Popis:	We investigate the dynamical evolution of strongly interacting anyons confined in a weak harmonic trap using the exact anyon-fermion mapping method. The density profiles, momentum distribution, and the reduced one-body density matrix are obtained for different statistical parameters. The density profiles of anyons display the same behaviors irrespective of statistical parameter during the evolution. As the harmonic trap is turned off suddenly, the momentum distributions exhibit the symmetric fermion-like behaviour in the long time evolution. As the trap frequency is quenched, the momentum distribution exhibit an asymmetry breath mode during the evolution. The reduced one-body density matrix show the dynamical symmetry broken and reproduced behaviour. Comment: 7 pages, 6 figures
