Beskrivning av projektet
Modern cutting-edge nuclear many-body methods are being developed to be used to description of various phenomena related to fundamental physics - physics of neutrinos and dark matter. The many-body methods exploit novel energy-density functionals and iterative linear-response methods. The applications comprise calculations of beta-decay rates and beta-electron spectra, double beta decays, astrophysics applications, charge-exchange and double charge-exchange reactions, dark-matter direct detection and nuclear muon capture. These calculations help solve fundamental neutrino properties (like absolute mass and neutrino mass hierarchy), degree of quenching in weak axial current in nuclei (through beta-decay and nuclear muon-capture analyses), the reactor antineutrino anomaly, the contaminant electron spectra in dark-matter and rare-events experiments, explain the results of single and double charge-exchange reactions and the problem of the neutrino floor in Xe-based dark-matter experiments.
