Title: Nernst Branes and the search for zero entropy black branes in supergravity


We study static black brane solutions in the context of N = 2 U(1) gauged supergravity in four and five dimensions. Using the formalism of first-order flow equations, we construct novel extremal black brane solutions including examples of Nernst branes, i.e. extremal black brane solutions with vanishing entropy density. We also discuss a class of non-extremal generalizations which is captured by the first-order formalism.

Based on work with Susanne Barisch-Dicke, Gabriel Cardoso, Michael Haack and Niels Obers.
