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…
