סמינר בחומר מעובה: Hall anomalies in metals and superconductors
Assa Auerbach, Technion
The Hall effect has long been used to identify the sign and density of charge carriers in metals.
However, traditional Fermi-liquid and Boltzmann transport theory fail to explain ‘’Hall anomalies’’ which have been observed in strongly correlated and multiband metals and flux flowing superconductors. I will review our recent advances in magneto-transport theory, including new formulas for Hall coefficients allow us to explain Hall anomalies near the Mott insulator and Hall sign reversals in flux flow regimes of superconductors.
