dc.descriptionWe perform a many-body investigation of the spin dephasing in $n$-typed InAs quantum wells under moderate magnetic fields in the Voigt configuration by constructing and numerically solving the kinetic Bloch equations. We obtain the spin dephasing time due to the Rashba effect together with the spin conserving scattering such as the electron-phonon, the electron-nonmagnetic impurity as well as the electron-electron Coulomb scattering. By varying the initial spin polarization, temperature, impurity density, applied magnetic field and the interface electric field, we are able to study the spin dephasing time under various conditions. For the electron density and quantum well width we study, the many-body effect dominates the spin dephasing. Moreover, we find an anomalous resonance peak in the spin dephasing time for high initial spin polarization under moderate magnetic fields.
