Hall effect in cuprates with an incommensurate collinear spin-density wave

The presence of incommensurate spiral spin-density waves (SDW) has been proposed to explain the p (hole doping) to 1+p jump measured in the Hall number nH at a doping p∗. Here we explore incommensurate collinear SDW as another possible explanation of this phenomenon, distinct from the incommensurate spiral SDW proposal. We examine the effect of different SDW strengths and wave vectors, and we find that the nH∼p behavior is hardly reproduced at low doping. Furthermore, the calculated nH and Fermi surfaces give characteristic features that should be observed; thus, the lack of these features in experiment suggests that the incommensurate collinear SDW is unlikely to be a good candidate to explain the nH∼p observed in the pseudogap regime.
