Abstract

In the context of holography applied to condensed matter
theory, I will present an analysis of transport properties of p-wave
superfluids by means of a gravity dual. Fluctuations modes in the SU(2)
Einstein-Yang-Mills theory are considered, and phenomenological implications
are derived. Due to the spatial anisotropy of the system, a non-universal shear
viscosity is obtained, along with a new coefficient associated to normal stress
differences. I will also discuss how the transport phenomena in this model is
related to the thermoelectric, flexoelectric and piezoelectric effects (mixing
of electric current, heat flux and mechanical stress), which have been observed
in some superconductors and crystal liquids.
