Metastability induced by non-reciprocal adaptive couplings in Kuramoto models
Sayantan Nag Chowdhury, Hildegard Meyer-Ortmanns
Non-reciprocal couplings are frequently found in systems out-of-equilibrium such as neuronal networks. We consider generalized Kuramoto models with non-reciprocal adaptive coupling…
Topologically protected edge oscillations in nonlinear dynamical units
Sayantan Nag Chowdhury, Hildegard Meyer-Ortmanns
Many examples from quantum and classical physics are known where topological protection is responsible for the robustness of the dynamics. Less explored is the role of topological…
Rare desynchronization events in power grids: On data implementation and dimensional reductions
Tim Ritmeester, Hildegard Meyer-Ortmanns
We discuss the frequency of desynchronization events in power grids for realistic data input. We focus on the role of time correlations in the fluctuating power production and prop…
Belief propagation for supply networks: Efficient clustering of their factor graphs
Tim Ritmeester, Hildegard Meyer-Ortmanns
We consider belief propagation (BP) as an efficient and scalable tool for state estimation and optimization problems in supply networks such as power grids. BP algorithms make use…
Heteroclinic units acting as pacemakers: Entrained dynamics for cognitive processes
Bhumika Thakur, Hildegard Meyer-Ortmanns
Heteroclinic dynamics is a suitable framework for describing transient and reproducible dynamics such as cognitive processes in the brain. We demonstrate how heteroclinic units can…
The cavity method for minority games between arbitrageurs on financial markets
Tim Ritmeester, Hildegard Meyer-Ortmanns
We use the cavity method from statistical physics for analyzing the transient and stationary dynamics of a minority game that is played by agents performing market arbitrage. On th…
