In this article, we present a combined experimental and numerical study exploring the dynamical role of unstable equilibrium solutions and their invariant manifolds in a weakly turbulent, electromagnetically driven, shallow fluid layer. Identifying instants when turbulent evolution slows down, we compute 31 unstable equilibria of a realistic two-dimensional model of the flow. We establish the dynamical relevance of these unstable equilibria by showing that they are closely visited by the turbulent flow. We also establish the dynamical relevance of unstable manifolds by verifying that they are shadowed by turbulent trajectories departing from the neighborhoods of unstable equilibria over large distances in state space.","lang":"eng"}],"date_published":"2018-08-13T00:00:00Z","publication_status":"published","issue":"2","month":"08","article_processing_charge":"No","date_updated":"2023-10-10T13:29:10Z","type":"journal_article","day":"13","quality_controlled":"1","title":"Unstable equilibria and invariant manifolds in quasi-two-dimensional Kolmogorov-like flow","status":"public","publisher":"American Physical Society","scopus_import":"1","oa":1,"oa_version":"Submitted Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2018-12-11T11:44:49Z"}
