Amplitude-Defect Mediated Transition to Partial Incoherence -- From Experiment to Theory
Nicolas Thomé, Yukiteru Murakami, Yannick Schöhs +1
Phase-only models have contributed significantly to the understanding of synchronization; however, they do not account for dynamical scenarios where amplitude dynamics matter. This…
Origin of Frequency Clusters and Self-Organized Triplet Locking in the Kuramoto Model with Inertia
Yannick Schöhs, Nicolas Thomé, Katharina Krischer
We investigate the origin of frequency clusters - states where multiple groups of oscillators with distinct mean frequencies coexist. We use the Kuramoto model with inertia, where…
Synchronized Bimodal Amplitude Patterns in Heterogeneous Oscillatory Media -- Experiment and Theory
Nicolas Thomé, Yukiteru Murakami, Katharina Krischer
We study an intricate mechanism of pattern formation in globally coupled heterogeneous oscillatory media. In anodic electrochemical etching of silicon, the electrode surface splits…
Time delay as the origin of oscillations in anodic Si electrodissolution
Yukiteru Murakami, Katharina Krischer
Silicon is the most important semiconductor electrode with applications in photoelectrochemistry and sensor technology. Yet its electrochemistry exhibits many poorly understood phe…
Hierarchical Clustering in Mean-Field Coupled Stuart-Landau Oscillators
Nicolas Thomé, Matthias Wolfrum, Katharina Krischer
Clustered solutions in oscillator networks provide an important insight into how a system might diversify from a synchronous solution into spatiotemporal complex solutions. They ca…
Electrolyte effects on the alkaline hydrogen evolution reaction: a mean-field approach
Lucas B. T. de Kam, Thomas L. Maier, Katharina Krischer
This paper introduces the combination of an advanced double-layer model with electrochemical kinetics to explain electrolyte effects on the alkaline hydrogen evolution reaction. It…
