Generalized Spectral Decomposition for Quantum Impurity Problems
Jun-Bin Wang, Dongchen Huang, Yi-feng Yang
Solving quantum impurity problems may advance our understanding of strongly correlated electron physics, but its development in multi-impurity systems has been greatly hindered due…

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…
