| Summary:
The third “Mineral Detection of Neutrinos and Dark Matter” (MD$nu$DM’25)
meeting was held May 20-23, 2025 in Yokohama, Japan, hosted by the Yokohama
Institute for Earth Sciences, Japan Agency for Marine-Earth Science and
Technology (JAMSTEC). These proceedings compile contributions from the workshop
and update the progress of mineral detector research. MD$nu$DM’25 was the
third such meeting, following the first in October of 2022 held at the IFPU in
Trieste, Italy and the second in January of 2024 hosted by the Center for
Neutrino Physics at Virginia Tech in Arlington, USA. Mineral detectors record
and retain damage induced by nuclear recoils in synthetic or natural mineral
samples. The damage features can then be read out by a variety of nano- and
micro-scale imaging techniques. Applications of mineral detectors on timescales
relevant for laboratory experiments include reactor neutrino monitoring and
dark matter detection, with the potential to measure the directions as well as
the energies of the induced nuclear recoils. For natural mineral detectors
which record nuclear recoils over geological timescales, reading out even small
mineral samples could be sensitive to rare interactions induced by
astrophysical neutrinos, cosmic rays, dark matter and heavy exotic particles. A
series of mineral detectors of different ages could measure the time evolution
of these fluxes, offering a unique window into the history of our solar system
and the Milky Way. Mineral detector research is highly multidisciplinary,
incorporating aspects of high energy physics, condensed matter physics,
materials science, geoscience, and AI/ML for data analysis. Although realizing
the scientific potential of mineral detectors poses many challenges, the
MD$nu$DM community looks forward to the continued development of mineral
detector experiments and the possible discoveries that mineral detectors could
reveal.
