Abstract:

One of the differences between conventional superconductors and high temperature superconductors is that the normal states of the conventional superconductors are well described by Fermi liquid, whose only (weak coupling) instability is to superconductivi​ty. By contrast, the normal states of high temperature superconductors​, such as cuprates and iron pnictides, are highly correlated and thus, exhibit other low temperature orders which interact strongly with superconductivi​ty. One of the prominent orders is the unidirectional charge density wave ``stripe" order. It is therefore important to understand the nature of the interplay between superconductivi​ty and the stripe order in the presence of strong correlation. I study the effects of the stripe order on the superconducting transition temperature of the strongly correlated superconductor using holography or gauge/gravity duality. In this talk I will present a holographic model of strongly coupled striped superconductors​.
