Topological delocalisation of confined 3D active nematics
Louise C. Head, Pasquale Digregorio, Davide Marenduzzo +3
Defect lines in 3D active nematic systems are intriguing topological singularities whose out-of-equilibrium dynamics remain elusive in confined settings. Here, we numerically study…
Discontinuous transition in electrolyte flow through charge-patterned nanochannels
Tine Curk, Sergi G. Leyva, Ignacio Pagonabarraga
We investigate the flow of an electrolyte through a rigid nanochannel decorated with a surface charge pattern. Employing lattice Boltzmann and dissipative particle dynamics methods…
Bistability, oscillations and bidirectional motion of ensemble of hydrodynamically-coupled molecular motors
P. Malgaretti, I. Pagonabarraga, J. F. Joanny
We analyze the collective behavior of hydrodynamically coupled molecular motors. We show that the local fluxes induced by motors displacement can induce the experimentally observed…
Sedimentation of pairs of hydrodynamically interacting semiflexible filaments
Isaac Llopis, Ignacio Pagonabarraga, Marco Cosentino Lagomarsino +1
We describe the effect of hydrodynamic interactions in the sedimentation of a pair of inextensible semiflexible filaments under a uniform constant force at low Reynolds numbers. We…
A Lattice-Boltzmann model for suspensions of self-propelling colloidal particles
Sanoop Ramachandran, P. B. Sunil Kumar, I. Pagonabarraga
We present a Lattice-Boltzmann method for simulating self-propelling (active) colloidal particles in two-dimensions. Active particles with symmetric and asymmetric force distributi…
Lattice Boltzmann for Binary Fluids with Suspended Colloids
K. Stratford, R. Adhikari, I. Pagonabarraga +1
A new description of the binary fluid problem via the lattice Boltzmann method is presented which highlights the use of the moments in constructing two equilibrium distribution fun…
