  The metal-insulator transition (MIT) in paramagnetic VO2 is studied within
LDA+DMFT(IPT), which merges the local density approximation (LDA) with
dynamical mean field theory (DMFT). With a fixed value of the Coulomb U=5.0eV,
we show how the MIT is understood in a new picture: spectral weight transfer
accompanying the increase in the displacement of V ion ($\perp c$) within the
strong correlation scenario. Within this new scenario, we find good
quantitative agreement with (i) switch of the orbital occupation of
(xy,yz+zx,yz-zx), (ii) thermodynamics, and (iii) the one-electron spectral
function in the metallic phase of VO2. We also compare our results for the
total spectral density with other approaches which use QMC to solve the
impurity problem of DMFT.
