Anisotropic Fermi surface from holography

Understand

We investigate the probe holographic fermions by using an anisotropic charged black brane solution.

• We derive the equation of motion of probe bulk fermions with one Fermi momentum along the anisotropic and one along the isotropic directions.
• We then numerically solve the equation and analyze the properties of Green function with these two momentums.
• We find in this case the shape of Fermi surface is anisotropic.
