Description

We briefly report the recent discovery of collective oscillation of macroscopic variables in a metastable state in some Hamiltonian systems, using the meanfield XY model as an example. This periodic or quasiperiodic collective motion appears through Hopf bifurcation. The origin of the oscillation is explained, with self-consistent analysis of the distribution function, as the self-organization of a self-excited 'swing' state through the meanfield
