Symmetric preferences, asymmetric outcomes: Tipping dynamics in an open-city segregation model
Fabio van Dissel, Tuan Minh Pham, Wout Merbis
Schelling's model of segregation demonstrates that even in the absence of social or governmental interventions, individuals with mild in-group preferences can self-organize into st…
Hyperscaling of spatial fluctuations constrains the development of urban populations
Wout Merbis, Fernando A. N. Santos, Jay Armas +2
Urban populations exhibit fractal organization and systematic scaling regularities, yet the scaling exponents reported across cities vary substantially, challenging existing theory…
Field theories and quantum methods for stochastic reaction-diffusion systems
Mauricio J. del Razo, Tommaso Lamma, Wout Merbis
Complex systems are composed of many particles or agents that move and interact with one another. The underlying mathematical framework to model many of these systems must incorpor…
Effective dimensional reduction of complex systems based on tensor networks
Wout Merbis, Madelon Geurts, Clélia de Mulatier +1
The exact treatment of Markovian models of complex systems requires knowledge of probability distributions exponentially large in the number of components . Mean-field approxima…
