Realistic simulation of Kondo lattice model: application to Cerium compounds

ORAL

Abstract

In order to do a good description of heavy fermion materials at very low temperatures, we simulate the Kondo lattice model with the continuous-time quantum Monte Carlo method recently developed by one of the authors [1] combined with the conduction-electron density of states given by first-principle calculations and performing self consistency using dynamical mean field theory. We discuss our results for Cerium compounds down to the temperature range of O(1) [K] using realistic values of crystal-field and spin-orbit level splitting. [1] J. Otsuki, H. Kusunose, P. Werner, Y.
