Low-temperature physics of the two-impurity, two-channel Kondo model
Abstract
Numerical renormalization group calculations have shown that any nonzero RKKY coupling between a pair of spin- 1 2 impurities destroys the zero-temperature critical point responsible for the marginal-Fermi-liquid behavior of the single-impurity, two-channel Kondo model. Here we report recent progress on calculating the low-temperature properties of the two-impurity model. © 1994.
