We demonstrate both numerically and analytically that even with undirected layers, interlayer directionality alone reproduces superdiffusion and the prime regime. We further reveal a new phenomenon, the directionality-induced jamming, whereby directed interlayer links hinder diffusion, fragmenting the system into dynamically disconnected components and preventing convergence to the steady state of the diffusion process. Via an optimization process, we show that this new regime is attainable in both toy models and real-world topologies. These findings underscore the crucial role of interlayer link directionality in shaping the emergent behavior of multiplex systems, with potential implications for the design and control of such systems. 000171787 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E36-23R$$9info:eu-repo/grantAgreement/ES/MICIU/PID2023-149409NB-I00 000171787 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000171787 655_4 $$ainfo:eu-repo/semantics/other$$vinfo:eu-repo/semantics/acceptedVersion 000171787 700__ $$0(orcid)0000-0002-3800-5304$$aTejedor, Alejandro$$uUniversidad de Zaragoza 000171787 700__ $$aWang, Xiangrong 000171787 700__ $$0(orcid)0000-0002-0895-1893$$aMoreno, Yamir$$uUniversidad de Zaragoza 000171787 7102_ $$12004$$2398$$aUniversidad de Zaragoza$$bDpto.
