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…
Dimensional and doping stability of Peierls charge density waves in arrays of coupled one-dimensional chains
Aitor Garcia-Ruiz, Che-pin Hsu, Che-Pin Hsu +2
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…
Pseudomagnetotransport in Strained Graphene
Alina MreÅca-KolasiÅska, Christophe De Beule, Jia-Tong Shi +4
In graphene, long-wavelength deformations that result in elastic shear strain couple to the low-energy Dirac electrons as pseudogauge fields. Using a scalable tight-binding model,…
Fractal Quantum Transport on MoS2 Superlattices: a System with Tunable Symmetry
Aitor Garcia-Ruiz, Ming-Hao Liu
Electron doping is an excellent tuning knob to explore different phases of matter in two-dimensional (2D) materials. For example, tuning the Fermi level at a van Hove singularity i…
