Noise-Induced Schooling of Fish
Jitesh Jhawar, Richard G. Morris, U. R. Amith-Kumar +3
We report on the dynamics of collective alignment in groups of the cichlid fish, Etroplus suratensis. Focusing on small-to-intermediate sized groups (), we demonstrate th…
Spectral Theory of Sparse Non-Hermitian Random Matrices
Fernando Lucas Metz, Izaak Neri, Tim Rogers
Sparse non-Hermitian random matrices arise in the study of disordered physical systems with asymmetric local interactions, and have applications ranging from neural networks to eco…
Heterogeneous micro-structure of percolation in sparse networks
Reimer Kuehn, Tim Rogers
We examine the heterogeneous responses of individual nodes in sparse networks to the random removal of a fraction of edges. Using the message-passing formulation of percolation, we…
Growth-induced breaking and unbreaking of ergodicity in fully-connected spin systems
Richard G. Morris, Tim Rogers
Two canonical models of statistical mechanics, the fully-connected voter and Glauber-Ising models, are modified to incorporate growth via the addition or replication of spins. The…
Stochastic dynamics on slow manifolds
George W A Constable, Alan J McKane, Tim Rogers
The theory of slow manifolds is an important tool in the study of deterministic dynamical systems, giving a practical method by which to reduce the number of relevant degrees of fr…
Voter models with conserved dynamics
Fabio Caccioli, Luca Dall'Asta, Tobias Galla +1
We propose a modified voter model with locally conserved magnetization and investigate its phase ordering dynamics in two dimensions in numerical simulations. Imposing a local cons…
