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…
Dynamics and Clogging of colloidal monolayers magnetically driven through an heterogeneous landscape
Sergi Granados Leyva, Ralph Lukas Stoop, Pietro Tierno +1
We combine experiments and numerical simulations to investigate the emergence of clogging in a system of interacting paramagnetic colloidal particles driven against a disordered la…
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…
