Query: Helical superconducting edge modes from pseudo-Landau levels in graphene   We explore Andreev states at the interface of graphene and a superconductor
for a uniform pseudo-magnetic field. Near the zeroth-pseudo Landau level, we
find a topological transition as a function of applied Zeeman field, at which a
gapless helical mode appears. This 1D mode is protected from backscattering as
long as intervalley- and spin-flip scattering are suppressed. We discuss a
possible experimental platform to detect this gapless mode based on strained
suspended membranes on a superconductor, in which dynamical strain causes
charge pumping
