| Popis: | SM thankfully acknowledges the financial assistance received from Science and Engineering Research Board (SERB), India (project file no. CRG/2019/002167). 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. Department of Science & Technology (India) Science Engineering Research Board (SERB), India CRG/2019/002167 |
