Twist-induced Out-of-plane Ferroelectricity in Bilayer Hafnia
Jian Huang, Gwan Yeong Jung, Pravan Omprakash +6
Ferroelectric HfO2 is a promising candidate for next-generation memory devices due to its CMOS compatibility and ability to retain polarization at nanometer scales. However, the po…
Itinerant Magnetism in Twisted Bilayer WSe and MoTe
Liangtao Peng, Christophe De Beule, Yiyang Lai +4
Using a self-consistent Hartree-Fock theory, we show that the recently observed ferromagnetism in twisted bilayer WSe [Nat. Commun. 16, 1959 (2025)] can be understood as a Ston…
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…
Quasiparticle energies and excitonic effects of α-RuCl3
Du Li, Li Yang
α-phase Ruthenium (III) chloride (α-RuCl3) has attracted significant attention because of its potential for realizing Kitaev quantum spin liquid. In this work, we employ first-pr…
UOTe: Kondo-interacting topological antiferromagnet in a van der Waals lattice
Christopher Broyles, Sougata Mardanya, Mengke Liu +23
Since the initial discovery of two-dimensional van der Waals (vdW) materials, significant effort has been made to incorporate the three properties of magnetism, band structure topo…
