Anomalous Hall Conductivity as an Intrinsic Property of a Tight-Binding Graph
E. S. Andriyakhina, G. Lemut, P. W. Brouwer
In a ballistic system, the anomalous dc Hall response generically depends on microscopic details, including the geometric embedding of the orbitals and the precise implementation o…

Long-range spin-polarized Josephson effect in ballistic S/F/S junctions with precessing magnetization
E. S. Andriyakhina, M. Mansouri, M. Breitkreiz +1
We present a theory of ballistic N/F/S and S/F/S junctions with a uniformly precessing magnetization, which generates long-range equal-spin superconducting correlations [Takahashi…

Finite-frequency admittance and noise of a helical edge coupled to a magnet
Oliver Franke, Paula Koll, Peter G. Silvestrov +1
The exchange coupling of the helical edge state of a quantum spin-Hall insulator with an easy-plane magnet has no effect on its DC electrical conductance if the magnet's anisotropy…
