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…

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…
