Resistivity of the Two-Channel Kondo Model in Infinite Dimensions | | D.L. Cox
; | | Date: |
18 May 1994 | | Subject: | cond-mat | | Affiliation: | Ohio State | | Abstract: | 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 the absence of symmetry breaking phase transitions or applied fields there is a residual resistivity at zero temperature due to the spin disorder scattering off of the two-channel screening clouds. This may explain the unusual resistivity of UBe$_{13}$. For the same limit the single channel Kondo lattice is an insulator states at particle hole symmetry and half filling, but metallic away from particle-hole symmetry or in applied magnetic field. | | Source: | arXiv, cond-mat/9405049 | | Services: | Forum | Review | PDF | Favorites | |
