Welcome to OMNIA (Oscillations, Mass, Neutrinos, Interaction, Astroparticle), a new research group at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg. Our work builds on more than 25 years of experience in neutrino physics and dark matter, through experiments such as EROS-2 (microlensing dark matter search), Double Chooz (neutrino oscillations), Nucifer (reactor monitoring and safeguards), KATRIN (neutrino mass), and NUCLEUS/CRAB (coherent neutrino scattering and low-energy calibration).

We are currently involved in two major international efforts: KATRIN, where we lead analyses on sterile-neutrino and Big-Bang relic-neutrino searches, and CRAB, where we study nuclear recoils from coherent neutrino–nucleus scattering and light dark matter interactions using cryogenic detectors made of CaWO₄, Al₂O₃, and Ge operating at around 10 mK.

Beyond our main experiments, we explore new ideas to detect and study neutrinos and to investigate their properties using alternative methods that take advantage of technologies developed over the past three decades. These efforts often take place at the crossroads of particle, nuclear, atomic, and solid-state physics, where the experimental energy scale matches the physics we aim to probe.
