Nieh-Yan anomaly: Torsional Landau levels, central charge, and anomalous thermal Hall effect

The Nieh-Yan anomaly is the anomalous breakdown of the chiral U(1) symmetry caused by the interaction between torsion and fermions. We study this anomaly from the point of view of torsional Landau levels. It was found that the torsional Landau levels are gapless, while their contributions to the chi...
