Our tracers diffuse anomalously over many decades in time, before reaching a diffusive steady state with an effective diffusion constant Deff, which depends on the obstacle diffusivity and density. The scaling of Deff, above and below a critical regime, is characterized by two independent critical parameters: the conductivity exponent µ, also found in models with frozen obstacles, and an exponent ¿, which quantifies the effect of obstacle diffusivity. 000151694 536__ $$9info:eu-repo/grantAgreement/ES/MICIU AEI/PID2022-136374NB-C21 000151694 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000151694 590__ $$a2.1$$b2024 000151694 592__ $$a0.659$$b2024 000151694 591__ $$aPHYSICS, MULTIDISCIPLINARY$$b49 / 114 = 0.43$$c2024$$dQ2$$eT2 000151694 593__ $$aMathematical Physics$$c2024$$dQ2 000151694 591__ $$aPHYSICS, MATHEMATICAL$$b17 / 61 = 0.279$$c2024$$dQ2$$eT1 000151694 593__ $$aModeling and Simulation$$c2024$$dQ2 000151694 593__ $$aStatistics and Probability$$c2024$$dQ2 000151694 593__ $$aStatistical and Nonlinear Physics$$c2024$$dQ2 000151694 593__ $$aPhysics and Astronomy (miscellaneous)$$c2024$$dQ2 000151694 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/submittedVersion 000151694 700__ $$aHuber, Greg 000151694 700__ $$0(orcid)0000-0001-7276-2942$$aYllanes, David 000151694 773__ $$g57, 44 (2024), 445207 [12 pp.]$$pJournal of Physics A-Mathematical and Theoretical$$tJournal of Physics A-Mathematical and Theoretical$$x1751-8113 000151694 8564_ $$s714648$$uhttps://zaguan.unizar.es/record/151694/files/texto_completo.pdf$$yPreprint 000151694 8564_ $$s1725788$$uhttps://zaguan.unizar.es/record/151694/files/texto_completo.jpg?subformat=icon$$xicon$$yPreprint 000151694 909CO $$ooai:zaguan.unizar.es:151694$$particulos$$pdriver 000151694 951__ $$a2025-10-17-14:27:01 000151694 980__ $$aARTICLE
