▎ 摘　　要

We investigate the influence of gauge fields induced by strain on the supercurrent passing through the graphene-based Josephson junctions. We show that, in the presence of a constant pseudomagnetic field B-s originating from an arc-shape elastic deformation, the Josephson current is monotonically enhanced. This is in contrast with the oscillatory behavior of supercurrent (known as Fraunhofer pattern) caused by real magnetic fields passing through the junction. The absence of oscillatory supercurrent originates from the fact that strain-induced gauge fields have opposite directions at the two valleys due to the time-reversal symmetry. Subsequently the Aharonov-Bohm phases due to B-s cancel out between electron and hole components of the current carrying Andreev bound states. Nevertheless, we find another phase factor coming from the pseudomagnetic fields which rotates the pseudospin and is in fact responsible for the enhancement of Josephson currents. When both magnetic and pseudomagnetic fields are present, Fraunhofer-like oscillations as a function of the real magnetic field flux are found. Intriguingly, the combination of two kinds of gauge fields results in two special fingerprints in the local supercurrent density: (i) strong localization of the Josephson current density with more intense maximum amplitudes; (ii) appearance of the inflated vortex cores-finite regions with almost diminishing Josephson currents-whose sizes increase by increasing B-s. These findings reveal unexpected interference signatures of pseudomagnetic fields in graphene SNS junctions which can cause a twist in the investigations on strain-induced gauge fields.
