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…

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…

Superconducting fluctuations and charge-4 plaquette state at strong coupling
Qiong Qin, Jian-Jun Dong, Yutao Sheng +2
We apply the static auxiliary field Monte Carlo approach to study phase correlations of the pairing fields in a microscopic model with spin-singlet pairing interaction. We find tha…
