The disorder-induced metal-insulator transition is investigated in a three-dimensional simple
cubic lattice and compared for the presence and absence of time-reversal and spin …

Motivated by the intrinsic non-Fermi-liquid behavior observed in the heavy-fermion
quasicrystal Au 51 Al 34 Yb 15, we study the low-temperature behavior of dilute magnetic …

In single sheets of graphene, vacancy-induced states have been shown to host an effective
spin-1/2 hole that can be Kondo screened at low temperatures. Here, we show how these …

Generalized multifractality characterizes scaling of eigenstate observables at Anderson-
localization critical points. We explore generalized multifractality in 2D systems, with the …

We investigate the Anderson transition found in the spectrum of the Dirac operator of
quantum chromodynamics at high temperature, studying the properties of the critical quark …

We use multifractal finite-size scaling to perform a high-precision numerical study of the
critical properties of the Anderson localization-delocalization transition in the unitary …

In the previous chapter, we traced the history of dilute magnetic impurities in metals and
quantum dots. The SIAM and Kondo models were presented, originally introduced to …

The interplay between incommensurability and strong correlations is a challenging open
issue. It is explored here via numerical renormalization-group (NRG) study of models of a …

We report a simulation of the metal-insulator transition in a model of a doped semiconductor
that treats disorder and interactions on an equal footing. The model is analyzed using …

We investigate the magnetic susceptibility χ (T) of quantum spin chains of N= 1280 spins
with power-law long-range antiferromagnetic couplings as a function of their spatial decay …
