dc.description.abstract |
In the context of applications of the AdS/CFT correspondence to condensed
matter physics, we compute conductivities for field theory duals of dyonic planar black holes
in 3+1-dimensional Einstein-Maxwell-dilaton theories at zero temperature. We combine
the near-horizon data obtained via Sen’s entropy function formalism with known expressions
for conductivities. In this way we express the conductivities in terms of the extremal
black hole charges. We apply our approach to three different examples for dilaton theories
for which the background geometry is not known explicitly. For a constant scalar potential,
the thermoelectric conductivity explicitly scales as αxy ∼ N3/2
, as expected. For the
same model, our approach yields a finite result for the heat conductivity κ/T ∝ N3/2
even
for T → 0. |
