요약 | In light-matter interaction, the conservation law of angular momentum requires the transfer of angular momentum of light to matter, which consequently couples light polarization to various state variables of materials, such as mechanical mo- tio |
요약 | First, in an integrated optomechanical device, the spin angular momentum of light propagating in a waveguide is revealed through the use of optical torque to ex- cite torsional motion of the device. The quantitative optical torque measurement co |
요약 | Second, the coupling of light polarization and electron spin orientation is in- vestigated in the optical excitation of surface states in a 3D topological insu- lator Bi2Se3. The angular momentum conservation manifests itself in the spin- depend |
요약 | Finally, we present the all-optical manipulation of magnetic order in ferrimag- netic alloy Gd(FeCo) using sub-picosecond laser pulses as the ultrafast stimuli. The instantaneous heating of the electron temperature due to light absorption trigge |
