Optical trapping and critical Casimir forces
Agnese Callegari, Alessandro Magazzù, Andrea Gambassi +1
Critical Casimir forces emerge between objects, such as colloidal particles, whenever their surfaces spatially confine the fluctuations of the order parameter of a critical liquid…
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…
Clustering of Janus Particles in Optical Potential Driven by Hydrodynamic Fluxes
S. Masoumeh Mousavi, Sabareesh K. P. Velu, Agnese Callegari +2
Self-organisation is driven by the interactions between the individual components of a system mediated by the environment, and is one of the most important strategies used by many…
Controlling the dynamics of colloidal particles by critical Casimir forces
Alessandro Magazzù, Agnese Callegari, Juan Pablo Staforelli +3
Critical Casimir forces can play an important role for applications in nano-science and nanotechnology, owing to their piconewton strength, nanometric action range, fine tunability…
Active Matter Alters the Growth Dynamics of Coffee Rings
Tugba Andac, Pascal Weigmann, Sabareesh K. P. Velu +4
How particles are deposited at the edge of evaporating droplets, i.e. the {\em coffee ring} effect, plays a crucial role in phenomena as diverse as thin-film deposition, self-assem…
Repulsion-Sustained Supercurrent and Flux Quantization in Rings of Symmetric Hubbard Clusters
Agnese Callegari, Michele Cini, Enrico Perfetto +1
We test the response to a threading magnetic field of rings of 5-site -symmetric repulsive Hubbard clusters connected by weak intercell links; each 5-site unit has the topo…
