Research Abstract

We are aiming at realizing a state-of-the-art neutron spectrometer, 4SEASONS, with a 100 times higher performance, by utilizing multi-energy neutrons and high intensity of J-PARC neutron source. We will challenge to elucidate the mechanism of the high-Tc superconductivity on 4SEASONS, which is one of the most difficult subject in the solid state physics since 20 century on the discovery.
