Coexistence of two vector order parameters: a holographic model for ferromagnetic superconductivity

Understand

We study a generalization of the standard holographic p-wave superconductor featuring two interacting vector order parameters.

• Basing our argument on the symmetry and linear response properties of the model, we propose it as a holographic effective theory describing a strongly coupled ferromagnetic superconductor.
• We show that the two order parameters undergo concomitant condensations as a manifestation of an intrinsically interlaced electric/magnetic dynamics.
• Such intertwined dynamics is confirmed by the study of the transport properties.
