Renormalization-group study of a magnetic impurity in a Luttinger liquid
Avraham Schiller, Kevin Ingersent
A generalized Anderson model for a magnetic impurity in an interacting one-dimensional electron gas is studied via a mapping onto a classical Coulomb gas. For weak potential scatte…
Local-moment formation in gapless Fermi systems
Carlos Gonzalez-Buxton, Kevin Ingersent
Perturbative scaling is applied to the Anderson model for a localized level coupled to a Fermi system in which the density of states varies like near the Fermi energy ($E=0…
Frustration-induced non-Fermi-liquid behavior in a three-impurity Kondo model
Bruce C. Paul, Kevin Ingersent
A Kondo model for three spin-one-half impurities placed at the vertices of an equilateral triangle is studied using the numerical renormalization-group method. The impurity spins c…
Behavior of magnetic impurities in gapless Fermi systems
Kevin Ingersent
In a number of systems, including certain semiconductors and unconventional superconductors, the effective density of states varies near the Fermi energy like . The beha…
