Here, we show how gauge theories can defy this wisdom\r\nby yielding constrained models with faster-than-diffusive dynamics. We first show how, upon integrating out\r\nthe gauge fields, one-dimensional U(1) lattice gauge theories are exactly mapped onto XX models with nonlocal\r\nconstraints. This class of kinetically constrained models interpolates between free theories and highly constrained\r\nlocal fermionic models. We find that energy transport is superdiffusive over a broad parameter regime. Even\r\nmore drastically, spin transport exhibits ballistic behavior, albeit with anomalous finite-volume properties as a\r\nconsequence of gauge invariance. Our findings are relevant to current efforts in quantum simulations of gauge theory dynamics and anomalous hydrodynamics in closed quantum many-body systems.","lang":"eng"}],"article_processing_charge":"No","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2509.08889"}],"publisher":"American Physical Society","ec_funded":1,"month":"09","project":[{"_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control","grant_number":"850899","call_identifier":"H2020"},{"call_identifier":"H2020","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","name":"IST-BRIDGE: International postdoctoral program","grant_number":"101034413"}],"date_updated":"2026-10-07T09:29:50Z","issue":"14","publication_status":"published","OA_place":"repository","status":"public","OA_type":"green","date_created":"2026-10-01T15:48:35Z","das_tickbox":"1","supplementarymaterial":"no","external_id":{"arxiv":["2509.08889"]},"quality_controlled":"1"}]
