Abstract: (arXiv)
We explore five-dimensional and SO(6) gauged supergravities as frameworks for condensed matter applications. These theories contain charged (dilatonic) black holes and 2-forms which have non-trivial quantum numbers with respect to U(1) subgroups of SO(6). A question of interest is whether they also contain black holes with two-form hair with the required asymptotic to give rise to holographic superconductivity. We first consider the case, which contains a complex two-form potential which has U(1) charge . We find that a slight generalization, where the two-form potential has an arbitrary charge , leads to a five-dimensional model that exhibits second-order superconducting transitions of p-wave type where the role of order parameter is played by , provided . We identify the operator that condenses in the dual CFT, which is closely related to Super Yang-Mills theory with chemical potentials. Similar phase transitions between R-charged black holes and black holes with 2-form hair are found in a generalized version of the gauged supergravity Lagrangian where the two-forms have charge .- black hole: hair
