Specifically, it is deduced from the criticality scenario giving rise to ratchet universality as well as from an approach based on Fokker\u2013Planck\u2019s equation. Numerical experiments confirmed the existence of such exact universal excitation waveform in the context of a driven overdamped Brownian particle subjected to a periodic potential. While the universality scenario holds regardless of the waveform of the periodic vibratory excitations involved, it is shown that the enhancement of directed ratchet transport is optimal when the impulse transmitted by those excitations (time integral over a half-period) is maximum. <\/jats:p>","DOI":"10.1142\/s0218127421501091","type":"journal-article","created":{"date-parts":[[2021,6,18]],"date-time":"2021-06-18T04:18:28Z","timestamp":1623989908000},"page":"2150109","source":"Crossref","is-referenced-by-count":7,"title":["Exact Universal Excitation Waveform for Optimal Enhancement of Directed Ratchet Transport"],"prefix":"10.1142","volume":"31","author":[{"given":"Ricardo","family":"Chac\u00f3n","sequence":"first","affiliation":[{"name":"Departamento de F\u00edsica Aplicada, E.
