Outline of Final Research Achievements

The final goal of this research is to measure neutrino’s unknown parameters. To this end, we focus on an atomic relaxation process by emitting a neutrino pair and photon from excited states. We have realized generation of macroscopic coherence between vibrational excited and ground states of para-hydrogen molecules in a counter-propagating excitation configuration, and have succeeded in observing two-photon emission (paired super-radiance emission). We also confirmed the observed signal properties, such as intensity and resonance width are consistent with simulation results. The research has deepened both theoretically and experimentally understandings of macro-coherent amplification principle, which is the key notion of atomic neutrino spectroscopy. We continue research works toward realization of two photon condensate states.
