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…
Direct Measurement of Lighthill's Energetic Efficiency of a Minimal Magnetic Microswimmer
Carles Calero, José García-Torres, Antonio Ortiz-Ambriz +3
The realization of artificial microscopic swimmers able to propel in viscous fluids is an emergent research field of fundamental interest and vast technological applications. For c…
Ice Rule and Emergent Frustration in Particle Ice and Beyond
Antonio Ortiz-Ambriz, Cristiano Nisoli, Charles Reichhardt +2
Geometric frustration and the ice rule are two concepts that are intimately connected and widespread across condensed matter. The first refers to the inability of a system to satis…
Magnetic assembly and annealing of colloidal lattices and superlattices
Pietro Tierno
The ability to assemble mesoscopic colloidal lattices above a surface is important for fundamental studies related with nucleation and crystallization, but also for a variety of te…
A Tuneable Magnetic Domain Wall Conduit Regulating Nanoparticle Diffusion
Pietro Tierno, Tom H. Johansen, Jose M. Sancho
We demonstrate a general and robust method to confine on a plane strongly diffusing submicrometer particles in water by using size tunable magnetic channels. These virtual conduits…
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…
