Hall effect in cuprates with incommensurate spin-density wave

arXiv:1708.09465 · doi:10.1103/PhysRevB.96.205132

Abstract

The presence of incommensurate spiral spin-density waves (SDW) has been proposed to explain the (hole doping) to jump measured in the Hall number at a doping . Here we explore {\it collinear} incommensurate SDW as another possible explanation of this phenomenon, distinct from the incommensurate {\it spiral} SDW proposal. We examine the effect of different SDW strengths and wavevectors and we find that the behavior is hardly reproduced at low doping. The calculated 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 observed in the pseudogap regime.
