▎ 摘  要

We describe the lattice deformation in graphene under strain effect by considering the spacial-momenta coordinates do not commute. This later can be realized by introducing the star product to end up with a generalized Heisenberg algebra. Within such framework, we build a new model describing Dirac fermions interacting with an external source that is noncommutative parameter K dependent. The solutions of energy spectrum are showing Landau levels in similar way to the case of a real magnetic field applied to graphene. We show that some strain configurations can be used to explicitly evaluate K and then offer a piste toward its measurement. (C) 2020 Elsevier B.V. All rights reserved.
