Ordering of Binary Colloidal Crystals by Random Potentials
Andre S. Nunes, Sabareesh K. P. Velu, Iryna Kasianiuk +6
Structural defects are ubiquitous in condensed matter, and not always a nuisance. For example, they underlie phenomena such as Anderson localization and hyperuniformity, and they a…
Dynamical demixing of a binary mixture under sedimentation
A. S. Nunes, R. C. V. Coelho, V. C. Braz +2
We investigate the sedimentation dynamics of a binary mixture, the species of which differ by their Stokes coefficients but are identical otherwise. We analyze the sedimentation dy…
Field-driven dynamical demixing of binary mixtures
André S. Nunes, Akshat Gupta, Nuno A. M. Araújo +1
We consider mixtures of two species of spherical colloidal particles that differ in their hydrodynamic radii, but are otherwise identical, in the presence of an external field. Sin…
Demixing of active particles in the presence of external fields
Sunita Kumari, Andre S. Nunes, Nuno A. M. Araujo +1
Active systems are inherently out of equilibrium, as they collect energy from their surroundings and transform it into directed motion. A recent theoretical study suggests that bin…
Kinetic control of the coverage of oil droplets by DNA-functionalised colloids
Darshana Joshi, Dylan Bargteil, Alessio Caciagli +7
We report a study of reversible adsorption of DNA-coated colloids on complementary functionalized oil droplets. We show that it is possible to control the surface coverage of oil d…
Self-assembly of colloidal bands driven by a periodic external field
A. S. Nunes, N. A. M. Araujo, M. M. Telo da Gama
We study the formation of bands of colloidal particles driven by periodic external fields. Using Brownian dynamics, we determine the dependence of the band width on the strength of…
Evolution of Semilocal String Networks: I. Large-scale Properties
A. Achúcarro, A. Avgoustidis, A. M. M. Leite +4
We report on a detailed numerical study of the evolution of semilocal string networks, based on the largest and most accurate field theory simulations of these objects to date. We…
Analytic Models for the Evolution of Semilocal String Networks
A. S. Nunes, A. Avgoustidis, C. J. A. P. Martins +1
We revisit previously developed analytic models for defect evolution and adapt them appropriately for the study of semilocal string networks. We thus confirm the expectation (based…
