Parameter degeneracy in the vertex model for tissues
Paulo C. Godolphim, Leonardo G. Brunnet, Rodrigo Soto
The vertex model with homogeneous cell properties is known to exhibit a parameter degeneracy in which the system's dynamics is independent of the target area. Here, we show, for th…

Hydrodynamic Equations for Active Brownian Particles in the High Persistence Regime
Martín Pinto-Goldberg, Rodrigo Soto
In the high persistence regime of non-inertial active Brownian particles (ABP), polarization becomes a relevant dynamical field. Based on a recently proposed kinetic description fo…

Two-field theory for phase coexistence of active Brownian particles
Pablo Perez-Bastías, Rodrigo Soto
Active Brownian particles (ABPs) serve as a minimal model of active matter systems. When ABPs are sufficiently persistent, they undergo a liquid-gas phase separation and, in the pr…
