Doped dimerized spin chains: Another path to superconductivity

TL;DR

This paper discusses doped dimerized spin chains as a potential route to superconductivity, but the authors withdrew it due to convergence issues and plan to submit an improved theory later.

Contribution

The paper introduces a theoretical approach to doped dimerized spin chains related to superconductivity, which is being revised for better convergence.

Findings

Initial approach not convergent at small doping

Authors plan to submit an improved theory

Focus on tJJ' model at small J/t

Abstract

This paper has been withdrawn by the authors, since we have come to believe that the present approach is not convergent at small doping. We will shortly submit an improved theory of the tJJ' model at small J/t in the dilute hole limit. This will be a new submission will go by a different submission number.
