The influence of substitutional disorder on the transport properties of heavy-fermion systems is investigated. We extend the dynamical mean-field theory treatment of the periodic Anderson model (PAM) to a coherent-potential approximation for disordered strongly correlated electron systems. Considering two distinct local environments of a binary alloy ${A}_{c}{B}_{1\ensuremath{-}c}$ with arbitrary concentration $c$, we explore two types of disorder: on the $f$ site and on the ligand sites. We… 
Non-Fermi-liquid behavior from dynamical effects of impurity scattering in correlated Fermi liquids
The interplay of disorder and interactions is a subject of perennial interest. In this work, we have investigated the effect of disorder due to chemical substitution on the dynamics and transport
Effect of Disorder on Fermi Surface in Heavy Electron Systems
The Kondo lattice model with substitutional disorder is studied with attention to the size of the Fermi surface and the associated Dingle temperature. The model serves for understanding heavy-fermion
Single-site and cellular dynamical mean-field theory of the Anderson-Hubbard model
We study the Anderson-Hubbard model to examine the interplay between the disordered potential and the Hubbard interactions. We use the dynamical mean-field theory (DMFT) with an exact diagonalization
Photo-emission signatures of coherence breakdown in Kondo alloys: dynamical mean-field theory approach
We study the Kondo alloy model on a square lattice using dynamical mean-field theory for Kondo substitution and disorder effects, together with static mean-field approximations. We computed and
Lifshitz transition in Kondo alloys.
This work identifies and characterize two different Fermi-liquid regimes and proposes that both regimes are separated by a Lifshitz transition at x=n(c), which could provide a scenario for the non-Fermi liquid properties that were recently observed in Kondo alloy systems.
Distributed Hybridization Model for Quantum Critical Behavior in Magnetic Quasicrystals
A quantum critical behavior of the magnetic susceptibility was observed in a quasicrystal containing ytterbium. At the same time, a mixed-valence feature of Yb ions was reported, which appears to be

The thermal conductance of the T-shaped double quantum dot strongly coupled to two ferromagnetic leads fulfills a modified Wiedemann-Franz law, also in the regime of suppression of subsequent stages of the Kondo effect by the exchange field resulting from the presence of ferromagnets.
Spin Susceptibility of Magnetic-Ion-Diluted Kondo Insulators
The static spin susceptibility and spectral function of the system corresponding to the magnetic-ion-diluted Kondo insulator is calculated using the framework of dynamical mean-field theory with a
Dilution and non-Fermi-liquid effects in the CePtIn Kondo lattice.
It is shown that the experimental results not only depend on a volume effect as given by the compressible Kondo lattice model of Lavagna but in addition confirm the more complex behaviour recently presented by Burdin and Fulde for a Kondo alloy system in which the magnetic and non-magnetic atoms are distributed randomly.
Fragility of the Kondo insulating gap against disorder: Relevance to recent puzzles in topological Kondo insulators
Kondo insulators are strongly correlated system in which a clean insulating gap emerges only at very low temperature due to many-body effects involving localized $f$-electrons. However, certain Kondo


Disorder-Driven Non-Fermi-Liquid Behavior in Kondo Alloys
We show how a model of disordered Anderson lattices can account for many non-Fermi-liquid features observed in some Kondo alloys. Because of the exponential nature of the Kondo temperature scale
Effects of magnetic-ion dilution in Kondo insulators
On the basis of the periodic Anderson model with randomly distributed impurity sites without f electrons, the effects of magnetic-ion dilution in Kondo insulators are investigated. Using a new scheme

Qualitatively the correct behavior of the electrical resistivity as a function of temperature, Kondo hole concentration, and the filling of the f electrons and the band electrons is obtained.
Anderson-Hubbard model in infinite dimensions.
A detailed, quantitative study of the competition between interaction- and disorder-induced effects in electronic systems is presented, and the Hubbard model with diagonal disorder is investigated analytically and numerically in the limit of infinite spatial dimensions at half-filling.
Dynamics and scaling in the periodic Anderson model
Abstract.The periodic Anderson model (PAM) captures the essential physics of heavy fermion materials. Yet even for the paramagnetic metallic phase, a practicable many-body theory that can
Non-Fermi-liquid behavior in d - and f -electron metals
A relatively new class of materials has been found in which the basic assumption of Landau Fermi-liquid theory—that at low energies the electrons in a metal should behave essentially as a collection
Dynamical mean-field theory of strongly correlated fermion systems and the limit of infinite dimensions
We review the dynamical mean-field theory of strongly correlated electron systems which is based on a mapping of lattice models onto quantum impurity models subject to a self-consistency condition.

A one-dimensional model of the Kondo lattice for $\ensuremath{\nu}$ degenerate conduction electrons interacting with local moments arranged regularly is formulated. The model is integrable and
