Valence Fluctuations in the Extended Anderson Lattice Model with Quasiperiodicity

Strongly Correlated Electrons 2016-11-03 v1

Abstract

We study valence fluctuations in the extended Anderson model on two-dimensional Penrose lattice, using the real-space dynamical mean-field theory combined with the continuous-time Monte Carlo method. Calculating ff-electron number, cc-ff spin correlations, and magnetic susceptibility at each site, we find site-dependent formations of the singlet state and valence distribution at low temperatures, which are reflected by the quasiperiodic lattice structure. The bulk magnetic susceptibility is also addressed.
