  1. 14. Fundamental physics with levitated micromagnets
    Andrea Vinante (Istituto Nazionale di Fisica Nucleare)

    Macroscopic and mesoscopic ferromagnets levitated by Meissner effect in vacuum behave as multimode mechanical systems with ultrahigh quality factor and high sensitivity to external magnetic fields. Furthermore, they can be easily coupled to superconducting quantum devices. This suggests the possibility of using this experimental platform for a variety of measurements in the context of...

  2. 15. Atoms as electron accelerators

    11/02/2025, 15:10

    Resonant positron annihilation on atomic electrons is a powerful technique for searching for light new particles that couple to $e^+e^-$. Precise estimates of production rates require a detailed characterisation of atomic electron momentum distributions. I will present a general method that leverages the Compton profile of the target material to accurately account for electron velocity effects...

  3. 16. Searching for Light Dark Matter with Carbon Nanotubes: the ANDROMeDa Project
    Francesco Pandolfi (INFN Rome)
    11/02/2025, 15:50

    Since the discovery of carbon nanotubes in 1991 there has been widespread excitement for their unique chemical, electrical and mechanical properties. The introduction of carbon nanotubes has led to technological breakthroughs in many fields, including electronics, biotechnologies, and chemical sensors. The aim of ANDROMeDa (Aligned Nanotube Detector for Research On MeV Darkmatter) is to...

  5. 17. DELight: The Direct Search Experiment for Light Dark Matter
    Eleanor Katherine Fascione
    11/02/2025, 17:40

    There is vast parameter space to explore for dark matter masses below a few GeV, and the field of direct dark matter detection is constantly expanding to new frontiers. In particular, low mass dark matter candidates necessitate novel detector designs with lower thresholds and alternative target materials compared to e.g. the xenon-based experiments currently providing the strongest overall...
