  We show through simulation that quantum interference in non-sequential double
ionization can be used to control the recollision with subsequent ionization
(RESI) mechanism. This includes the shape, localization and symmetry of RESI
electron-momentum distributions, which may be shifted from a correlated to an
anti-correlated distribution or vice versa, far below the direct ionization
threshold intensity. As a testing ground, we reproduce recent experimental
results by employing specific coherent superpositions of excitation channels.
We examine two types of interference, from electron indistinguishability and
intra-cycle events, and from different excitation channels.
