Coulomb screening of superconductivity in magic-angle twisted bilayer graphene
Julien Barrier, Liangtao Peng, Shuigang Xu +7
The origin of superconductivity in magic-angle twisted bilayer graphene has been a subject of intense debate. While some experimental evidence indicated an unconventional pairing m…
Theory for Lattice Relaxation in Marginal Twist Moirés
Christophe De Beule, Gayani N. Pallewela, Mohammed M. Al Ezzi +3
Atomically thin moiré materials behave like elastic membranes where at very small twist angles, the van der Waals adhesion energy much exceeds the strain energy. In this ``margina…
Scalable tight-binding model for strained graphene
Ming-Hao Liu, Christophe De Beule, Alina MreÅca-KolasiÅska +4
We generalize the scalable tight-binding model for graphene, which allows for efficient quantum transport simulations in the Dirac regime, to account for elastic strain. We show th…
Lattice Relaxation in Moiré Heterobilayers
Christophe De Beule, Yiyang Lai, Liangtao Peng +2
We develop an analytical theory for lattice relaxation in twisted moiré heterobilayers, accounting for lattice mismatch, twist, external biaxial heterostrain, and different elasti…
Gate-Tunable Resonances and 1D Channel in a Graphene Nanoslide
Christophe De Beule, Ming-Hao Liu, Bart Partoens +1
We present a theory of the graphene nanoslide, a fundamental device for graphene straintronics that realizes a single pseudogauge barrier. We solve the scattering problem in closed…
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…
