Moiré Topology in Twisted Structures with Noncollinear Spin-Orbit Coupling
Xilong Xu, Liangtao Peng, Shaffique Adam +1
Moiré superlattices provide a powerful platform for flat bands and correlated topological phases, yet most established examples rely on valley-contrasting Berry curvature in hexago…
Axial Hall Effect in Altermagnetic Lieb Lattices
Xilong Xu, Haonan Wang, Li Yang
We predict a so-called axial Hall effect, a Berry-curvature-driven anomalous Hall response, in Lieb-lattice altermagnets. By constructing a tight-binding model, we identify the axi…
Valley-Selective Linear Dichroism and Excitonic Effects in Lieb-Lattice Altermagnets
Haonan Wang, Xilong Xu, Du Li +1
Altermagnets have recently been recognized as a distinct class of magnetic materials characterized by alternative spin-split electronic structures without net magnetization. Despit…
Alter-Piezoresponse in Two-Dimensional Lieb-Lattice Altermagnets
Xilong Xu, Li Yang
Altermagnetism, featuring alternating spin structures in reciprocal space, has sparked growing interest. Here, we predict novel real-space alternative piezomagnetic and piezoelectr…
Twisted Type-II Rashba Homobilayer: A Platform for Tunable Topological Flat Bands
Xilong Xu, Haonan Wang, Li Yang
The recent discovery of topological flat bands in twisted transition metal dichalcogenide homobilayers and multilayer graphene has sparked significant research interest. We propose…
Gate-Controllable Quadri-Layertronics in 2D Multiferroic Antiferromagnet

Magnetoelectric coupling in insulating multiferroic materials is invaluable for both fundamental research and multifunctional device applications. However, material realization rem…
Dimensionality crossover to 2D vestigial nematicity from 3D zigzag antiferromagnetism in an XY-type honeycomb van der Waals magnet
Zeliang Sun, Gaihua Ye, Mengqi Huang +12
Fluctuations and disorder effects are substantially enhanced in reduced dimensionalities. While they are mostly considered as the foe for long-range orders, fluctuations and disord…
Layer-Polarized Anomalous Hall Effect in Valleytronic van der Waals Bilayers
Ting Zhang, Xilong Xu, Baibiao Huang +3
Layer-polarized anomalous Hall effect (LP-AHE), derived from the coupling between Berry curvature and layer degree of freedom, is of importance for both fundamental physics and dev…
