Relative hybridization textures as local coordinates for band geometry and topology
Caiyuan Ye, Zhong Fang, Hongming Weng +1
Global diagnostics such as Berry curvature and quantum metrics characterize the geometry and topology of an occupied Bloch subspace, leaving the microscopic sectors that carry this…
A Catalogue of Topological Moiré Bands in Twisted Semiconductors
Jiaheng Li, Yan Zhang, Jiaxuan Liu +5
Twisted two-dimensional semiconductors provide a route to flat and topological moiré minibands, but systematic principles for organizing their material dependence have remained unc…
Entropy-Driven Structural Phase Transition in NbCl via Density Functional Theory and an Effective Model
Chenjie Zhu, Shuai Zhang, Zhong Fang +3
As a prototypical flat-band cluster Mott insulator on an effective triangular lattice, NbCl is a potential candidate for hosting a quantum spin liquid (QSL) state. Neverthe…
A Geometric Design Principle for Topological Phases in Twisted Triangular-Lattice Bilayers
Jiaheng Li, Jiaxuan Liu, Yan Zhang +3
Twisted van der Waals bilayers provide a versatile platform for moiré electronic states, yet a transferable symmetry-based principle for time-reversal-invariant moir…
Three-dimensional topological ferroelectrics
Haohao Sheng, Sheng Zhang, Zhong Fang +2
Three-dimensional (3D) topological ferroelectric (FE) insulators, in which topological and FE orders naturally coexist, enable field-controlled spintronic devices. In this work, we…
Disentangling Anomalous Hall Effect Mechanisms and Extra Symmetry Protection in Altermagnetic Systems
Yuansheng Bu, Ziyin Song, Zhong Fang +2
We investigate the evolution of Anomalous Hall Conductivity (AHC) in a coplanar and collinear antiferromagnetic system with varying spin canting angles. A tight-binding model based…
