Quantum Transport Simulations for Strained Graphene

Quantum transport simulations for experimentally sized graphene have been shown possible using the scalable tight-binding model. Over the past decade, the scaling method has been widely applied in the scope of ballistic transport in clean graphene, including graphene superlattices. Very recently, we have further generalized the scaling method to cover the scope of strained graphene], i.e., graphene lattices deformed by certain displacement fields. As predicted in early studies, strained graphene due to properly designed displacement fields exhibit energy spectra reminiscent of graphene under a magnetic field, known as the pseudomagnetic field. This talk conveys the main ideas, including scaling invariant pseudomagnetic fields and transport simulations in mesoscopic strained graphene, and ends with reproducing the transport features reported in a recent experiment.
