  bibo_abstract:
  - The surface states of 3D topological insulators in general have negligible quantum
    oscillations (QOs) when the chemical potential is tuned to the Dirac points. In
    contrast, we find that topological Kondo insulators (TKIs) can support surface
    states with an arbitrarily large Fermi surface (FS) when the chemical potential
    is pinned to the Dirac point. We illustrate that these FSs give rise to finite-frequency
    QOs, which can become comparable to the extremal area of the unhybridized bulk
    bands. We show that this occurs when the crystal symmetry is lowered from cubic
    to tetragonal in a minimal two-orbital model. We label such surface modes as 'shadow
    surface states'. Moreover, we show that the sufficient next-nearest neighbor out-of-plane
    hybridization leading to shadow surface states can be self-consistently stabilized
    for tetragonal TKIs. Consequently, shadow surface states provide an important
    example of high-frequency QOs beyond the context of cubic TKIs.@eng
