Phase diagram of the Hubbard model at small doping and low temperature

TL;DR

This paper investigates the phase diagram of the Hubbard model at small doping and low temperature, but contains a correction notice regarding previous conclusions due to a technical error.

Contribution

The study aims to clarify the phase behavior of the Hubbard model under specific conditions, with a focus on low doping and temperature regimes.

Findings

Identification of phase boundaries in the Hubbard model

Correction of previous results due to technical error

Insights into low-temperature, small-doping regimes

Abstract

Warning: We have recently discovered a technical error in the paper cond-mat/9504032 and entitled here above, that invalidates part but not all of our conclusions. A corrected version will be soon put in.
