Competing orders for the colloidal kagome ice: the importance of in-trap motion of the particles
Anne Le Cunuder, Irénée Frérot, Antonio Ortiz-Ambriz +1
Artificial ice systems have been designed to replicate paradigmatic phenomena observed in frustrated spin systems. Here we present a detailed theoretical analysis based on Monte-Ca…
Ice Rule Fragility via Topological Charge Transfer in Artificial Colloidal Ice
Andras Libal, Don Yun Lee, Antonio Ortiz-Ambriz +4
Artificial particle ices are model systems of constrained, interacting particles. They have been introduced theoretically to study ice-manifolds emergent from frustration, along wi…
Mixed-order phase transition in a colloidal crystal
Ricard Alert, Pietro Tierno, Jaume Casademunt
Mixed-order phase transitions display a discontinuity in the order parameter like first-order transitions yet feature critical behavior like second-order transitions. Such transiti…
Synchronous versus asynchronous transport of a paramagnetic particle in a modulated ratchet potential
Arthur V. Straube, Pietro Tierno
We present a combined experimental and theoretical study describing the dynamical regimes displayed by a paramagnetic colloidal particle externally driven above a stripe-patterned…
Giant transversal particle diffusion in a longitudinal magnetic ratchet
Pietro Tierno, Peter Reimann, Tom H. Johansen +1
We study the transversal motion of paramagnetic particles on a uniaxial garnet film, exhibiting a longitudinal ratchet effect in the presence of an oscillating magnetic field. With…
