Hydrodynamic description of proliferating active matter
Nathan Silvano, Emilio Hernandez-Garcia, Cristóbal López +1
We develop a continuum theory for proliferating active matter starting from a microscopic stochastic model of self-propelled particles undergoing birth, death, and nonlocal competi…
Impact of fluctuations on particle systems described by Dean-Kawasaki-type equations
Nathan O. Silvano, Emilio Hernández-GarcÃa, Cristóbal López
We study the role of fluctuations in particle systems modeled by Dean-Kawasaki-type equations, which describe the evolution of particle densities in systems with Brownian motion. B…
The stochastic skeleton model for the Madden-Julian Oscillation with time-dependent observation-based forcing
Noémie Ehstand, Reik V. Donner, Cristóbal López +2
We analyze solutions to the stochastic skeleton model, a minimal nonlinear oscillator model for the Madden-Julian Oscillation (MJO). This model has been recognized for its ability…
Flow spatial structure determines pattern instabilities in nonlocal models of population dynamics
Nathan O. Silvano, João Valeriano, Emilio Hernández-GarcÃa +2
We investigate how environmental flows influence spatial pattern formation and population dynamics using two nonlocal models of population dynamics, which we couple to two differen…
Proliferating active disks with game dynamical interaction
Alejandro Almodóvar, Tobias Galla, Cristóbal López
We study a system of self-propelled, proliferating finite-size disks with game-theoretical interactions, where growth rates depend on local population composition. We analyze how t…
Spatial competition and repulsion: pattern formation and the role of movement
Cristóbal López, Eduardo H. Colombo, Emilio Hernández-GarcÃa +1
This chapter investigates some mechanisms behind pattern formation driven by competitive-only or repelling interactions, and explores how these patterns are influenced by different…
