Kondo insulators in the periodic Anderson model: a local moment approach
The symmetric periodic Anderson model is well known to capture the essential physics of Kondo insulator materials. Within the framework of dynamical mean-field theory, we develop a local moment approach to its single-particle dynamics in the paramagnetic phase. The approach is intrinsically nonperturbative, encompasses all energy scales and interaction strengths, and satisfies the low-energy di...
متن کاملA local moment approach to the degenerate Anderson impurity model.
The local moment approach is extended to the orbitally degenerate (SU(2N)) Anderson impurity model (AIM). Single-particle dynamics are obtained over the full range of energy scales, focusing on particle-hole symmetry in the strongly-correlated regime where the onsite Coulomb interaction leads to many-body Kondo physics with entangled spin and orbital degrees of freedom. The approach captures ma...
متن کاملSpin-Dependent Local Moment Approach to Anderson Impurity Model
We present an extension of the local moment approach to the Anderson impurity model with spin-dependent hybridization. By employing the two self-energy description, as originally proposed by Logan and coworkers, we applied the symmetry restoration condition for the case with spin-dependent hybridization. Self-consistent ground states were determined through the variational minimization of groun...
متن کاملSingle-particle dynamics of the Anderson model: a local moment approach
A non-perturbative local moment approach to single-particle dynamics of the general asymmetric Anderson impurity model is developed. The approach encompasses all energy scales and interaction strengths. It captures thereby strong coupling Kondo behaviour, including the resultant universal scaling behaviour of the single-particle spectrum; as well as the mixed valent and essentially perturbative...
متن کاملFerromagnetism and Kondo insulator behavior in the disordered periodic Anderson model.
The effect of binary alloy disorder on the ferromagnetic phases of f-electron materials is studied within the periodic Anderson model. We find that disorder in the conduction band can drastically enhance the Curie temperature T{c} due to an increase of the local f moment. The effect may be explained qualitatively and even quantitatively by a simple theoretical ansatz. The emergence of an alloy ...
