Resumen:
Quantum tra jectories defined in the de Broglie-Bohm theory provide a causal
way to interpret physical phenomena. In this letter, we use this formalism to analyze the short-
time dynamics induced by unstable periodic orbits in a classically chaotic system, a situation
in which scars are known to play a very important role. We find that the topologies of the
quantum orbits are much more complicated than that of the scarring and associated periodic
orbits, since the former have quantum interference built in. Thus scar wave functions are
necessary to analyze the corresponding dynamics. Moreover, these topologies imply different
return routes to the vicinity of the initial positions, and this reflects in the existence of different
contributions in each peak of the survival probability function.
