内容記述 | We study the transfer of angular momentum of guided photons to a two-level atom with an electric quadrupole transition near an optical nanofiber. We show that the generation of the axial orbital torque of the driving guided field on the atom is governed by the internal-state selection rules for the quadrupole transition and by the angular momentum conservation law with the photon angular momentum given in the Minkowski formulation. We find that the torque depends on the photon angular momentum, the change in the angular momentum of the atomic internal state, and the quadrupole-transition Rabi frequency. We calculate numerically the torques for the quadrupole transitions between the sublevel M = 2 of the hyperfine-structure level 5 S 1 / 2 F = 2 and the sublevels M ′ = 0 , 1, 2, 3, and 4 of the hyperfine-structure level 4 D 5 / 2 F ′ = 4 of a 87 Rb atom. We show that the absolute value of the torque for the higher-order mode HE 21 is larger than that of the torque for the fundamental mode HE 11 except for the case M ′ − M = 2 , where the torque for the mode HE 21 is vanishing. | |||||
