Absence of lattice coherence effects in Ce0.6La0.4Pb3: A magnetic field study
R. Pietri, C. R. Rotundu, B. Andraka +2
The specific heat of polycrystalline Ce0.6La0.4Pb3 has been measured in magnetic fields ranging from 0 to 14 T. After subtraction of a lattice contribution, the specific heat betwe…
Kondo screening in a magnetically frustrated nanostructure: Exact results on a stable, non-Fermi-liquid phase
Kevin Ingersent, Andreas W. W. Ludwig, Ian Affleck
Triangular symmetry stabilizes a novel non-Fermi-liquid phase in the three-impurity Kondo model with frustrating antiferromagnetic interactions between half-integer impurity spins.…
Quantum critical behavior in the Kondo problem with a pseudogap
Kevin Ingersent, Qimiao Si
The variant of the single-impurity Kondo problem in which the conduction-band density of states has a power-law pseudogap at the Fermi energy is known to exhibit a zero-temperature…
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…
