⚝ Introduction
Neutrinos and dark matter are among a few important science drivers
that push forward our knowledge boundary of the fundamental building
blocks of Nature and their interactions. Benefited with huge fluxes,
produced either naturally or artificially, and massive detectors of
ever-improving sensitivities, their direct detection, and hopefully
new discovery, has been taking an important position in the
"intensity" frontier of our search for new physics.
Unlike the "energy" frontier which relies on powerful colliders, most
intensity frontier experiments are conducted at much lower energies
which can overlap with typical nuclear, atomic, molecular, or
condensed-matter scales. Our collaboration grows out of the common
interest in various many-body problems therein. Through detailed study
of many-body physics, our goal is to better understand the detector
responses so that experimental data can be analyzed reliably, and to
identify from the rich energy spectra of many-body systems useful
detector designs with unique signatures, improved precisions, or
enhanced signals.
