摘要：

Inspired by the recent observation that cuprate stripes tilt away from the crystal axis, we propose a new type of stripe phase in the large doping regime. This phase corresponds with a doped version of the x < 1/8 stripes. The topological excitations associated with this doping are fractionally charged kinks that make the stripes fluctuate and tilt. The experimental doping dependence of the tilt angle can be used to determine the fundamental charge quantum of the stripes.
