Quantum transport across normal-superlattice-normal graphene junctions: Fabry-Pérot interference, Hofstadter butterfly, and supersnake states
Che-Pin Hsu, Alina Mreńca-Kolasińska, Aitor Garcia-Ruiz +4
Electrostatic modulation of graphene provides a tunable route to engineering miniband structures. We perform quantum transport simulations on a gate-defined graphene superlattice j…
Electronic Reconstruction at the Quasicrystal-Moiré Crossover in Twisted Bilayer Graphene
Kuo-En Chang, Aitor Garcia-Ruiz, Ta-Lei Chou +11
Large twist angles in twisted bilayer graphene are widely expected to be electronically trivial, with negligible interlayer coupling and no electronic reconstruction, in contrast t…
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…
Dimensional and doping stability of Peierls charge density waves in arrays of coupled one-dimensional chains
Aitor Garcia-Ruiz, Che-Pin Hsu, Ming-Hao Liu +1
The Peierls instability, the spontaneous dimerization of a one-dimensional metallic chain at half filling, is a paradigmatic mechanism for charge-density-wave (CDW) formation. Here…
