Abstract
Using the quantum Monte Carlo method, we investigate the spin dynamics of itinerant electrons in the quarter-filled metallic Hubbard ring, which is aimed at the vanadium ring or chain defined along corner-sharing tetrahedra of LiV2O4. Neutron-scattering cross sections, spin susceptibilities, and spin relaxation rates are evaluated based on the model, from which we find the dramatic changes of magnetic responses and spin fluctuation with the temperature. Such results can explain the central findings in the recent inelastic neutronscattering experiment for LiV2O4.
