We simulate the dynamics of a non-equilibrium zero-temperature Random Field Ising Model in two dimensions. Critical behaviour is analyzed from numerical simu-lations through scaling techniques. In addition, analytical approaches are brie y discussed.5 p.application/pdfengcc-by-nc-nd (c) Ortiz Castillo, 2014http://creativecommons.org/licenses/by-nc-nd/3.0/es/Matèria condensadaFenòmens crítics (Física)Treballs de fi de grauCondensed matterCritical phenomena (Physics)Bachelor's thesesDisorder-Induced Critical Phenomena in the 2-D Random Field Ising Modelinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
