Kondo destruction and valence fluctuations in an Anderson model.
Unconventional quantum criticality in heavy-fermion systems has been extensively analyzed in terms of a critical destruction of the Kondo effect. Motivated by a recent demonstration of quantum criticality in a mixed-valent heavy-fermion system, β-YbAlB(4), we study a particle-hole-asymmetric Anderson impurity model with a pseudogapped density of states. We demonstrate Kondo destruction at a mix...

متن کاملQuantum critical Kondo destruction in the Bose-Fermi Kondo model with a local transverse field
Recent studies of the global phase diagram of quantum-critical heavy-fermion metals prompt consideration of the interplay between the Kondo interactions and quantum fluctuations of the local moments alone. Toward this goal, we study a Bose-Fermi Kondo model (BFKM) with Ising anisotropy in the presence of a local transverse field that generates quantum fluctuations in the local-moment sector. We...
متن کاملCritical charge fluctuations in a pseudogap Anderson model
The Anderson impurity model with a density of states ρ(ε) ∝ |ε|r containing a power-law pseudogap centered on the Fermi energy (ε = 0) features for 0 < r < 1 a Kondo-destruction quantum critical point (QCP) separating Kondo-screened and local-moment phases. The observation of mixed valency in quantum critical β-YbAlB4 has prompted study of this model away from particle-hole symmetry. The critic...
متن کاملConductance fluctuations near Anderson transition
In this paper we report measurements of conductance fluctuations in single crystal samples of Si doped with P and B close to the critical composition of the metal insulator transition (nc ≈ 4 × 10 cm). The measurements show that the noise, which arises from bulk sources, does not diverge as the Ioffe-Regal limit (kF l → 1) is approached from the metallic side. At room temperatures, the magnitud...
