Holographic Fermi surface at finite temperature in six-dimensional (2, 0) theory

Abstract

We analyzed two-point Green's functions of operators in six-dimensional (2, 0) theory dual to fermions in maximal gauged supergravity in seven dimensions at finite temperature. We have considered backgrounds with both the charge parameters nonzero as well as only one charge parameter nonzero. In the former case we find all the modes admit Fermi surface(s), while in the latter, some of the modes do not have a Fermi surface. We find backgrounds corresponding to nonzero expectation value of the scalar appearing in the dual operator give rise to Fermi surface(s).
