Multiple temperatures and melting of a colloidal active crystal
Helena Massana-Cid, Claudio Maggi, Nicoletta Gnan +2
Thermal fluctuations constantly and evenly excite all vibrational modes in an equilibrium crystal. As the temperature rises, these fluctuations promote the formation of defects and…
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…
Edge states at the boundary between topologically equivalent lattices
Helena Massana-Cid, Adrian Ernst, Daniel de las Heras +9
Edge currents of paramagnetic colloidal particles propagate at the edge between two topologically equivalent magnetic lattices of different lattice constant when the system is driv…
Orientational Dynamics of Fluctuating Dipolar Particles Assembled in a Mesoscopic Colloidal Ribbon
Helena Massana-Cid, Fernando Martinez-Pedrero, Andrejs Cebers +1
We combine experiments and theory to investigate the dynamics and orientational fluctuations of ferromagnetic microellipsoids that form a ribbon-like structure due to attractive di…
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…
