This is a review of electronic quantum interference in mesoscopic ring
structures based on graphene, with a focus on the interplay between the
Aharonov-Bohm effect and the peculiar electronic and transport properties of
this material. We first present an overview on recent developments of this
topic, both from the experimental as well as the theoretical side. We then
review our recent work on signatures of two prominent graphene-specific
features in the Aharonov-Bohm conductance oscillations, namely Klein tunneling
and specular Andreev reflection. We close with an assessment of experimental
and theoretical development in the field and highlight open questions as well
as potential directions of the developments in future work.
