Holographic Fermi surfaces in the six-dimensional (2, 0) theory

Abstract

We analyze the Fermi surface behavior of fermionic modes from a charged black hole background with two different charges arising in a truncated gauged supergravity theory in seven dimensions, which is dual to the six-dimensional (2, 0) theory. At zero temperature, we numerically solve equations for fermionic modes that do not couple to the gravitino. We find that each of the modes admits at least one Fermi surface. We find Fermi surfaces in both the Fermi-liquid and non-Fermi-liquid regimes.
