Query: Reply to P. Ao's Comment on "Sign reversing Hall effect in atomically
  thin high temperature superconductors"   We respond to P. Ao's comment in arXiv:1907.09263, which suggests that vortex
many-body effects are the origin of Hall sign reversal in few-unit-cell thick
Bi-2212 cuprate crystals (Phys. Rev. Lett. 122, 247001 (2019)). Our
experimental results are incompatible with the theoretical predictions detailed
in Ao's comment.
