  We extend the Berezinskii diagrammatic technique to one-dimensional
disordered spin systems, in which time-reversal invariance is broken due to a
spin-orbit coupling term inducing left-right asymmetric scattering. We then use
this formalism to theoretically describe the dynamics of the quantum boomerang
effect, a recently discovered manifestation of Anderson localization. The
theoretical results are confirmed by exact numerical simulations of wave-packet
dynamics in a random potential.
