Description

Motivated by the Hall-effect experiments in YbRh2Si2, we study the ground state and Fermi surface (FS) of a Kondo lattice model in a two-dimensional square lattice with variational Monte Carlo method. We have found the simultaneous occurrence of the antiferromagnetic transition and the FS reconstruction (topological transition) without the breakdown of the Kondo screening. This phase transition is accompanied by the jump of the Hall coefficient and considered to be consistent with the experiment
