Single-file dynamics of colloids in circular channels: time scales, scaling laws and their universality
Alejandro Villada-Balbuena, Antonio Ortiz-Ambriz, Pavel Castro-Villarreal +3
In colloidal systems, Brownian motion emerges from the massive separation of time and length scales associated to characteristic dynamics of the solute and solvent constituents. Th…
Topological Boundary Constraints in Artificial Colloidal Ice
Carolina Rodríguez-Gallo, Antonio Ortiz-Ambriz, Pietro Tierno
The effect of boundaries and how these can be used to influence the bulk behaviour in geometrically frustrated systems are both long-standing puzzles, often relegated to secondary…
Dynamical modes of sheared confined microscale matter
Sascha Gerloff, Antonio Ortiz-Ambriz, Pietro Tierno +1
Based on (overdamped) Stokesian dynamics simulations and video microscopy experiments, we study the non equilibrium dynamics of a sheared colloidal cluster, which is confined to a…
Propulsion and energetics of a minimal magnetic microswimmer
Carles Calero, José García-Torres, Antonio Ortiz-Ambriz +3
In this manuscript we describe the realization of a minimal hybrid microswimmer, composed of a ferromagnetic nanorod and a paramagnetic microsphere. The unbounded pair is propelled…
Topology Restricts Quasidegeneracy in Sheared Square Colloidal Ice
Erdal C. Oğuz, Antonio Ortiz-Ambriz, Hadas Shem-Tov +3
Recovery of ground-state degeneracy in two-dimensional square ice is a significant challenge in the field of geometric frustration with far-reaching fundamental implications, such…
Emergent colloidal edge currents generated via exchange dynamics in a broken dimer state
Helena Massana-Cid, Antonio Ortiz-Ambriz, Andrej Vilfan +1
Controlling the flow of matter down to micrometer-scale confinement is of central importance in materials and environmental sciences, with direct applications in nano-microfluidics…
