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 elastic…
Scalable tight-binding model for strained graphene
Ming-Hao Liu, Christophe De Beule, Alina Mreńca-Kolasińska +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…
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…
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 ``marginal…
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…
Floquet-Bloch Theory for Nonperturbative Response to a Static Drive
Christophe De Beule, Steven Gassner, Spenser Talkington +1
We develop the Floquet-Bloch theory of noninteracting fermions on a periodic lattice in the presence of a constant electric field. As long as the field lies along a reciprocal latt…
