Abstract:
In a numerical experiment, it was found that in a chain of Raleigh oscillators with a nonlinear connection between them, at least three localized stationary breathers modes may exist: non-mobile, “slow” and “fast” dissipative breathers. The dynamics of the chain elements depends on the ratio of characteristic time scales of the system which determined by the frequency of oscillators and the rigidity of the connection between them. Considered system is multistable.
Keywords:
chain of oscillators, active particles, nonlinear system, nonlinear coupling, dissipative discrete breather.
