Stripes on a 6-Leg Hubbard Ladder
Steven R. White, D.J. Scalapino

TL;DR
This paper investigates stripe formation in a 7x6 Hubbard ladder with 4 holes, revealing that stripes form for a range of interaction strengths, with characteristics varying from broad to well-defined.
Contribution
It provides the first detailed analysis of stripe formation in n-leg Hubbard ladders, extending understanding beyond the well-studied t-J models.
Findings
Stripes form for U/t between 6 and 20.
Stripe features are broad at lower U/t (~3-4).
Clear stripe formation occurs at higher U/t values.
Abstract
While DMRG calculations find stripes on doped n-leg t-J ladders, little is known about the possible formation of stripes on n-leg Hubbard ladders. Here we report results for a 7x6 Hubbard model with 4 holes. We find that a stripe forms for values of U/t ranging from 6 to 20. For U/t ~ 3-4, the system exhibits the domain wall feature of a stripe, but the hole density is very broadened.
