The particles perform a random walklike motion with antipersistent nature, showing for certain field parameters a crossover from subdiffusive to an enhanced diffusive behavior. We elucidate the stationary nature (no aging) of the subdiffusive process and stress its similarity with the random walk on a random walk model.5 p.application/pdfeng(c) American Physical Society, 2012Física de partículesParamagnetismeParticle physicsParamagnetisminfo:eu-repo/semantics/article6215682019-05-20info:eu-repo/semantics/openAccess
