Abstract
We consider two interacting particles evolving in a one-dimensional periodi c structure embedded in a magnetic field. We show that the strong localizat ion induced by the magnetic field for particular values of the flux per uni t cell is destroyed as soon as the particles interact. We study the spectra l and dynamical aspects of this transition.
