Comment on Sign-Reversing Hall Effect in Atomically Thin High-Temperature Bi type Superconductors

Abstract

What is the fundamental reason for Hall Anomaly in Type II Superconductors: Independent Vortex Dynamics Effect or a Manifestation of Vortex Many-Body Effect? For a long time researchers in this field had not realized the importance of vortex many-body effects in the understanding of the so-called anomalous Hall effect. In this note I give a brief account of the situation in the light of a recent Phys Rev Lett.
