Title: The Hall effect:  what moves in a metal or a superconductor?

Speaker: Assa Auerbach, Department of Physics, Technion

Abstract:

The Hall resistivity has long been used to identify the mobile charge carriers in metals. 
However, transport theory has failed to explain several intriguing  ‘’Hall anomalies’’ in strongly correlated metals, superconductors, and thermal Hall effect in insulators.
Recent advances by our group include new formulas for the Hall coefficient, and a revised theory of flux flow in superconductors, which help us understand  the ‘’moving parts’’  in transport currents of these systems.
