Title
 The Hall effect: what moves in a metal or a superconductor?
Abstract The Hall resistivity has long been used to identify the ‘’moving parts’’ of electrical and thermal conductivity.
However, Boltzmann transport theory has failed to explain some intriguing ‘’Hall anomalies’’ in strongly correlated metals, superconductors, and large thermal Hall effect in insulators. Recent reformulations of the Kubo Hall conductivity and Hall coefficient and a linear response theory of flux flow in superconductors, helps us understand the Hall anomalies in these systems.
