Rich unconventional Hall effects in a single quasi-kagome Kondo Weyl semimetal candidate CeTiSb
Xiaobo He, Ying Li, Yongheng Ge +13
It is generally believed that electronic correlation, geometric frustration, and topology, \textit{individually}, can facilitate the emergence of various intriguing properties that…
Algebraic-Dynamical Perturbation Theory of Large- Hubbard Models. Single Particle Spectrum of Antiferromagnetic Mott Insulating States
Wenxin Ding, Rong Yu
In this work, we present an analytical framework for studying antiferromagnetic (AFM) Mott insulating states in the Hubbard model. We first derive an analytical solution for the si…
Variational Equations-of-States for Interacting Quantum Hamiltonians
Wenxin Ding
Variational methods are of fundamental importance and widely used in theoretical physics, especially for strongly interacting systems. In this work, we present a set of variational…
Giant Nernst effect in the crossover between Fermi liquid and strange metal
Yusen Yang, Qian Tao, Yuqiang Fang +11
The strange-metal state is a crucial problem in condensed matter physics highlighted by its ubiquity in almost all major correlated systems[1-7]. Its understanding could provide im…
Algebraic-Dynamical Theory for Quantum Spin-1/2: the Two-spin limit and Implications for Lattice Models
Wenxin Ding, Chuanru Dai, Zhengfei Hu
Recently, an {\it algebraic-dynamical theory} (ADT) for strongly interacting many-body quantum Hamiltonians in W. Ding, arXiv: 2202.12082 (2022). By introducing the complete operat…
Dynamical Expansion of the Doped Hubbard Model
Wenxin Ding, Rong Yu
We construct a new slave spin representation for the single band Hubbard model in the large- limit. The mean-field theory in this representation is more amenable to descr…
Local Density of States induced near Impurities in Mott Insulators
Wenxin Ding, Qimiao Si
The local density of states near dopants or impurities has recently been probed by scanning tunneling microscopy in both the parent and very lightly doped compounds of the high-$T_…
A Strange Metal from Gutzwiller correlations in infinite dimensions II: Transverse Transport, Optical Response and Rise of Two Relaxation Rates
Wenxin Ding, Rok Žitko, B Sriram Shastry
Using two approaches to strongly correlated systems, the extremely correlated Fermi liquid theory and the dynamical mean field theory, we compute the transverse transport coefficie…
A Strange Metal from Gutzwiller correlations in infinite dimensions
Wenxin Ding, Rok Žitko, Peizhi Mai +2
Recent progress in extremely correlated Fermi liquid theory (ECFL) and dynamical mean field theory (DMFT) enables us to compute in the limit the resistivity of the $…
Anomalous Hall effect and quantum criticality in geometrically frustrated heavy fermion metals
Wenxin Ding, Sarah Grefe, Silke Paschen +1
Studies on the heavy-fermion pyrochlore iridate (PrIrO) point to the role of time-reversal-symmetry breaking in geometrically frustrated Kondo lattices. With this motiv…
Effective Exchange Interactions for Bad Metals and Implications for Iron-based Superconductors
Wenxin Ding, Rong Yu, Qimiao Si +1
The experimentally observed bad metal behavior in parent iron pnictides and chalcogenides suggests that these systems contain strong electronic correlations and are on the verge of…
