  Holographic properties of a finite density fermion system have been shown to
exhibit many interesting behaviours which can be observed in future. In this
paper, we study low energy fermion properties in the framework of the
holographic Mott-Insulator system. We study the nature of the Fermi surface and
its evolution by tuning two types of dipole couplings in the bulk. We further
introduce translational symmetry breaking complex scalar field, which is
assumed to couple with the holographic fermions. The symmetry breaking
background induced by the scalar field is known as Q-lattice. We calculate the
fermion spectral function, which captures the low energy behaviour of the
system. By tuning the dipole parameters and the non-normalizable component of
the scalar field, we observe interesting phenomena such as spectral weight
transfer, Fermi surface smearing, which has already been reported in various
real condensed matter experiments.
