Abstract: We consider some scaling limits of a chain of oscillators, which is driven by some nonlinear potential and is perturbed by a stochastic noise. Then, the resulting Hamiltonian system can be interpreted as a multi-species system in the sense that there are more than one conservation laws. We study the corresponding fluctuations of these physical quantities by considering scaling limits with the help of the central limit theorem, and particularly see that some non-classical macroscopic phenomena can be observed.
