Synchronization in an evolving network
In this work we study the dynamics of Kuramoto oscillators on a
stochastically evolving network whose evolution is governed by the phases of
the individual oscillators and degree distribution. Synchronization is achieved
after a threshold connection density is reached. This cumulative effect of
topology and dynamics has many real-world implications, where synchronization
in a system emerges as a collective property of its components in a
self-organizing manner. The synchronous state remains stable as long as the
connection density remains above the threshold value, with additional links
providing resilience against network fluctuations.Comment: 4 pages, 4 figure
Jamming in a lattice model of stochastically interacting agents with a field of view
We study the collective dynamics of a lattice model of stochastically
interacting agents with a weighted field of vision. We assume that agents
preferentially interact with neighbours, depending on their relative location,
through velocity alignments and the additional constraint of exclusion. Unlike
in previous models of flocking, here the stochasticity arises intrinsically
from the interactions between agents, and its strength is dependent on the
local density of agents. We find that this system yields a first-order jamming
transition as a consequence of these interactions, even at a very low density.
Furthermore, the critical jamming density is found to strongly depend on the
nature of the field of view.Comment: 5 pages, 3 figures + 3 pages supplementary materia
