Topological transitions in metals

Research output: Contribution to journalArticlepeer-review


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.
