  "abstract": "We theoretically consider the effect of the vertex correction in spin pumping from a ferromagnetic insulator (FI) into a two-dimensional electron gas (2DEG) in which the Rashba and Dresselhaus spin-orbit interactions coexist. We calculate the enhancement of Gilbert damping and the shift of the resonant frequency by solving the vertex functions. Although the vertex correction usually affects the results moderately, elastic spin flipping is strongly suppressed when the two spin-orbit interactions compete with each other.",
