Transport through dynamic pseudogauge fields and snake states in a Corbino geometry

We propose a Corbino-disk geometry of a graphene membrane under out-of-plane strain deformations as a convenient path to detect pseudomagnetic and electric fields via electronic transport. The threefold symmetric pseudomagnetic field changes sign six times as a function of angle, leading to snake states connecting the inner and outer contacts and to nearly quantized transport. For dynamical strain obtained upon AC gating, the system supports an AC pseudoelectric field which, in the presence of the pseudomagnetic field, produces a net electronic charge current in the absence of an external voltage via a pseudo-Hall effect.
