25 GW reactor cores at the Chooz-B nuclear power plant in France. The experiment is currently under commissioning and all the detectors are being characterized. NUCLEUS will provide important insights into neutrino physics and potential new physics beyond the Standard Model. In this talk, an overview of CEvNS and NUCLEUS will be presented as well as the first characterization of the NUCLEUS detectors via calibrated nuclear recoils.
