Abstract: In solids, the crystal field couples the electronic orbital degree of freedom to the lattice. This coupling suggests that an excitation of lattice dynamics could trigger the dynamics of orbital angular momentum of electrons, thereby… read more here.

Abstract: We report the detection of pure orbital currents generated by both coherent and thermal magnons in the magnetic insulator Bi-doped yttrium iron garnet (BiYIG). The pumping of orbital and spin currents is jointly investigated in… read more here.
