Identified regimes where pair production dominates charge transport.

Extended AdS/CFT results to non-conformal, higher-derivative theories.

Abstract

We investigate DC transport in a top-down construction of thermal QGP-like theories using a holographic M-theoretic background, incorporating quartic curvature corrections. The DC and Hall conductivities are computed from the Dirac-Born-Infeld (DBI) action of the corresponding type-IIA probe D6 flavor branes via the reality condition method proposed in arXiv:0708.1994 and arXiv:0705.3870. We further analyze pair-production contributions in the presence and absence of an external magnetic field and work out regimes where pair production dominates over charge carrier transport. These findings extend earlier AdS/CFT results to non-conformal, higher-derivative settings relevant to thermal QGP-like theories.
