Weak localization and universal conductance fluctuations in large area twisted bilayer graphene

Spenser Talkington, Debarghya Mallick, An-Hsi Chen +7

We study diffusive magnetotransport in highly p-doped large area twisted bilayer graphene in 1°, 7°, 9° and 20° samples. We report weak localization in twisted bilayer graphene for…

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…

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…

Squeezing Quantum States in Three-Dimensional Twisted Crystals

Vo Tien Phong, Kason Kunkelmann, Christophe De Beule +4

A fundamental idea in wave mechanics is that propagation in a periodic medium can be described by Bloch waves whose conserved crystal momenta define their transformations when disp…

Elastic Screening of Pseudogauge Fields in Graphene

Christophe De Beule, Robin Smeyers, Wilson Nieto Luna +2

Lattice deformations in graphene couple to the low-energy electronic degrees of freedom as effective scalar and gauge fields. Using molecular dynamics simulations, we show that the…
