Transport effects of twist-angle disorder in mesoscopic twisted bilayer graphene
NanotechnologyAbstract Magic-angle twisted bilayer graphene (TBG) is a tunable material with remarkably flat energy bands near the Fermi level, leading to fascinating transport properties and correlated states at low temperatures. However, grown pristine samples of this material tend to break up into landscapes of twist-angle domains, strongly ...

FUNCTIONAL PROTOTYPE OF PNEUMATIC FLEXIBLE SHAFT COUPLING WITH MECHANICAL CONSTANT TWIST ANGLE REGULATOR [PDF]
Scientific Journal of Silesian University of Technology. Series TransportPneumatic couplings with constant twist angle control are suitable for tuning mechanical systems where the load torque is proportional to the square of shaft speed. This is typical mostly for drives of ships used in water transportation.

Raman imaging of twist angle variations in twisted bilayer graphene at intermediate angles
2D Materials, 2022 Abstract Van der Waals layered materials with well-defined twist angles between the crystal lattices of individual layers have attracted increasing attention due to the emergence of unexpected material properties. As many properties critically depend on the exact twist angle and its spatial homogeneity, there is a

WKB Estimate of Bilayer Graphene’s Magic Twist Angles [PDF]
Physical Review Letters, 2021 Graphene bilayers exhibit zero-energy flat bands at a discrete series of magic twist angles. In the absence of intra-sublattice inter-layer hopping, zero-energy states satisfy a Dirac equation with a non-abelian SU(2) gauge potential that cannot be diagonalized globally.

Magnetoplasmons in magic-angle twisted bilayer graphene
Journal of Physics: Condensed Matter, 2023 Abstract The magic-angle twisted bilayer graphene (MATBLG) has been demonstrated to exhibit exotic physical properties due to the special flat bands. However, exploiting the engineering of such properties by external fields is still in it infancy.
