Boundary Kerr Signatures of the Interband-Coherence Hall Effect

We identify a Hall response carried by optically induced interband coherence rather than by a non-equilibrium band population.

We identify a Hall response carried by optically induced interband coherence rather than by a non-equilibrium band population. In a weakly doped zinc-blende semiconductor, a longitudinal dc field drives a transverse flux of the conduction--valence coherence created by near-gap…
