Kondo hole in one-dimensional Kondo insulators
arXiv:cond-mat/0406595 · doi:10.1103/PhysRevB.65.174421
Abstract
Properties of a nonmagnetic impurity in Kondo insulators are investigated by considering a one-dimensional Kondo lattice model with depletion of a localized spin. The ground-state phase diagram determined by the Lanczos method shows that the magnetic moment is more stable than in ordinary metals. Temperature dependence of impurity susceptibilities is also studied by using the finite-temperature density-matrix renormalization group.
