Abstract

We investigate the hole spin-3/2 relaxation process induced by nonadiabatic stochastic modulations of the instantaneous Luttinger Hamiltonian. The theory allows to consider fluctuations of both the direction and the magnitude of a hole wave vector in all regimes of momentum scattering: from collision-dominated to ballistic.
