Extreme events and power-law distributions from nonlinear quantum dissipation
Power-law probability distributions are widely used to model extreme statistical events in complex systems, with applications to a vast array of natural phenomena ranging from earthquakes to stock market crashes to pandemics. We ... Read More >

Never Mind The No-Ops: Faster and Less Volatile Simulation Modelling of Co-Evolu ...
Issues in co-evolutionary population dynamics have long been studied via computationally intensive simulations of minimally simple agent-based models, known as Evolutionary Spatial Cyclic Games (ESCGs), involving multiple intera ... Read More >

Dynamical stability of evolutionarily stable strategy in asymmetric games
Evolutionarily stable strategy (ESS) is the defining concept of evolutionary game theory. It has a fairly unanimously accepted definition for the case of symmetric games which are played in a homogeneous population where all ind ... Read More >

Why collective behaviours self-organise to criticality: A primer on information- ...
Collective behaviours are frequently observed to self-organise to criticality. Existing proposals to explain these phenomena, such as Self-organised Criticality (SOC), are fragmented across disciplines and only partially answer ... Read More >

Biological arrow of time: Emergence of tangled information hierarchies and self- ...
We study open-ended evolution by focusing on computational and information-processing dynamics underlying major evolutionary transitions. In doing so, we consider biological organisms as hierarchical dynamical systems that gener ... Read More >

Expected and unexpected routes to synchronization in a system of swarmalators
Systems of oscillators whose internal phases and spatial dynamics are coupled, swarmalators, present diverse collective behaviors which in some cases lead to explosive synchronization in a finite population as a function of the ... Read More >

How Combined Pairwise and Higher-Order Interactions Shape Transient Dynamics
Understanding how species interactions shape biodiversity is a core challenge in ecology. While much focus has been on long-term stability, there is rising interest in transient dynamics-the short-lived periods when ecosystems r ... Read More >

Bifurcations in the Kuramoto model with external forcing and higher-order intera ...
Synchronization is an important phenomenon in a wide variety of systems comprising interacting oscillatory units, whether natural (like neurons, biochemical reactions, cardiac cells) or artificial (like metronomes, power grids, ... Read More >

The forced one-dimensional swarmalator model
We study a simple model of swarmalators subject to periodic forcing and confined to move around a one-dimensional ring. This is a toy model for physical systems with a mix of sync, swarming, and forcing such as colloidal micromo ... Read More >

Gaussian Process Phase Interpolation for estimating the asymptotic phase of a li ...
Rhythmic activity commonly observed in biological systems, occurring from the cellular level to the organismic level, is typically modeled as limit cycle oscillators. The phase reduction theory serves as a useful analytical fram ... Read More >
