Finding conditions that support synchronization is a fertile and active area
of research with applications across multiple disciplines. Here we present and
analyze a scheme for synchronizing chaotic dynamical systems by transiently
uncoupling them. Specifically, systems coupled only in a fraction of their
state space may synchronize even if fully coupled they do not. Although, for
many standard systems, coupling strengths need to be bounded to ensure
synchrony, transient uncoupling removes this bound and thus enables
synchronization in an infinite range of effective coupling strengths. The
presented coupling scheme thus opens up the possibility to induce synchrony in
(biological or technical) systems whose parameters are fixed and cannot be
modified continuously.Comment: 5 pages, 6 figure
