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…
