【 摘 要 】

We show that depending on the values of the coupling constants, two scenarios for the stationary behavior of a chain of interacting spasers may be realized: (1) all spasers are synchronized and oscillate with a unique phase or (2) a nonlinear autowave travels along the chain. In the latter scenario, the traveling wave is harmonic, unlike excitations in other known nonlinear systems. Due to the nonlinear nature of the system, any initial distribution of spaser states evolves into one of these steady states.
