Probing Collective and Individual Kondo Screening: Multi-Stage, Multi-Channel Kondo Effects in a -Symmetric Four-Impurity Model
Danqing Hu, Jiangfan Wang, Zixiang Hu +1
Collective screening has been proposed to underlie the basic physics of multi-impurity and lattice Kondo systems. But how to establish this picture and distinguish it from individu…
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…
Continuous ferromagnetic quantum phase transition on an anisotropic Kondo lattice
Jialin Chen, Jiangfan Wang, Danqing Hu +1
Motivated by the recent discovery of ferromagnetic quantum criticality in the heavy fermion compound CeRhGe, we develop a numerical algorithm of infinite projected entangle…
Learning disentangled representation for classical models
Dongchen Huang, Danqing Hu, Yi-feng Yang
Finding disentangled representation plays a predominant role in the success of modern deep learning applications, but the results lack a straightforward explanation. Here we apply…
Schwinger boson approach for the dynamical mean-field theory of the Kondo lattice
Rulei Han, Danqing Hu, Jiangfan Wang +1
We apply the dynamical large- Schwinger boson technique as an impurity solver for the dynamical mean-field theory (DMFT) calculations of the Kondo lattice model. Our approach ca…
Energy-scale cascade and correspondence between Mott and Kondo lattice physics
Danqing Hu, Ning-Hua Tong, Yi-feng Yang
We propose an energy-scale correspondence between the Mott physics and the Kondo lattice physics and construct a tentative phase diagram of their correlated electrons with two char…
Effective classical correspondence of the Mott transition
Danqing Hu, Jian-Jun Dong, Li Huang +2
We derive an effective classical model to describe the Mott transition of the half-filled one-band Hubbard model in the framework of the dynamical mean-field theory with hybridizat…
Hybridization fluctuations in the half-filled periodic Anderson model
Danqing Hu, Jian-Jun Dong, Yi-feng Yang
Motivated by recent photoemission and pump-probe experiments, we report determinant Quantum Monte Carlo simulations of hybridization fluctuations in the half-filled periodic Anders…
Symmetry-enforced heavy-fermion physics in the quadruple-perovskite CaCu3Ir4O12
Min Liu, Yuanji Xu, Danqing Hu +6
Heavy-fermion materials are mostly rare-earth or actinide intermetallics with very few exceptions in d-electron systems. The physical mechanism for these d-electron heavy fermion s…
Hybridization oscillation in the one-dimensional Kondo-Heisenberg model with Kondo holes
Neng Xie, Danqing Hu, Yi-feng Yang
We use the density matrix renormalization group method to study the properties of the one-dimensional Kondo-Heisenberg model doped with Kondo holes. We find that the perturbation o…
