Краткий обзор статьи: Using the density matrix renormalization group (DMRG), we study the 2D t-J model at a hole doping of x=1/8 on clusters as large as 19×8. We find a striped phase which is 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.
