We analyze a description of twisted graphene bilayers, that incorporates deformation of the layers due to the nature modern interlayer potentials, and a modification of the hopping parameters between layers in the light of the classic Slonczewski-Weiss-McClure parametrisation. We shall show that flat bands result in all cases, but that their nature can be rather different. We will show how to construct a more general reduction to a continuum model, and show that even though such a model can be… 
Exact continuum model for low-energy electronic states of twisted bilayer graphene
We introduce a physically motivated minimal model for the electronic structure of twisted bilayer graphene (tBLG), which incorporates the crucial role of lattice relaxation. Our model, based on $k
Flat bands, strains, and charge distribution in twisted bilayer h−BN
We study the effect of twisting on bilayer graphene. The effect of lattice relaxation is included; we look at the electronic structure, piezo-electric charges and spontaneous polarisation. We show
Lattice Deformation, Low Energy Models and Flat Bands in Twisted Graphene Bilayers.
Twisted graphene bilayers show a complex electronic structure, further modified by interaction effects. The main features can be obtained from effective models, which make use a few phenomenological
Constrained random phase approximation of the effective Coulomb interaction in lattice models of twisted bilayer graphene
Recent experiments on twisted bilayer graphene show the urgent need for establishing a low-energy lattice model for the system. We use the constrained random phase approximation to study the
Twisted Trilayer Graphene: A Precisely Tunable Platform for Correlated Electrons.
It is demonstrated that the tTLG system exhibits a wide range of magic angles at which VHS merge and that the density of states has a sharp peak at the charge-neutrality point through two distinct mechanisms: the incommensurate perturbation of twisted bilayer graphene's flatbands or the equal hybridization between two bilayer moiré superlattices.
Twistronics versus straintronics in twisted bilayers of graphene and transition metal dichalcogenides
Several numerical studies have shown that the electronic properties of twisted bilayers of graphene (TBLG) and transition metal dichalcogenides (TMDs) are tunable by strain engineering of the
Obstruction and Interference in Low-Energy Models for Twisted Bilayer Graphene.
This work finds that a careful analysis of the electron density produced by backscattering of Bloch waves from an impurity potential localized on the moiré superlattice scale can be used to tightly constrain the analytic form of the appropriate low-energy theory.
The emergence of one-dimensional channels in marginal-angle twisted bilayer graphene
We generalize the continuum model for Moiré structures made from twisted graphene layers, in order to include lattice relaxation and the formation of channels at very small (marginal) twist angles.
Microscopic pairing mechanism, order parameter, and disorder sensitivity in moiré superlattices: Applications to twisted double-bilayer graphene
Starting from a continuum-model description, we develop a microscopic weak-coupling theory for superconductivity in twisted double-bilayer graphene. We study both electron-phonon and entirely

Single-electron gap in the spectrum of twisted bilayer graphene
We investigate the gap in the single-electron spectrum of twisted bilayer graphene. In a perfect infinite lattice of a twisted bilayer, the gap varies exponentially in response to weak changes of the
Non-Abelian gauge potentials in graphene bilayers.
Graphene bilayers' single-particle physics is governed by a non-Abelian gauge potential arising in the low-energy electronic theory due to the coupling between layers, which gives rise to a potential that spatially confines states at zero energy in particular regions of the moiré patterns.
All Magic Angles in Twisted Bilayer Graphene are Topological.
This work proves, using an approximate low-energy particle-hole symmetry, that the gapped set of bands that exist around all magic angles have a nontrivial topology stabilized by a magnetic symmetry, provided band gaps appear at fillings of ±4 electrons per moiré unit cell.
