We compare our results with a real experiment in the traveling case and we analyze how the average velocities and diffusions in the canonical directions depend on the potential parameters: a period time [tau] in the flashing ratchet and a velocity [ípsilon] in the traveling ratchet.5 p.application/pdfengcc-by-nc-nd (c) de la Torre, 2017http://creativecommons.org/licenses/by-nc-nd/3.0/es/Física matemàticaMecànica estadísticaTreballs de fi de grauMathematical physicsStatistical mechanicsBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
