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…
Large Mpemba-like effect in a gas of inelastic rough hard spheres
Aurora Torrente, Miguel A. López-Castaño, Antonio Lasanta +3
We report the emergence of a giant Mpemba effect in the uniformly heated gas of inelastic rough hard spheres: The initially hotter sample may cool sooner than the colder one, even…
