Superconductivity of a Metallic Stripe Embedded in an Antiferromagnet

Yu. A. Krotov, D. -H. Lee, A. V. Balatsky

We study a simple model for the metallic stripes found in $L{a}_{1.6-x}N{d}_{0.4}S{r}_{x}Cu{O}_4$: two chain Hubbard ladder embedded in a static antiferromagnetic environments. We consider t…
