D2-D8 model admits a numerical solution that corresponds to a charge density
wave and a spin density wave. Considering that as the background, we numerically solve
the Dirac equation for probe fermions. From the solution, we obtain the Green’s function
and study the behaviour of the spectral density. We begin with generic fermions and have
studied the formation of the Fermi surface and where it develops a gap. In addition, we
have incorporated an ionic lattice and study its effect on the Fermi surface. Then we
analysed the worldvolume fermions. In this particular model we do not find Fermi surface
for the dual operators.
