We propose magic-angle helical trilayer graphene (HTG), a helical structure featuring
identical rotation angles between three consecutive layers of graphene, as a unique and …

The electronic properties of van der Waals (vdW) structures can be substantially modified by
the moiré superlattice potential, which strongly depends on the twist angle among the …

This is an update of a previous review (Naumis et al 2017 Rep. Prog. Phys. 80 096501).
Experimental and theoretical advances for straining graphene and other metallic, insulating …

We study the effects of strain in moiré systems composed of honeycomb lattices. We
elucidate the formation of almost perfect one-dimensional moiré patterns in twisted bilayer …

In 'magic angle'twisted bilayer graphene (TBG) a flat band forms, yielding correlated
insulator behavior and superconductivity. In general, the moiré structure in TBG varies …

The discovery of alternating superconducting and insulating ground states in magic angle
graphene has suggested an intriguing analogy with cuprate high-T c materials. Here we …

Close to a magical angle, twisted bilayer graphene (TBLG) systems exhibit isolated flat
electronic bands and, accordingly, strong electron localization. TBLGs have hence been …

We construct a two-channel scattering model for the triangular network of valley Hall states
in interlayer-biased minimally twisted bilayer graphene from symmetry arguments, and we …

We discuss plasmons of biased twisted bilayer graphene when the Fermi level lies inside
the gap. The collective excitations are a network of chiral edge plasmons (CEP) entirely …

The long-wavelength physics of monolayer graphene in the presence of periodic strain
fields has a natural chiral scattering network description. When the strain field varies slowly …
