Origin of the Hall conductivity below the vortex-lattice melting in twinned single crystal YBCO

TL;DR

This paper investigates the origin of Hall conductivity behavior below the vortex-lattice melting point in twinned YBCO crystals, challenging existing theories and providing new insights into vortex dynamics.

Contribution

It offers a critical analysis of current theoretical explanations and presents arguments for an alternative understanding of Hall conductivity in high-temperature superconductors.

Findings

Current theories fail to fully explain the observations.

The paper proposes new arguments for the vortex dynamics.

Challenges existing explanations of Hall conductivity behavior.

Abstract

In his the Comment, P. Ao affirms that his vortex many-body theory explains the observations reported in G. D'Anna et al., Phys. Rev. Lett. 81, 2530 (1998). Indeed, we provide here some arguments to show the lack of a satisfactory explanation within the known theoretical frameworks.
