Inference of Hamiltonian and Lie-Poisson structures from vector field samples
Jason E. Frank, Georg A. Gottwald
We present a method for the data-driven inference of Hamiltonian and Lie-Poisson dynamical systems from vector-field samples, in which the Hamiltonian and the underlying Poisson te…
Intrinsic Neuro-Synaptic Spiking Dynamics and Resonance in Memristive Networks
Yinhao Xu, Georg A. Gottwald, Zdenka Kuncic
Self-organizing memristive networks are physical circuits that dynamically reconfigure their circuitry in response to external input signals. Their adaptive behavior arises from in…
An improved noise model for representing westerly wind bursts in the recharge oscillator model of ENSO
Georg A. Gottwald, Eli Tziperman, Alexey Fedorov
Westerly wind bursts (WWBs) have long been known to have a major impact on the development of El Niño events. In particular, they amplify these events, with stronger events associa…
Mean-field approach to finite-size fluctuations in the Kuramoto-Sakaguchi model
Oleh E. Omel'chenko, Georg A. Gottwald
We develop an ab initio approach to describe the statistical behavior of finite-size fluctuations in the deterministic Kuramoto-Sakaguchi model. We obtain explicit expressions for…
Finite-size induced random switching of chimeras in a deterministic two-population Kuramoto-Sakaguchi model
Henry Irvine, Georg A. Gottwald
The two-population Kuramoto-Sakaguchi model for interacting populations of phase oscillators exhibits chimera states whereby one population is synchronised, and the other is desync…
Choosing observables that capture critical slowing down before tipping points: A Fokker-Planck operator approach
Johannes Lohmann, Georg A. Gottwald
Tipping points (TP) are abrupt transitions between metastable states in complex systems, most often described by a bifurcation or crisis of a multistable system induced by a slowly…
