“…The striped superconductor (SSC) is a special kind of high-T c superconductors characterized by the presence of pair density waves (PDW), which is described by a spatially modulated order parameter [1][2][3][4][5]. The SSC phase plays a key role in understanding the mechanism of high-temperature superconductivity because in many materials SSC appears as the intertwined phase of charge density wave (CDW) phase and the uniform superconducting (SC) phase.…”

We construct a holographic model describing the striped superconductor (SSC), which is characterized by the presence of pair density waves (PDW). We explicitly demonstrate that the SSC phase is implemented as the intertwined phase of charge density waves (CDW) order and uniform superconducting (SC) order. The interplay of PDW order, CDW order as well as the uniform SC order in SSC phase is studied. It is found that the PDW order is prominent when both CDW order and uniform SC order are balanced. The critical temperature of CDW becomes higher in the presence of the uniform SC order, but its charge density amplitude is suppressed. On the other hand, the SC order is not sensitive to the presence of CDW order. We also demonstrate that among all the possible solutions, the black hole in SSC phase has the lowest free energy and thus is thermodynamically favored.

“…The team's technique, called Auger-mediated positron surface sticking (AMPS), is not the first that can determine the electronic states of a material's top-most layer. So far, several such methods have been created, the best known being spectroscopic-imaging scanning tunneling microscopy [2]. In this method, Fourier transformation of the real-space image allows researchers to measure the surface local DOS and to map the electronic states in k-space.…”
