Thermoelectric Conductivities at Finite Magnetic Field and the Nernst Effect

Understand

We study the thermoelectric conductivities of a strongly correlated system in the presence of a magnetic field by the gauge/gravity duality.

• We consider a class of Einstein-Maxwell-Dilaton theories with axion fields imposing momentum relaxation.
• General analytic formulas for the direct current(DC) conductivities and the Nernst signal are derived in terms of the black hole horizon data.
• For an explicit model study, we analyse in detail the dyonic black hole modified by momentum relaxation.
