Non Fermi Liquid Dynamics of the Two-Channel Kondo Lattice
M. Jarrell, Hanbin Pang, D. L. Cox +2
The paramagnetic phase of the two-channel Kondo lattice model is examined with a Quantum Monte Carlo simulation in the limit of infinite dimensions. We find non-Fermi-liquid behavi…
Two-Channel Kondo Lattice: An Incoherent Metal
Mark Jarrell, Hanbin Pang, D. L. Cox +1
The two-channel Kondo lattice model is examined with a Quantum Monte Carlo simulation in the limit of infinite dimensions. We find non-fermi-liquid behavior at low temperatures inc…
Resistivity of the Two-Channel Kondo Model in Infinite Dimensions
D. L. Cox
Analytic results for the resistivity of the two-channel Kondo lattice in a particular infinite dimensional limit (Lorentzian density of states) are presented. It is argued that in…
A Simple Model for Coupled Magnetic and Quadrupolar Instabilities in Uranium Heavy-Fermion Materials
V. L. Libero, D. L. Cox
We present a mean-field calculation of the phase diagram of a simple model of localized moments, in the hexagonal uranium heavy-fermion compounds. The model considers a non-Kramers…
Selection Rules for Two Channel Kondo Models of U and Ce ions in Metals
D. L. Cox
Symmetry based selection rules are developed providing minimal criteria for the existence of two-channel Kondo interactions between conduction electrons and the low energy degrees…
The Hubbard Model at Infinite Dimensions: Thermodynamic and Transport Properties
Th. Pruschke, D. L. Cox, M. Jarrell
We present results on thermodynamic quantities, resistivity and optical conductivity for the Hubbard model on a simple hypercubic lattice in infinite dimensions. Our results for th…
