Density Matrix Renormalization Group Study of the Striped Phase in the 2D t − J Model

Year: 1998

Type: article

Abstract: Using the density matrix renormalization group, we study the 2D $t\ensuremath{-}J$ model at a hole doping of $x\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}\frac{1}{8}$ on clusters as large as $19\ifmmode\times\else\texttimes\fi{}8$. We find a striped phase consistent with recent neutron scattering experiments. We find that bond-centered and site-centered stripes have nearly the same energy, suggesting that in the absence of pinning effects the domain walls can fluctuate.
