New Model and Numerical Test of a High Temperature Pairing Mechanism in Stripes

Abstract

We introduce a new model and mechanism of high temperature pairing in stripes. We propose a way to unambiguously test it by numerical simulations. For example, the implementation of our mechanism in a 6-leg t-J ladder model has the effect of making the spin gap of the doped 6-leg ladder be about 4 times bigger than the spin gap of the same ladder at half filling.
