An Extended Anderson Model that shows Decreasing Resistivity with Decreasing Temperature
S. Suzuki, O. Sakai, Y. Shimizu
Abstract
The resistivity for an extended two channel Anderson model is calculated. When the temperature decreases, it decreases logarithmically, and has T1/2 anomaly at very low temperatures, as seen in some dilute U alloys. The single-particle and the spin excitation spectra are also calculated.
