Abstract

We study the ground state properties of a periodic Anderson model in a two-dimensional square lattice with a variational Monte Carlo method. It is shown that there are two different types of quantum phase transition: a conventional antiferromagnetic transition and a Fermi-surface reconstruction that accompanies a change in the topology of the Fermi surface. The former is induced by the simple back-folding of the Fermi surface, while the latter is induced by the localization of f electrons. The mechanism of these transitions and its relationship with the results of recent experiments on the Fermi surface are discussed in detail.
