Defect Dynamics in Artificial Colloidal Ice: Real-Time Observation, Manipulation and Logic Gate
Johannes Loehr, Antonio Ortiz-Ambriz, Pietro Tierno
We study the defect dynamics in a colloidal spin ice system realized by filling a square lattice of topographic double well islands with repulsively interacting magnetic colloids.…
Engineering of frustration in colloidal artificial ices realized on microfeatured grooved lattices
Antonio Ortiz-Ambriz, Pietro Tierno
Artificial spin ice systems, namely lattices of interacting single domain ferromagnetic islands, have been used to date as microscopic models of frustration induced by lattice topo…
Colloidal Microworms Propelling via a Cooperative Hydrodynamic Conveyor Belt
Fernando Martinez-Pedrero, Antonio Ortiz-Ambriz, Ignacio Pagonabarraga +1
We study propulsion arising from microscopic colloidal rotors dynamically assembled and driven in a viscous fluid upon application of an elliptically polarized rotating magnetic fi…
