Abstract

Using the density matrix renormalization group, we study the 2D $t - J$ model at a hole doping of $x = \frac{1}{8}$ on clusters as large as $19 \times 8$ . 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.
