Fluctuating growth rates link turnover and unevenness in species-rich communities
Emil Mallmin, Arne Traulsen, Silvia De Monte
The maintenance of diversity, the `commonness of rarity', and compositional turnover are ubiquitous features of species-rich communities. Through a minimal model, we consider how t…
Chaotic turnover of rare and abundant species in a strongly interacting model community
Emil Mallmin, Arne Traulsen, Silvia De Monte
The composition of ecological communities varies not only between different locations but also in time. Understanding the fundamental processes that drive species towards rarity or…
Large deviations of currents in diffusions with reflective boundaries
Emil Mallmin, Johan du Buisson, Hugo Touchette
We study the large deviations of current-type observables defined for Markov diffusion processes evolving in smooth bounded regions of with reflections at the bounda…
Inter-particle ratchet effect determines global current of heterogeneous particles diffusing in confinement
Emil Mallmin, Richard A. Blythe, Martin Evans
In a model of volume-excluding spheres in a -dimensional tube, we consider how differences between particles in their drift velocities, diffusivities, and sizes influence th…
A comparison of dynamical fluctuations of biased diffusion and run-and-tumble dynamics in one dimension
Emil Mallmin, Richard A Blythe, Martin R Evans
We compare the fluctuations in the velocity and in the fraction of time spent at a given position for minimal models of a passive and an active particle: an asymmetric random walke…
Exact spectral solution of two interacting run-and-tumble particles on a ring lattice
Emil Mallmin, Richard A Blythe, Martin R Evans
Exact solutions of interacting random walk models, such as 1D lattice gases, offer precise insight into the origin of nonequilibrium phenomena. Here, we study a model of run-and-tu…
