We study the directional dependence of the coupling between a nanofiber-guided light field and a two-level atom with an electric quadrupole transition. We examine the situation where the nanofiber is aligned along theaxis, the atom lies on the fiber transverseaxis, the quantization axis for the atomic internal states is the other orthogonal transverseaxis, the atomic upper and lower levels are the magnetic sublevelsandof hyperfine-structure levels of an alkali-metal atom, and the field is in a quasilinearly polarized fundamental guided modewith the polarizationor. We find that the absolute value of the quadrupole Rabi frequency depends on the propagation direction of the light field in the cases of () and (). We show that the directional dependence of the coupling leads to the directional dependence of spontaneous emission into guided modes. We find that the directional dependence of the atom-field coupling in the case of quadrupole transitions is not entirely due to spin-orbit coupling of light: there are some other contributions resulting from the gradient of the spatial phase factor of the field.
