Interplay between scales in the nonlocal FKPP equation
G. G. Piva, E. H. Colombo, C. Anteneodo
We consider a generalization of the FKPP equation for the evolution of the spatial density of a single-species population where all the terms are nonlocal. That is, the spatial ext…
Random diffusivity scenarios behind anomalous non-Gaussian diffusion
M. A. F. dos Santos, E. H. Colombo, C. Anteneodo
The standard diffusive spreading, characterized by a Gaussian distribution with mean square displacement that grows linearly with time, can break down, for instance, under the pres…
Critical patch size reduction by heterogeneous diffusion
M. A. F. dos Santos, V. Dornelas, E. H. Colombo +1
Population survival depends on a large set of factors that includes environment structure. Due to landscape heterogeneity, species can occupy particular regions that provide the id…
Heat flux direction controlled by power-law oscillators under non-Gaussian fluctuations
E. H. Colombo, L. A. C. A. Defaveri, C. Anteneodo
Chains of particles coupled through anharmonic interactions and subject to non-Gaussian baths can exhibit paradoxical outcomes such as heat currents flowing from colder to hotter r…
Environment fluctuations on single species pattern formation
L. A. da Silva, E. H. Colombo, C. Anteneodo
System-environment interactions are intrinsically nonlinear and dependent on the interplay between many degrees of freedom. The complexity may be even more pronounced when one aims…
