A Simple Solvable Model for Heavy Fermion Superconductivity from the Two-Fluid Normal State
Jiangfan Wang, Yu Li, Yi-feng Yang
We propose an exactly solvable momentum-space Kondo-BCS model to study heavy fermion superconductivity. The Kondo interaction is local in momentum space, which can be derived from…
Pair density wave, unconventional superconductivity, and non-Fermi liquid quantum critical phase in frustrated Kondo lattice
Jialin Chen, Jiangfan Wang, Yi-feng Yang
Motivated by the recent discovery of an intermediate quantum critical phase between the antiferromagnetic order and the Fermi liquid in the frustrated Kondo lattice CePdAl, we stud…
Pseudogap Behavior in the Local Spinon Spectrum of Power-Law Diverging Multichannel Kondo Model
Zuodong Yu, Danqing Hu, Jiangfan Wang +1
Motivated by the emergence of higher-order van Hove singularities (VHS) with power-law divergent density of states (DOS) (, ) in materials, we investigat…
Auxiliary-Bath Numerical Renormalization Group Method and Successive Collective Screening in Multi-Impurity Kondo Systems
Danqing Hu, Jiangfan Wang, Yi-feng Yang
We propose an auxiliary-bath algorithm for the numerical renormalization group (NRG) method to solve multi-impurity models with shared electron baths. The method allows us to disen…
Slave fermion interpretation of the pseudogap in doped Mott insulators
Zhuoqing Long, Jiangfan Wang, Yi-feng Yang
We apply the recently developed slave fermion approach to study the doped Mott insulator in the one-band Hubbard and Hubbard-Heisenberg models. Our results produce several subtle f…
Nonlocal Kondo effect and two-fluid picture revealed in an exactly solvable model
Jiangfan Wang, Yi-feng Yang
Understanding the nature of local-itinerant transition of strongly correlated electrons is one of the central problems in condensed matter physics. Heavy fermion systems describe t…
