What carries the Hall current in metals and superconductors? (Assa Auerbach / Seminar / LPT). – 6/02/2023, 14H

6 February 2023; 14h00 - 15h30

Assa Auerbach (Technion, Haïfa)

Seminar LPT, Tuesday February 6, 2023 – 14:00 – Seminar room, 3R1 – 3rd floor


The Hall coefficient has long been used to characterize the charge carriers as Fermi surface quasiparticles. However, unexpected Hall coefficient sign reversals and divergences (a.k.a. “Hall anomalies’’) are commonly observed in strongly correlated metals and flux flowing superconductors. The validity of band theory and Boltzmann equation is called into question.

I will describe recent advances in quantum transport theory which allows us to calculate the Hall coefficients from models of strong interactions, and to identify the “moving parts” which give rise to these Hall anomalies.
