TL;DR: In this paper, the authors present a route to spectrum reconstruction at all energies by using graphene which is aligned to two hexagonal boron nitride layers, one can make electrons scatter in the differential moire pattern which results in spectral changes at arbitrarily low energies.

TL;DR: By using graphene which is aligned to two hexagonal boron nitride layers, one can make electrons scatter in the differential moiré pattern which results in spectral changes at arbitrarily low energies, and it is demonstrated that the strength of this potential relies crucially on the atomic reconstruction of graphene within the differentialMoiré super cell.

TL;DR: The energy spectrum of a quantum point contact realized by a suitable gate geometry in bilayer graphene is experimentally determined and a spin g factor g_{s}∼2 is found and the results are quantitatively explained.

TL;DR: Measurements of quantized conductance in electrostatically induced quantum point contacts in bilayer graphene show an intricate pattern of lifted and restored degeneracies with increasing field, forming an interweaving pattern that can be reproduced by numerical calculations.

TL;DR: In this paper, the spectrum of subbands in an electrostatically defined quantum wire in gapped bilayer graphene (BLG) directly manifests the minivalley structure and reflects Berry curvature via the associated magnetic moment of the states in the low-energy bands of this two-dimensional material.
