Hole distribution and self-doping enhanced electronic correlation in hole-doped infinite-layer nickelates
Hongbin Qu, Guang-Ming Zhang, Gang Li
The minimal model for infinite-layer nickelates remains under debate, particularly regarding the hybridization between itinerant interstitial- and the correlated Ni-3$d_{x^2-y^2…
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…
Resilient cluster Mott states in layered NbCl against pressure-induced symmetry breaking
Hongbin Qu, Xiaoqun Wang, Hai-Qing Lin +1
In this work, by combining density-functional theory (DFT) with dynamical mean-field calculations (DMFT), we compare the crystal and electronic structures of the prototype cluster…
Direct evidence of intrinsic Mott state and its layer-parity oscillation in a breathing kagome crystal down to monolayer
Huanyu Liu, Wenhui Li, Zishu Zhou +8
We report direct spectroscopic evidence of correlation-driven Mott states in layered NbCl through combining scanning tunneling microscopy (STM) and dynamical mean-field the…
