A toy model for brain criticality: self-organized excitation/inhibition ratio and the role of network clustering
Lorenz Baumgarten, Stefan Bornholdt
The critical brain hypothesis receives increasing support from recent experimental results. It postulates that the brain is at a critical point between an ordered and a chaotic reg…
A q-spin Potts model of markets: Gain-loss asymmetry in stock indices as an emergent phenomenon
Stefan Bornholdt
Spin models of markets inspired by physics models of magnetism, as the Ising model, allow for the study of the collective dynamics of interacting agents in a market. The number of…
Universal computation using localized limit-cycle attractors in neural networks
Lorenz Baumgarten, Stefan Bornholdt
Neural networks are dynamical systems that compute with their dynamics. One example is the Hopfield model, forming an associative memory which stores patterns as global attractors…
Self-organized criticality in neural networks from activity-based rewiring
Stefan Landmann, Lorenz Baumgarten, Stefan Bornholdt
Neural systems process information in a dynamical regime between silence and chaotic dynamics. This has lead to the criticality hypothesis which suggests that neural systems reach…
Epidemics with asymptomatic transmission: Sub-critical phase from recursive contact tracing
Lorenz Baumgarten, Stefan Bornholdt
The challenges presented by the COVID-19 epidemic have created a renewed interest in the development of new methods to combat infectious diseases. A prominent property of the SARS-…
Repulsion in controversial debate drives public opinion into fifty-fifty stalemate
Sebastian M. Krause, Fritz Weyhausen-Brinkmann, Stefan Bornholdt
Opinion formation is a process with strong implications for public policy. In controversial debates with large consequences, the public opinion is often trapped in a fifty-fifty st…
