Query: Doped Mott insulator as the origin of heavy Fermion behavior in LiV2O4   We investigate the electronic structure of LiV2O4, for which heavy fermion
behavior has been observed in various experiments, by the combination of the
local density approximation and dynamical mean field theory. To obtain results
at zero temperature, we employ the projective quantum Monte Carlo method as an
impurity solver. Our results show that the strongly correlated a1g band is a
lightly doped Mott insulator which -at low temperatures- shows a sharp (heavy)
quasiparticle peak just above the Fermi level, which is consistent with recent
photoemission experiment by Shimoyamada et al. [Phys. Rev. Lett. 96 026403
(2006)].
