Phase separation due to quantum mechanical correlations
J. K. Freericks, E. H. Lieb, D. Ueltschi
Abstract
Can phase separation be induced by strong electron correlations? We present a theorem that affirmatively answers this question in the Falicov-Kimball model away from half-filling, for any dimension. In the ground state the itinerant electrons are spatially separated from the classical particles.
