Abstract
The electron (hole) spin–photon interaction is studied in an asymmetrical InSb (Ge) nanowire quantum dot. The spin–orbit coupling in the quantum dot mediates not only a transverse spin–photon interaction, but also a longitudinal spin–photon interaction due to the asymmetry of the confining potential. Both the transverse and the longitudinal spin–photon interactions have non-monotonic dependence on the spin–orbit coupling. For realistic spin–orbit coupling in the quantum dot, the longitudinal spin–photon interaction is much (at least one order) smaller than the transverse spin–photon interaction. The order of the transverse spin–photon interaction is about 1 nm in terms of length |zeg| , or 0.1 MHz in terms of frequency eE0|zeg|/h for a moderate cavity electric field strength E0=0.4 V m−1.
