Query: Correlations in the elastic Landau level of spontaneously buckled
  graphene   Electronic correlations stemming from nearly flat bands in van der Waals
materials have demonstrated to be a powerful playground to engineer artificial
quantum matter, including superconductors, correlated insulators and
topological matter. This phenomenology has been experimentally observed in a
variety of twisted van der Waals materials, such as graphene and dichalcogenide
multilayers. Here we show that spontaneously buckled graphene can yield a
correlated state, emerging from an elastic pseudo Landau level. Our results
build on top of recent experimental findings reporting that, when placed on top
of hBN or NbSe$_2$ substrates, wrinkled graphene sheets relax forming a
periodic, long-range buckling pattern. The low-energy physics can be accurately
described by electrons in the presence of a pseudo-axial gauge field, leading
to the formation of sublattice-polarized Landau levels. Moreover, we verify
that the high density of states at the zeroth Landau level leads to the
formation of a periodically modulated ferrimagnetic groundstate, which can be
controlled by the application of external electric fields. Our results indicate
that periodically strained graphene is a versatile platform to explore emergent
electronic states arising from correlated elastic Landau levels.
