However, it is not yet clear whether dephasing can enhance transport in an interacting many-body system.
WebLocal movement of twin boundaries under such stresses produced extremely incoherent twin interfaces with a twinning dislocation spacing of ~4 Å, but when the twin boundary encountered large numbers of slip dislocations the mobility was retarded and the degree of incoherence reduced.
