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…
The Concept of Spin Ice Graphs and a Field Theory for their Topological Monopoles and Charges
Cristiano Nisoli
Spin ices can now be fabricated in a variety of geometries which control their collective behavior and exotic properties. Therefore, their proper framework is graph theory. We rela…
Equilibrium Field Theory of Magnetic Monopoles in Degenerate Square Spin Ice: Correlations, Entropic Interactions, and Charge Screening Regimes
Cristiano Nisoli
We describe degenerate square spin as an ensemble of magnetic monopoles coupled via an emergent entropic field that subsumes the effect of the underlying spin vacuum. We compute th…
String Phase in an Artificial Spin Ice
Xiaoyu Zhang, Ayhan Duzgun, Yuyang Lao +13
One-dimensional strings of local excitations are a fascinating feature of the physical behavior of strongly correlated topological quantum matter. Here we study strings of local ex…
Qubit spin ice
Andrew D. King, Cristiano Nisoli, Edward D. Dahl +2
Artificial spin ices are frustrated spin systems that can be engineered, wherein fine tuning of geometry and topology has allowed the design and characterization of exotic emergent…
