We show that initially localized and uncorrelated two-particles quantumwavepackets evolving in a one-dimensional discrete lattice become stronglyentangled while drifting under the action of an harmonic AC field resonant withdoubled Bloch oscillations promoted by a static DC field. Although partialentanglement is achieved when the AC field is resonant with the single-particleBloch oscillations, it is strongly limited by the survival of anti-correlatedunbounded states. We further show that the phase dependence of the wavepacketcentroid velocity is similar to the semiclassical behavior depicted by asingle-particle. However, the drift velocity exhibits a non-trivialnon-monotonic dependence on the interaction strength, vanishing in the limit ofuncorrelated particles, that unveils its competing influence on unbounded andbounded states.
