Kondo destruction quantum critical point: fixed point annihilation and thermodynamic stability
Yiming Wang, Lei Chen, Haoyu Hu +4
A wide range of strongly correlated electron systems exhibit strange metallicity, and they are increasingly recognized as in proximity to correlation-driven localization-delocaliza…
Unconventional Superconductivity from Fermi Surface Fluctuations in Strongly Correlated Metals
Haoyu Hu, Ang Cai, Lei Chen +4
In quantum materials, electrons that have strong correlations tend to localize, leading to quantum spins as the building blocks for low-energy physics. When strongly correlated ele…
Spin-singlet and spin-triplet pairing correlations in antiferromagnetically coupled Kondo systems
Haoyu Hu, Ang Cai, Lei Chen +1
Recent experiments in quantum critical heavy fermion metals have pushed to the fore the question about whether antiferromagnetic fluctuations can promote both spin-singlet and spin…
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…
