The Kondo Lattice Model in Infinite Dimensions II. Static Susceptibilities and Phase Diagram
Junya Otsuki, Hiroaki Kusunose, Yoshio Kuramoto
Magnetic and charge susceptibilities in the Kondo lattice are derived by the continuous-time quantum Monte Carlo (CT-QMC) method combined with the dynamical mean-field theory. For…
Evolution of a Large Fermi Surface in the Kondo Lattice
Junya Otsuki, Hiroaki Kusunose, Yoshio Kuramoto
Single-particle spectrum of the Kondo lattice model is derived with use of the continuous-time quantum Monte Carlo method, combined with the dynamical mean-field theory. Crossover…
The Kondo Lattice Model in Infinite Dimensions I. Formalism
Junya Otsuki, Hiroaki Kusunose, Yoshio Kuramoto
A Green-function formalism for the Kondo lattice model is presented, which is designed to be combined with the dynamical mean-field theory. With use of Wick's theorem only for cond…
