Recently, a holographic description of cosmic preheating is about to be proposed. This aims to study the process of preheating at strong coupling where the perturbation theory has broken down. A model of holographic superconductor inspired by condensed matter theory in terms of two superfluids in five dimensional AdS background was adopted, which can mimic a cosmic system of the inflation strongly coupled with a fermionic matter field. The corresponding cosmological implications can be translated by performing a conformal transformation from the Minkowski boundary to an FRW boundary.
