For a not too large field the density of states g(¿) develops localized soft plastic modes and reaches zero as ¿4 (for large fields a gap appears). When we perturb the system adding a force along the softest mode, one reaches very similar minima of the energy, separated by small barriers, that appear to be good candidates for classical two-level systems. 000041810 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/FIS2012-35719-C02$$9info:eu-repo/grantAgreement/EC/FP7/247328/EU/Critical Phenomena in Random Systems/CRIPHERASY 000041810 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000041810 590__ $$a7.645$$b2015 000041810 591__ $$aPHYSICS, MULTIDISCIPLINARY$$b6 / 79 = 0.076$$c2015$$dQ1$$eT1 000041810 592__ $$a4.656$$b2015 000041810 593__ $$aPhysics and Astronomy (miscellaneous)$$c2015$$dQ1 000041810 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000041810 700__ $$0(orcid)0000-0002-3376-0327$$aMartín-Mayor, V. 000041810 700__ $$aParisi, G. 000041810 700__ $$0(orcid)0000-0001-8425-7345$$aPerez-Gaviro, S.$$uUniversidad de Zaragoza 000041810 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
