Emergent charge crystallization and frustration in a particle anti-spin Ice
Renaud Baillou, Matthew Terkel, Cristiano Nisoli +1
Artificial spin ices have transcended their origins in frustrated rare-earth pyrochlores to become a versatile platform for engineering exotic states of matter. Across diverse impl…
Emergent dimer-model topological order and quasi-particle excitations in liquid crystals: combinatorial vortex lattices
Cuiling Meng, Jin-Sheng Wu, Žiga Kos +3
Liquid crystals have proven to provide a versatile experimental and theoretical platform for studying topological objects such as vortices, skyrmions, and hopfions. In parallel, in…
Ice Rule Breakdown and frustrated antiferrotoroidicity in an artificial colloidal Cairo ice
Carolina Rodríguez-Gallo, Antonio Ortiz-Ambriz, Cristiano Nisoli +1
We combine experiments and numerical simulations to investigate the low energy states and the emergence of topological defects in an artificial colloidal ice in the Cairo geometry.…
Emergent Disorder and Mechanical Memory in Periodic Metamaterials
Chaviva Sirote-Katz, Dor Shohat, Carl Merrigan +3
Ordered mechanical systems typically have one or only a few stable rest configurations, and hence are not considered useful for encoding memory. Multistable and history-dependent r…
Putting a spin on metamaterials: Mechanical incompatibility as magnetic frustration
Ben Pisanty, Erdal C. Oguz, Cristiano Nisoli +1
Mechanical metamaterials present a promising platform for seemingly impossible mechanics. They often require incompatibility of their elementary building blocks, yet a comprehensiv…
Topologically Protected Steady Cycles in an Ice-Like Mechanical Metamaterial
Carl Merrigan, Cristiano Nisoli, Yair Shokef
Competing ground states may lead to topologically constrained excitations such as domain walls or quasiparticles, which govern metastable states and their dynamics. Domain walls an…
