By means of the LDA+DMFT method, we investigate
the electronic structure of LiV2O4, for
which various heavy-fermion-like behaviors have
been observed experimentally.
To obtain the spectral function at T->0, we
employ the projective quantum Monte Carlo method
as the solver of the effective impurity problem
in DMFT. We show that a sharp peak appears just
above the Fermi level at T=0, which is consistent
with the recent photoemission experiment by
