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.

Mapping the twist-angle disorder and Landau levels in magic-angle graphene [PDF]
Nature, 2020 The recently discovered flat electronic bands and strongly correlated and superconducting phases in magic-angle twisted bilayer graphene (MATBG)1,2 crucially depend on the interlayer twist angle, θ. Although control of the global θ with a precision of about 0.1 degrees has been demonstrated1-7, little information is available on the distribution of the
