Quantum Criticality and Dynamical Kondo Effect in an SU(2) Anderson Lattice Model
H. Hu, A. Cai, Q. Si
Metallic quantum criticality often develops in strongly correlated systems with local effective degrees of freedom. In this work, we consider an Anderson lattice model with SU(2) s…
Dynamical Kondo effect and Kondo destruction in effective models for quantum-critical heavy fermion metals
Ang Cai, Haoyu Hu, Kevin Ingersent +2
Quantum criticality in certain heavy-fermion metals is believed to go beyond the Landau framework of order-parameter fluctuations. In particular, there is considerable evidence for…
Bose-Fermi Anderson Model with SU(2) Symmetry: Continuous-Time Quantum Monte Carlo Study
Ang Cai, Qimiao Si
In quantum critical heavy fermion systems, local moments are coupled to both collective spin fluctuations and conduction electrons. As such, the Bose-Fermi Kondo model, describing…
Dynamical scaling of charge and spin responses at a Kondo destruction quantum critical point
Ang Cai, Zuodong Yu, Haoyu Hu +2
Quantum critical points often arise in metals perched at the border of an antiferromagnetic order. The recent observation of singular and dynamically scaling charge conductivity in…
