Anomalous Hall effect from a non-Hermitian viewpoint
Hiroki Isobe, Naoto Nagaosa
Non-Hermitian descriptions often model open or driven systems away from the equilibrium. Nonetheless, in equilibrium electronic systems, a non-Hermitian nature of an effective Hami…

Toroidal Scattering and Nonreciprocal Transport by Magnetic Impurities
Hiroki Isobe, Naoto Nagaosa
We propose the second-order response of metals in an electric field induced by magnetic impurities which locally break inversion symmetry. The impurities with toroidal moments scat…

Nodal Arc in Disordered Dirac Fermions: Connection to Non-Hermitian Band Theory
Michał Papaj, Hiroki Isobe, Liang Fu
We show that Dirac fermion systems in two dimensions generally exhibit disorder-induced nodal arc replacing the nodal point and tilted Dirac cone, provided that the two components…
