TL;DR: In this article, the effect of hexagonal boron nitride (hBN) layer closely aligned with twisted bilayer graphene (TBG) was studied. And they found that for a realistic combination of the twist angle in the TBG and the twisted angle between the hBN and the graphene layer, the system can be described using a single moir\'e unit cell.

TL;DR: In this article, the authors show that the nonlinear effects of the Berry dipole can exceed the linear response for moderate applied fields, and the dependence of these effects on applied strain, coupling to the substrate, density of carriers, and temperature, makes them highly tunable.

TL;DR: In this article, the role of long-range electron-electron interactions near the first magic angle was analyzed in the band structure of twisted trilayer graphene, and superconducting phases with either spin-singlet/valley-triplet or spin-triplets/valleyssinglet symmetry were found with critical temperatures up to a few Kelvin.

TL;DR: In this paper, the local density of states and the Landauer-Buttiker transmission through an angle disorder barrier with a width comparable to the moir\'e period were computed using a decimation technique based on real-space description.

TL;DR: In this paper, the effect of Coulomb interaction on twisted bilayer graphene was investigated, treated within the self-consistent Hartree-Fock approximation, and it was shown that the on-site part of the Fock potential strongly modifies the band structure at charge neutrality.
