Query: Dynamic Mott gap from holographic fermions in geometries with
  hyperscaling violation   We investigate a dynamically generated Mott gap from holographic fermions in
asymptotically geometries with hyperscaling violation by employing a bulk
dipole coupling for the fermion field. We find that when the coupling strength
increases the spectral function first transfers to the negative frequency
region but soon redistributes to the positive region. A stable gap and two
bands emerges for all momentum when the coupling strength beyonds a critical
value. Generally, The upper band on the positive frequency axis is much sharper
than the lower band on the negative side. When the diploe coupling increases
further, the gap becomes larger and the up band still keeps sharp while the
lower band disperses and widens, concentrating on the small momentum region. We
also find that the bands will be smoothed out gradually with the increasing of
hyperscaling violation.
