摘要: The extended and standard t-J models are computationally studied on ladders planes, with emphasis the small J/t region. At couplings compatible photoemission results for undoped cuprates, half-doped stripes separating pi-shifted antiferromagnetic (AF) domains found, as in Tranquada's interpretation of neutron experiments. Our main result is that elementary stripe "building block" resembles properties one hole at J/t, robust AF correlations across induced by local tendency charge to separate from spin. This suggests seed already exists unusual insulating parent compound.
