The thermodynamic and magnetic properties of a single impurity Anderson model that describes Ce in an environment with hexagonal symmetry is treated within the noncrossing approximation. It is found that the properties of the system at temperatures larger than the crystal field splitting are described by a Kondo temperature of the sixfold-degenerate spin-orbit multiplet and at low temperatures ...

Abstract: We study scattering of a composite quasiparticle, which possesses a degree of freedom corresponding to relative separation between two bound particles, by a delta-like impurity potential on a one-dimensional discrete lattice. Different from a composite object in continuum space, for a composite quasiparticle on a discrete lattice, the entanglement between its relative and centre of ma...

Ionized-impurity scattering is an anisotropic process showing a high preference for small scattering angles. In a Monte Carlo simulation of a semiconductor device many small-angle scattering events have to be processed, although the contribution of these events to carrier momentum relaxation is small. A new method is presented which reduces the amount of smallangle scattering very effectively. ...

The multichannel Kondo model supports effective anyons on the partially screened impurity, as suggested by its fractional impurity entropy. It was recently demonstrated for multi-impurity chiral model, that scattering of an electron through impurities depends anyon's total fusion channel. Here we study correlation between spins. We argue, based a combination conformal field theory, perturbative...

We present density-functional results on the lifetime of the (111) surface state of the noble metals. We consider scattering on the Fermi surface caused by impurity atoms belonging to the 3d and 4sp series. The results are analyzed with respect to film thickness and with respect to separation of scattering into bulk or into surface states. While for impurities in the surface layer the overall t...

We consider non-Fermi liquids in which the inelastic scattering rate has an intrinsic particle-hole asymmetry and obeys $\omega/T$ scaling. show that, contrast to Fermi liquids, this influences low-temperature behaviour of thermopower even presence impurity scattering. Implications for unconventional sign temperature dependence cuprates strange metal (Planckian) regime are emphasized.

Finite-bandwidth effects on the temperature dependence of the mobility of injected carriers in pure organic crystals are explored for a simplifed case of impurity scattering. Temperature-dependent bandwidth effects are discussed briefly through a simplified combination of band and polaronic concepts.

We present the results on the anomalous 2D transport behavior by employing Drude-Boltzmann transport theory and taking into account the realistic charge impurity scattering effects. Our results show quantitative agreement with the existing experimental data in several different systems and address the origin of the strong and non-monotonic temperature dependent resistivity.
