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

TL;DR

This paper presents a novel model for high temperature pairing in stripe phases, supported by numerical simulations showing significant enhancement of the spin gap in a 6-leg t-J ladder, indicating a potential mechanism for high-temperature superconductivity.

Contribution

It introduces a new high temperature pairing mechanism in stripe phases and proposes a numerical test to verify its effects.

Findings

Spin gap increases by about 4 times in doped 6-leg ladder with the new mechanism.

Numerical simulations confirm the effectiveness of the proposed pairing mechanism.

The model provides a testable prediction for high temperature superconductivity in stripe materials.

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.
