The vortex Hall effect in superconductors

AbstractThe dissipative effect of vortex motion is almost omnipresent in superconductivity research and is commonly associated with a voltage drop along the current direction. It is not so evident that also a transverse voltage appears in this situation that resembles the Hall effect and is, thus, frequently called vortex Hall effect. Due to the complicated equation of motion of a vortex in a real system with pinning and other forces, and the even more subtle situation in a vortex ensemble, the vortex Hall effect is not well understood. In particular, in the copper-oxide superconductors, the Hall effect in the superconducting state exhibits several anomalies that are in contrast to conventional theoretical predictions. I shall review some of these puzzling effects that deserve further attention and research efforts.
