C. Elphick, A. Hagberg and E. Meron, "A phase front instability in periodically forced oscillatory systems", Phys. Rev. Lett., vol. 80, no. 22, pp. 5007--5010, 1998


Multiplicity of phase states within frequency locked bands in periodically forced oscillatory systems may give rise to front structures separating states with different phases. A new front instability is found within bands where ωforcingsystem=2n (n>1). Stationary fronts shifting the oscillation phase by π lose stability below a critical forcing strength and decompose into n traveling fronts each shifting the phase by π/n. The instability designates a transition from stationary two-phase patterns to traveling n-phase patterns.
