"General continuum model for twisted bilayer graphene and arbitrary smooth deformations" by Leon Balents has received the Select label. Warm congratulations to the author!



Moiré patterns can affect the low energy electronic structure in twisted bilayer graphene and provide an unprecedented platform for correlated electron physics. In this clear paper, the author uses a simple derivation of a continuum Hamiltonian to calculate the low energy electronic band structure. The original continuum model written in the momentum space is hard to use when lattice relaxation and strain effects come in. To solve this issue, the current paper derives the continuum model in real space, which can easily incorporate strain effects. With this new method, the author provides a unified method to study twisted graphene structures including all the important electronic structure physics. It may also be helpful for future studies of disorder effects in these systems.
