Phase behaviour and dynamical features of a two-dimensional binary mixture of active/passive spherical particles
Diego Rogel Rodriguez, Francisco Alarcon, Raul Martinez +2
In this work we have characterized the phase behaviour and the dynamics of bidimensional mixtures of active and passive Brownian particles. We have evaluated state diagrams at seve…
Rheology of Pseudomonas fluorescens biofilms: from experiments to predictive DPD mesoscopic modelling
Jose Mart. n-Roca, Valentino Bianco, Francisco Alarcon +6
Bacterial biofilms mechanically behave as viscoelastic media consisting of micron-sized bacteria crosslinked to a selfproduced network of extracellular polymeric substances (EPS) e…
Rheology of Pseudomonas fluorescens biofilms: from experiments to DPD mesoscopic modelling
Jose Martin Roca, Valentino Bianco, Francisco Alarcon +6
The presence of bacterial biofilms in clinical and industrial settings is a major issue worldwide. A biofilm is a viscoelastic matrix, composed of bacteria producing a network of E…
Intrinsic structure perspective for MIPS interfaces in two dimensional systems of Active Brownian Particles
Enrique Chacon, Francisco Alarcon, Jorge Ramirez +2
Suspensions of Active Brownian Particles (ABP) undergo motility induced phase separation (MIPS) over a wide range of mean density and activity strength [1], even in the absence of…
Self-assembly of active amphiphilic Janus particles
S. A. Mallory, F. Alarcon, A. Cacciuto +1
In this article, we study the phenomenology of a two dimensional dilute suspension of active amphiphilic Janus particles. We analyze how the morphology of the aggregates emerging f…
In-silico modeling of early-stage biofilm formation
Pin Nie, Francisco Alarcon Oseguera, Ivan Lopez-Montero +3
Several bacteria and bacteria strands form biofilms in different environmental conditions, e.g. pH, temperature, nutrients, etc. Biofilm growth, therefore, is an extremely robust p…
Self-adaptation of Pseudomonas fluorescens biofilms to hydrodynamic stress
Josue J. Perez, Francisco Alarcon Oseguera, Ajay K. Monnappa +9
In some conditions, bacteria self-organise into biofilms, supracellular structures made of a self-produced embedding matrix, mainly composed on polysaccharides, DNA, proteins and l…
Characterization of MIPS in a suspension of repulsive Active Brownian Particles through dynamical features
Jose Martin, Raul Martinez, Lachlan C. Alexander +5
The two-dimensional Active Brownian Particles system is meant to be composed of hard disks, that show excluded volume interactions, usually simulated via molecular dynamics using p…
Trapping flocking particles with asymmetric obstacles
Raul Martinez, Francisco Alarcon, Juan Luis Aragones +1
Asymmetric obstacles can be exploited to direct the motion and induce sorting of run-and-tumbling particles. In this work, we show that flocking particles which follow the Vicsek m…
Collective behavior of Vicsek particles without and with obstacles
Raul Martinez, Francisco Alarcon, Diego Rogel Rodriguez +2
In our work we have studied a two-dimensional suspension of finite-size Vicsek hard-disks, whose time evolution follows an event-driven dynamics between subsequent time steps. Havi…
Orientational order and morphology of clusters of self-assembled Janus swimmers
Francisco Alarcon, Eloy Navarro-Argemí, Chantal Valeriani +1
Due to the combined effect of anisotropic interactions and activity, Janus swimmers are capable to self-assemble in a wide variety of structures, many more than their equilibrium c…
Morphology of clusters of attractive dry and wet self-propelled spherical particle suspensions
Francisco Alarcón, Chantal Valeriani, Ignacio Pagonabarraga
In order to asses the effect of hydrodynamics in the assembly of active attractive spheres, we simulate a semi-dilute suspension of attractive self-propelled spherical particles in…
