Mobility-induced phase separation in a binary mixture of active Brownian particles
D. Jiménez-Flores, A. Rodríguez-Rivas, J. M. Romero-Enrique
In this paper, we report a Brownian dynamics simulation of the mobility-induced phase separation which occurs in a two-dimensional binary mixture of active soft Brownian particles,…
Diffusion of Tracer Particles in Early Growing Biofilms. A Computer Simulation Study
Fabian A. Garcia Daza, Alvaro Rodriguez-Rivas, Fernando Govantes +1
The diffusion of particles in complex media has gained significant interest due to its dual relevance: probing the viscoelastic properties of materials via microrheology and assess…
Relevance of the Computational Models of Bacterial Interactions in the simulation of Biofilm Growth
Gabriel Santos-Díaz, Álvaro Rodríguez-Rivas, Alejandro Cuetos
This study explores the application of elongated particle interaction models, traditionally used in liquid crystal phase research, in the context of early bacterial biofilm develop…
On a conjecture concerning the Fisher--Widom line and the line of vanishing excess isothermal compressibility in simple fluids
Ana M. Montero, Álvaro Rodríguez-Rivas, Santos B. Yuste +2
In the statistical mechanics approach to liquid-state theory, understanding the role of the intermolecular potential in determining thermodynamic and structural properties is cruci…
Diffusion and velocity correlations of the phase transitions in a system of macroscopic rolling spheres
F. Vega Reyes, A. Rodríguez-Rivas, J. F. González-Saavedra +1
We study an air-fluidized granular monolayer, composed of plastic spheres which roll on a metallic grid. The air current is adjusted so that the spheres never loose contact with th…
Chiral flow in a binary mixture of two-dimensional active disks
Miguel Ángel López-Castaño, Álvaro Rodríguez-Rivas, Francisco Vega Reyes
We study, experimentally, the dynamics of a binary mixture of air-fluidized disks. The disks are chiral since they incorporate a set of blades with constant tilt. Both species are…
Diffusive regimes in a two-dimensional chiral fluid
Francisco Vega Reyes, Miguel A. López-Castaño, Álvaro Rodríguez-Rivas
Diffusion is a fundamental aspect of transport processes in biological systems, and thus, in the development of life itself. And yet, the diffusive dynamics of active fluids with d…
Spin and velocity correlations in a confined two-dimensional fluid of disk-shaped active rotors
Miguel Ángel López-Castaño, Alejandro Márquez-Seco, Alicia Márquez-Seco +2
We study the velocity autocorrelations in an experimental configuration of confined two-dimensional active rotors (disks). We report persistent small scale oscillations in both rot…
Chirality transitions in a system of active flat spinners
Miguel A. López-Castaño, Alejandro Márquez Seco, Alicia Márquez Seco +2
We study in this work the 2D dynamics of an experimental system of disk-shaped rotors, fluidized by turbulent upflow. Contrary to previous knowledge, our experiments show the same…
The pseudo-two-dimensional dynamics in a system of macroscopic rolling spheres
M. A. López-Castaño, J. F. González-Saavedra, A. Rodríguez-Rivas +3
We study in this work the dynamics of a collection of identical hollow spheres (ping-pong balls) that rest on a horizontal metallic grid. Fluidization is achieved by means of a tur…
Zero-gravity thermal convection in granular gases
Álvaro Rodríguez-Rivas, Miguel A. López-Castaño, Francisco Vega Reyes
Previous experimental and theoretical evidence has shown that convective flow may appear in granular fluids if subjected to a thermal gradient and gravity (Rayleigh-Bénard-type con…
Structural properties of the Jagla fluid
Mariano López de Haro, Álvaro Rodríguez-Rivas, Santos B. Yuste +1
The structural properties of the Jagla fluid are studied by Monte Carlo (MC) simulations, numerical solutions of integral equation theories, and the (semi-analytical) rational-func…
Filling and wetting transitions on sinusoidal substrates: a mean-field study of the Landau-Ginzburg model
Alvaro Rodriguez-Rivas, Jose Antonio Galvan Moreno, Jose M. Romero-Enrique
We study the interfacial phenomenology of a fluid in contact with a microstructured substrate within the mean-field approximation. The sculpted substrate is a one-dimensional array…
Observation of a tricritical wedge filling transition in the 3D Ising model
A. Rodriguez-Rivas, J. M. Romero-Enrique, L. F. Rull +1
In this Letter we present evidences of the occurrence of a tricritical filling transition for an Ising model in a linear wedge. We perform Monte Carlo simulations in a double wedge…
