| Summary:
We theoretically study Rashba-Edelstein magnetoresistance (REMR) in a
two-dimensional electron gas (2DEG) system with Rashba and Dresselhaus
spin-orbit interactions. We consider a microscopic model of a junction system
composed of a ferromagnetic insulator and a 2DEG, and derive analytic
expressions for the spin and current densities in the 2DEG using the Boltzmann
equation, while taking into account dynamical contributions from magnons. Our
findings reveal that the sign of the REMR varies depending on the type of
interface. We also discuss the experimental relevance of our results.
