Unraveling the Mott-Peierls intrigue in vanadium dioxide
Francesco Grandi, A. Amaricci, Michele Fabrizio
Abstract
The authors show in a minimal model for VO2 that electronic and lattice degrees of freedom produce a rich Born-Oppenheimer free energy landscape, with several local minima in one-to-one correspondence with the monoclinic insulator, rutile metal and monoclinic metal phases observed both at and out-of equilibrium.
