Orbital occupation selects structural dimensionality in binary transition-metal oxides
Deping Guo, Renhong Wang, Cong Wang +6
Orbital-lattice coupling in transition-metal oxides is usually discussed within a given bonding framework, where orbital occupation is intertwined with local coordination, strain,…
Real-space titration and manipulation of particle-like correlated electrons in doped Mott insulator
Yanyan Geng, Haoyu Dong, Renhong Wang +12
The localized (particle-like) correlated electrons deserve particular attention as they govern various exotic quantum phenomena, such as quantum spin liquids, Wigner crystals, and…
Mechanically and electrically switchable triferroic altermagnet in a pentagonal FeO2 monolayer
Deping Guo, Jiaqi Dai, Renhong Wang +2
Two-dimensional multiferroics promise low-power, multifunctional devices, yet the intrinsic coexistence and mutual control of three coupled ferroic orders in a single layer remains…
Kinetically accessible 1D magnetic chains of transition-metal chalcogenides and halides on van der Waals surfaces
Canbo Zong, Deping Guo, Renhong Wang +9
One-dimensional (1D) chains offer unique opportunities for nanoelectronics and spintronics, yet their experimental realization remains challenging because 1D motifs are often therm…
Filling-dependent intertwined electronic and atomic orders in the flat-band state of 1T-TaS2
Yanyan Geng, Haoyu Dong, Renhong Wang +12
The delicate interplay among the complex intra-/inter-layer electron-electron and electron-lattice interactions is the fundamental prerequisite of these exotic quantum states, such…
