Non-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 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 کاملCrossover from Fermi Liquid to Non-Fermi Liquid Behavior in a Solvable One-Dimensional Model
We consider a quantum many-body problem in one-dimension described by a Jastrow type wavefunction, characterized by an exponent λ and a parameter γ. In the limit γ = 0 the model becomes identical to the well known 1/r2 pair-potential model; γ is shown to be related to the strength of a many body correction to the 1/r2 interaction. Exact results for the one-particle density matrix are obtained f...
متن کاملNon-Fermi-Liquid Behavior in Itinerant Antiferromagnets
016405-1 We consider a two-dimensional itinerant antiferromagnet near a quantum-critical point. We show that, contrary to conventional wisdom, fermionic excitations in the ordered state are not the usual Fermi-liquid quasiparticles. Instead, down to very low frequencies, the fermionic self-energy varies as !2=3. This non-Fermi-liquid behavior originates in the coupling of fermions to the longit...
متن کاملCrossover between Fermi liquid and non-Fermi liquid behavior in the non-centrosymmetric compound Yb2Ni12P7.
A crossover from a non-Fermi liquid to a Fermi liquid phase in Yb2Ni12P7 is observed by analyzing electrical resistivity ρ(T), magnetic susceptibility χ(T), specific heat C(T), and thermoelectric power S(T) measurements. The electronic contribution to specific heat, Ce(T), behaves as Ce(T)/T∼-ln(T) for 5 K<T<15 K, which is consistent with non-Fermi liquid behavior. Below T∼4 K, the upturn in Ce...
