摘要：

We study the influence of disorder and lattice effects on the striped phase and the incommensurate spin fluctuations of the cuprates and nickelates. Starting from a phenomenological model of a discrete quantum string on a lattice with disorder, we derive the renormalization group equations in leading order in the lattice and disorder strength. Three regimes are identified: the quantum membrane phase, the flat phase pinned by the lattice, and the disorder pinned phase. We compare our results with measurements on nickelates and cuprates and find good agreement.
