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.…

Taming active turbulence with patterned soft interfaces

Pau Guillamat, Jordi Ignés-Mullol, Francesc Sagués

Active matter embraces systems that self-organize at different length and time scales, often exhibiting turbulent flows. Here, we use a quasi-two-dimensional nematically ordered la…

Bidirectional particle transport and size selective sorting of Brownian particles in a flashing spatially periodic energy landscape

Fernando Martinez-Pedrero, Helena Massana-Cid, Till Ziegler +3

We demonstrate a size sensitive experimental scheme which enables bidirectional transport and fractionation of paramagnetic colloids in a fluid medium. It is shown that two types o…

Formation of metastable phases by spinodal decomposition

Ricard Alert, Pietro Tierno, Jaume Casademunt

Metastable phases may be spontaneously formed from other metastable phases through nucleation. Here we demonstrate the spontaneous formation of a metastable phase from an unstable…

Geometric Frustration of Colloidal Dimers on a Honeycomb Magnetic Lattice

Pietro Tierno

We study the phase behaviour and the collective dynamics of interacting paramagnetic colloids assembled above a honeycomb lattice of triangular shaped magnetic minima. A frustrated…

Transport and selective chaining of bidisperse particles in a travelling wave potential

Pietro Tierno, Arthur V. Straube

We combine experiments, theory and numerical simulation to investigate the dynamics of a binary suspension of paramagnetic colloidal particles dispersed in water and transported ab…

Orientational dynamics of colloidal ribbons self-assembled from microscopic magnetic ellipsoids

Fernando Martinez-Pedrero, Andrejs Cebers, Pietro Tierno

We combine experiments and theory to investigate the orientational dynamics of dipolar ellipsoids, which self-assemble into elongated ribbon-like structures due to the presence in…

Enhanced diffusion and anomalous transport of magnetic colloids driven above a two-state flashing potential

Pietro Tierno, M. Reza Shaebani

We combine experiment and theory to investigate the diffusive and subdiffusive dynamics of paramagnetic colloids driven above a two-state flashing potential. The magnetic potential…

Large Slowdown of Water Dynamics at Stacked Phospholipid Membranes for Increasing Hydration Level: All-Atoms Molecular Dynamics

Carles Calero, H. Eugene Stanley, Giancarlo Franzese

Water hydrating phospholipid membranes determine their stability and function, as well as their interaction with other molecules. In this article we study, using all-atom molecular…

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…

Functional colloidal micro-sieves assembled and guided above a channel-free magnetic striped film

Fernando Martinez-Pedrero, Arthur V. Straube, Tom H. Johansen +1

Colloidal inclusions in lab-on-a-chip devices can be used to perform analytic operations in a non-invasive fashion. We demonstrate here a novel approach to realize fast and reversi…

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…

Magnetic Propulsion of Self-Assembled Colloidal Carpets: Efficient Cargo Transport via a Conveyor-Belt Effect

Fernando Martinez-Pedrero, Pietro Tierno

We demonstrate a general method to assemble and propel highly maneuverable colloidal carpets which can be steered via remote control in any direction of the plane. These colloidal…
