Non-Fermi-liquid theory of a compactified Anderson single-impurity model.
We consider a version of the symmetric Anderson impurity model (compactified) which has a non-Fermi liquid weak coupling regime. We find that in the Majorana fermion representation the perturbation theory can be conveniently developed in terms of Pfaffian determinants and we use this formalism to calculate the impurity free energy, self energies, and vertex functions. We also derive expressions...
متن کاملDiagrammatic Theory of Anderson Impurity Models Fermi and Non-fermi Liquid Behavior
We review a recently developed method, based on a pseudoparticle representation of correlated electrons, to describe both Fermi liquid and non-Fermi liquid behavior in quantum impurity systems. The role of the projection onto the physical Hilbert space and the impossibility of slave boson condensation are discussed. By summing the leading coherent spin and charge fluctuation processes in a full...
متن کاملNon-Fermi-liquid behavior in an extended Anderson model.
An extended Anderson model, including screening channels (nonhybridizing, but interacting with the local orbit), is studied within the Anderson-Yuval approach, originally devised for the single-channel Kondo problem. By comparing the perturbation expansions of this model and a generalized resonant level model, the spin-spin correlation functions are calculated which show non-Fermi liquid expone...

متن کاملFermi and Non–fermi Liquid Behavior in Quantum Impurity Systems: Conserving Slave Boson Theory
The question of Fermi liquid vs. non–Fermi liquid behavior induced by strong correlations is one of the prominent problems in metallic local moment systems. As standard models for such systems, the SU(N)×SU(M) Anderson impurity models exhibit both Fermi liquid and non–Fermi liquid behavior, depending on their symmetry. Taking the Anderson model as an example, these lectures first give an introd...
