Stripes disorder and correlation lengths in doped antiferromagnets
Stripes disorder and correlation lengths in doped antiferromagnets
For stripes in doped antiferromagnets, we find that the ratio of spin and charge correlation lengths ${\ensuremath{\xi}}_{s}/{\ensuremath{\xi}}_{c}$ provides a sharp criterion for determining the dominant form of disorder in the system. If stripes are disordered predominantly by topological defects then ${\ensuremath{\xi}}_{s}/{\ensuremath{\xi}}_{c}\ensuremath{\lesssim}1.$ In contast, if stripes correlations are disordered primarily by …
