Chiral Anomaly Trapped in Weyl Metals: Nonequilibrium Valley Polarization at Zero Magnetic Field

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Pablo M. Perez-Piskunow, Nicandro Bovenzi, Anton R. Akhmerov, Maxim Breitkreiz, | Summary: In Weyl semimetals the application of parallel electric and magnetic fields leads to valley polarization — an occupation disbalance of valleys of opposite chirality — a direct consequence of the chiral anomaly. In this […]
