  "abstract": "We study the impacts of the magnetic field direction on the spin dynamics in a one-dimensional quantum dot with strong spin-orbit coupling. The energy spectrum and the corresponding eigen- functions in the quantum dot are exactly obtained. We find that no matter how large the spin-orbit coupling is, the electric-dipole spin transition rate as a function of the magnetic field direction always has a {\\pi} periodicity. However, the phonon-induced spin relaxation rate as a function of the magnetic field direction has a {\\pi} periodicity only in the weak spin-orbit coupling regime and a 2{\\pi} periodicity in the strong spin-orbit coupling regime.",
