Valence Fluctuations in the Extended Anderson Lattice Model with Quasiperiodicity
arXiv:1606.06503 · doi:10.7566/JPSJ.85.114706
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 -electron number, - 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.
