Here we introduce hydrodynamic spin lattices (HSLs) of \u2018walking\u2019 droplets as a class of active spin systems with particle\u2013wave coupling. HSLs reveal various non-equilibrium symmetry-breaking phenomena, including transitions from antiferromagnetic to ferromagnetic order that can be controlled by varying the lattice geometry and system rotation8. Theoretical predictions based on a generalized Kuramoto model derived from first principles rationalize our experimental observations, establishing HSLs as a versatile platform for exploring active phase oscillator dynamics. The tunability of HSLs suggests exciting directions for future research, from active spin\u2013wave dynamics to hydrodynamic analogue computation and droplet-based topological insulators.<\/p>\n\n\n\n<p>See paper here:  S\u00e1enz, Pucci, Goujon, Rosales, Dunkel &amp; Bush, Nature (2021) <a href=\"https:\/\/thales.mit.edu\/bush\/wp-content\/uploads\/2021\/08\/Saenz-HSL-2021.pdf\">pdf<\/a><\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":5,"featured_media":7068,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15,3,1],"tags":[],"class_list":["post-7029","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-hydrodynamic-quantum-analogues","category-pilot-wave-hydrodynamics","category-uncategorized","entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v16.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Hydrodynamic spin lattices - John W.
