# On topological transitions in metals

## TL;DR

This paper explores whether topological transitions in metals can be detected through transport measurements, finding that certain transport coefficients show clear discontinuities unaffected by bulk metallic transport.

## Contribution

It demonstrates that specific transport coefficients exhibit sharp discontinuities at topological transitions, which are not obscured by bulk metallic effects.

## Key findings

- Transport coefficients show discontinuous changes at topological transitions
- Discontinuities are robust against bulk metallic transport effects
- Certain signatures of topological transitions are detectable in transport measurements

## Abstract

We investigate if a sharp topological transition in a metal with a large Fermi surface may be detected in transport measurements. In particular, we address if a skew scattering and a side jump on elastic disorder in the bulk of such a metal masks signatures of the topological transition. We conclude that certain transport coefficients exhibit discontinuous changes across the transition. These discontinuities are not smeared or dwarfed by the bulk metallic transport in a broad range of parameters.
