Spin Current Generation by a Surface Plasmon Polariton
Theodorus Jonathan Wijaya, Daigo Oue, Mamoru Matsuo +5
Surface plasmon polariton (SPP) is an electromagnetic wave which is tightly localised beyond the diffraction limit at metallic surfaces. Recently, it is theoretically proposed that…
Optically induced electron spin currents in the Kretschmann configuration
Daigo Oue, Mamoru Matsuo
We investigate electron spin currents induced optically via plasmonic modes in the Kretschmann configuration. By utilising the scattering matrix formalism, we take the plasmonic mo…
Effects of surface plasmons on spin currents in a thin film system
Daigo Oue, Mamoru Matsuo
We propose and analyze surface-plasmon-driven electron spin currents in a thin metallic film. The electron gas in the metal follows the transversally rotating electric fields of th…
Electron spin transport driven by surface plasmon polariton
Daigo Oue, Mamoru Matsuo
We propose a mechanism of angular momentum conversion from optical transverse spin in surface plasmon polaritons (SPPs) to conduction electron spin. Free electrons in the metal fol…
Electromagnetism at finite temperature: a density operator approach
Daigo Oue
In order to analyse classical electromagnetism in a medium at finite temperature we introduce `an optical density operator', and reformulate Maxwell's equations with the operator,…
