Predicting First-Passage Dynamics in Disordered Systems Exactly: Application to Sparse Networks
Daniel Marris, Chittaranjan Hens, Subrata Ghosh +1
Quantifying how spatial disorder affects the movement of a diffusing particle or agent is fundamental to target search studies. When diffusion occurs on a network, that is on a hig…
Collective Foraging and Behavioural Syndromes in Ants: First-Passage Statistics with Heterogeneous Walkers on a Honeycomb Lattice
Daniel Marris, Pol Fernández-López, Frederic Bartumeus +1
Behavioral heterogeneities in animals, also known as syndromes, play a crucial role in understanding how natural populations flexibly adapt to environmental changes. In ant species…
Multi-target search in bounded and heterogeneous environments: a lattice random walk perspective
Luca Giuggioli, Seeralan Sarvaharman, Debraj Das +2
For more than a century lattice random walks have been employed ubiquitously, both as a theoretical laboratory to develop intuition about more complex stochastic processes and as a…
Persistent and anti-Persistent Motion in Bounded and Unbounded Space: Resolution of the First-Passage Problem
Daniel Marris, Luca Giuggioli
The presence of temporal correlations in random movement trajectories is a widespread phenomenon across biological, chemical and physical systems. The ubiquity of persistent and an…
