Microscopic scenario for striped superconductors

We argue that the superconducting state found in high-T-c cuprates is inhom ogeneous with a corresponding inhomogeneous superfluid density. We introduc e two classes of microscopic models which capture the magnetic and supercon ducting properties of these strongly correlated materials. We start from a generalized t-J model, in which appropriate inhomogeneous terms mimic strip es. We find that inhomogeneous interactions that break magnetic symmetries are essential to induce substantial pair binding of holes in the thermodyna mic limit. We argue that this type of model reproduces the ARPES and neutro n scattering data seen experimentally.
