Holographic Fermi surfaces in charge density wave from D2-D8

Holographic Fermi surfaces in charge density wave from D2-D8

Abstract 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 spectra...
