Departamento de Qu´imica-F´isica, Universidad del Pa´is Vasco, Apartado 644, 48080 Bilbao, Spain(Dated: May 27, 2008)The momentum distribution of an expanding cloud of one-dimensional hard-core anyons is stud-ied by an exact numerical approach, and shown to become indistinguishable from that of a non-interacting spin-polarized Fermi gas for large enough times (dynamical fermionization). We alsoconsider the expansion of one-dimensional anyons with strongly attractive short-range interactionssuddenly released from a parabolic external potential, and find that momentum distribution ap-proaches that of its dual system, the ideal Bose gas (dynamical bosonization). For both processesthe characteristic time scales are identified, and the effect of the initial confinement is analyzedcomparing the dynamics associated with both harmonic and hard-wall traps.
