Role of electron-electron interactions in -valley twisted transition metal dichalcogenides
Christophe De Beule, Liangtao Peng, E. J. Mele +1
We investigate the role of long-range Coulomb interactions in -valley moirés using the self-consistent Hartree-Fock approximation. This platform was recently proposed [Nature 64…
Pseudomagnetic focusing of valley-polarized beams in strained graphene
Alina Mreńca-Kolasińska, Christophe De Beule, Jia-Tong Shi +4
In addition to spin, the low-energy charge carriers in graphene have two inequivalent valley flavors K and K' related by time-reversal symmetry, which can potentially serve as carr…
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…
