DETECTION OF RELIC NEUTRINOS, SOLAR NEUTRINOS AND WIMPS WITH LEVITATED GRANULES

Detection of the cosmic neutrino background may become possible through coherent interaction with levitated sub-micron granules, utilising refined optical or quantum measurement techniques. Solar neutrinos and WIMPs gain less from coherence but their higher momentum would give measurable recoil velocities in micron size granules. Development of this technique initially as a directional dark matter detector would provide an intermediate step towards future relic neutrino detection.
