## Description

- description: We have fabricated a high mobility device composed of a monolayer graphene
    flake sandwiched between two sheets of boron nitride. Conductance oscillations
    as functions of a back gate voltage and magnetic field were obtained to check
    for ergodicity. Non-linear dynamics analysis were used to study the behavior of
    n-type and p-type carriers. We have found that the carrier motion is chaotic and
    dissipative at low temperatures, which might be the reason for the observed non-ergodicity.
    The distribution of eigenvalues was estimated from the conductance oscillations
    with Gaussian kernels that reveal a Gaussian Unitary Ensemble for p-type carriers,
    possibly indicating a violation in time-reversal symmetry.
