Phase Separation in a system of Brownian inertial rotors
Lucio Mauro Carenza, Pasquale Digregorio, Massimiliano Semeraro +3
We uncover an emergent phase separation in a system of inertial dumbbells put into persistent rotation by a constant applied torque, breaking chiral symmetry, while interacting wit…
Active spin model for cell assemblies on 1D substrates
Harshal Potdar, Ignacio Pagonabarraga, Sudipto Muhuri
The experimental use of micropatterned quasi-1D substrates has emerged as an useful experimental tool to study the nature of cell-cell interactions and gain insight on collective b…
Segregation and cooperation in active colloidal binary mixtures
Laura Alvarez, Elena Sesé-Sansa, Demian Levis +2
The complex interactions underlying collective motion in biological systems give rise to emergent behaviours such as flocking, sorting, and cooperative transport. These dynamics of…
Phase separation in a chiral active fluid of inertial self-spinning disks
Pasquale Digregorio, Ignacio Pagonabarraga, Francisco Vega Reyes
We show that systematic particle rotations in a fluid composed of disk-shaped spinners can spontaneously lead to phase separation. The phenomenon arises out of a homogeneous and hy…
Activity leads to topological phase transition in 2D populations of heterogeneous oscillators
Ylann Rouzaire, Parisa Rahmani, Ignacio Pagonabarraga +2
Populations of heterogeneous, noisy oscillators on a two-dimensional lattice display short-range order. Here, we show that if the oscillators are allowed to actively move in space,…
Non-Reciprocal Interactions Reshape Topological Defect Annihilation
Ylann Rouzaire, Daniel JG Pearce, Ignacio Pagonabarraga +1
We show how non-reciprocal ferromagnetic interactions between neighbouring planar spins in two dimensions, affect the behaviour of topological defects. Non-reciprocity is introduce…
