Andersen Group El.-Phon. QMC C60 GW Resistivity saturation


The Pauli susceptibility of the A3C60 compounds has been calculated for a multi-band Hubbard model, using a diffusion lattice Monte Carlo method ( Phys. Rev. B 55 , R10165 (1997). It was found that many-body effects enhance the susceptibility by about a factor of three. This is one of the few examples where many-body effects are unambiguously found, although these systems are expected to be strongly correlated. From the calculated susceptibility enhancement and experimental values, the density of states can be estimated.
