## Description

- description: Due to Landau quantization, the conductance of two-dimensional electrons
    exposed to a perpendicular magnetic field exhibits oscillations that generate
    a fan of linear trajectories when plotted in the parameter space spanned by density
    and magnetic field. This fan looks identical irrespective of the electron dispersion
    details that determine the field dependence of the Landau level energy. This is
    no surprise, since the position of conductance minima solely depends on the level
    degeneracy which is linear in flux. The fractal energy spectrum that emerges within
    each Landau band when electrons are also exposed to a two-dimensional superlattice
    potential produces numerous additional oscillations, but they too create just
    linear fans for the same reason. Here, we report on conductance oscillations of
    graphene electrons exposed to a moiré potential that defy this general rule of
    flux linearity and attribute the anomalous behavior to the simultaneous occupation
    of multiple minibands and magnetic breakdown.
