Partial vision leads to an unexpected emergent collective behavior in active aligning particles
Raúl Molina-Prados Lallena, José MartÃn-Roca, Chantal Valeriani
The paper extends the Vicsek model by giving particles limited, directional vision cones, showing how anisotropic and non‑reciprocal perception changes collective motion, leading t…
Tunable mesoscopic numerical model for bacterial biofilms
J. Martin-Roca, B. Wu-Zhang, J. Oller +2
We present a tunable mesoscale model to provide a basis for future rheological calculations of of bacterial biofilms, explicitly incorporating reversible crosslinking within the ex…
How Phase Coexistence affects the mechanical properties of heterogeneous 2D suspensions
Raul Molina-Prados Lallena, Jose Martin-Roca, Kristian Thijssen +3
Although numerical simulations of rheological measurements typically focus on homogeneous systems, heterogeneity can profoundly impact material properties. We report on the rheolog…
Simulating active agents under confinement with Dissipative Particles (hydro)Dynamics
C. Miguel Barriuso G., Jose Martin-Roca, Valentino Bianco +2
We study active agents embedded in bulk or in confinement explicitly considering hydrodynamics and simulating the swimmers via an implementation inspired by the squirmer model. We…
Numerical methods for unraveling inter-particle potentials in colloidal suspensions: A comparative study for two-dimensional suspensions
Clare R. Rees-Zimmerman, José MartÃn-Roca, David Evans +3
We compare three model-free numerical methods for inverting structural data to obtain interaction potentials, namely iterative Boltzmann inversion (IBI), test-particle insertion (T…
Colloidal Model for Investigating Optimal Efficiency in Weakly Coupled Ratchet Motors
José MartÃn-Roca, Laura Izquierdo-SolÃs, Fernando MartÃnez-Pedrero +3
We investigate the transport of superparamagnetic colloidal particles along self-assembled tracks using a periodically applied magnetic field as a model for ratchet-like mechanisms…
