Observation of Resonance of Kagome Flat Band Doublet
Renjie Zhang, Bei Jiang, Xiangqi Liu +19
The interplay between local and itinerant electrons underpins many correlated and topological quantum states. Kagome lattices provide an ideal platform by hosting both flat (locali…
Emergent dynamical Kondo coherence and competing magnetic order in a correlated kagome flat-band metal CsCr6Sb6
Xiangqi Liu, Xuefeng Zhang, Jiachen Jiao +11
Correlated kagome metals host unique electronic states that enable exotic quantum phenomena. In the recently emerged CsCr6Sb6, these manifest through Kondo behavior from localized…
Emerging kinetic-exchange for the enhanced metallic ferromagnetism in CrGeTe under pressure
Jiaming Liu, Xuefeng Zhang, Hongbin Qu +3
The microscopic origin of ferromagnetism in correlated materials remains heavily debated, particularly for the competing mechanisms governing insulating versus metallic phases. In…
Mott insulating phase and coherent-incoherent crossover across magnetic phase transition in 2D antiferromagnetic CrSBr
Fan Wu, Xuefeng Zhang, Yi Chen +15
In two-dimensional van der Waals magnetic materials, the interplay between magnetism and electron correlation can give rise to new ground states and lead to novel transport and opt…
Ultrafast Dynamics of Bilayer and Trilayer Nickelate Superconductors
Y. D. Li, Y. T. Cao, L. Y. Liu +16
In addition to the pressurized high-temperature superconductivity, bilayer and trilayer nickelate superconductors Lan+1NinO3n+1 (n = 2 and 3) exhibit many intriguing properties at…
Correlated flat bands in the paramagnetic phase of triangular antiferromagnets NaBaX(PO) (X = Mn, Co, Ni)
Cong Hu, Xuefeng Zhang, Yunlong Su +1
Flat band systems in condensed matter physics are intriguing because they can exhibit exotic phases and unconventional properties. In this work, we studied three correlated magneti…

Chenhaoping Wen, Tian Qin, Xuefeng Zhang +6
Here we report a combined study of low-temperature scanning tunneling microscopy (STM) and dynamical mean-field theory (DMFT) on PdCrO, a delafossite metal with an antiferromag…
Doniach phase diagram for Kondo lattice model on the square and triangular lattices
Ruixiang Zhou, Xuefeng Zhang, Gang Li
Geometric frustration adds a new competing energy scale to the antiferromagnetic (AFM) Kondo lattice model (KLM). In this work, we systematically study the doniach phase diagram on…
Interface induced Zeeman-protected superconductivity in ultrathin crystalline lead films
Yi Liu, Ziqiao Wang, Xuefeng Zhang +12
Two dimensional (2D) superconducting systems are of great importance to exploring exotic quantum physics. Recent development of fabrication techniques stimulates the studies of hig…
On the quantum spin Hall gap of monolayer 1T'-WTe2
Feipeng Zheng, Chaoyi Cai, Shaofeng Ge +12
Quantum spin Hall (QSH) materials are two-dimensional systems exhibiting insulating bulk and helical edge states simultaneously. A QSH insulator processes topologically non-trivial…
