Why Rare & Invisible
Why Rare & Invisible
Some of the most intriguing questions in physics involve phenomena that are rare, elusive, or invisible.
The Rare & Invisible Physics Lab @ Jeju National University explores these phenomena through neutrino and dark matter experiments, rare-event searches, detector development, and muon tomography. We work with international collaborations including COSINE, NEON, AMoRE, and DUNE, while developing new experimental approaches to search for subtle signals beyond the Standard Model.
Our muon tomography R&D extends these techniques beyond fundamental particle physics, using naturally occurring muons to explore Jeju's subsurface structures, including groundwater and natural cavities, with potential applications to volcanic monitoring and environmental studies.

The COSINE-100 experiment is an underground particle physics project searching for dark matter. Located at the Yemi Underground Laboratory in South Korea, it uses ultra-pure sodium iodide crystals to detect Weakly Interacting Massive Particles (WIMPs). Its primary goal is to test the controversial claim of dark matter discovery made by the DAMA/LIBRA experiment.
NEOS
NEOS
NEOS (Neutrino Experiment for Oscillation at Short baseline) is a particle physics experiment conducted at the Hanbit Nuclear Power Plant in South Korea. It utilizes a one-ton liquid scintillator detector to search for sterile neutrinos, a hypothetical new type of particle. By measuring the neutrino flux just 24 meters from the reactor core, NEOS provides high-precision data to test neutrino oscillation models and the "reactor antineutrino anomaly."
NEON (Neutrino Elastic-scattering Observation with NaI) is a particle physics experiment located at the Hanbit Nuclear Power Plant in South Korea. It aims to observe coherent elastic neutrino-nucleus scattering (CEvNS) using high-purity NaI(Tl) crystals. Situated 24 meters from the reactor core, NEON also searches for light dark matter and axion-like particles, providing world-leading constraints in unexplored mass regions.
AMoRE (Advanced Mo-based Rare process Experiment) is an international search for neutrinoless double beta decay using cryogenic detectors. Located at Yemilab, South Korea, it uses 100Mo-enriched crystals at millikelvin temperatures to determine if neutrinos are their own antiparticles and measure their absolute mass.
DUNE (Deep Underground Neutrino Experiment) is a flagship international project aimed at uncovering the mysteries of neutrinos. It involves sending a high-intensity neutrino beam from Fermilab, Illinois, to a massive liquid argon detector 1.5 km underground in South Dakota. By studying neutrino oscillations, DUNE seeks to understand the origin of matter in the universe, search for proton decay, and observe supernova neutrino bursts.
