Transition to Synchrony in a Three-Dimensional Swarming Model with Helical Trajectories
Chunming Zheng, Ralf Toenjes, Arkady Pikovsky
We investigate the transition from incoherence to global collective motion in a three-dimensional swarming model of agents with helical trajectories, subject to noise and global co…
Coupled Moebius Maps as a Tool to Model Kuramoto Phase Synchronization
Chen Chris Gong, Ralf Toenjes, Arkady Pikovsky
We propose Moebius maps as a tool to model synchronization phenomena in coupled phase oscillators. Not only does the map provide fast computation of phase synchronization, it also…
Repulsively Coupled Kuramoto-Sakaguchi Phase Oscillators Ensemble Subject to Common Noise
Chen Chris Gong, Chunming Zheng, Ralf Toenjes +1
We consider the Kuramoto-Sakaguchi model of identical coupled phase oscillators with a common noisy forcing. While common noise always tends to synchronize the oscillators, a stron…
Spectral properties of fractional Fokker-Plank operator for the Lévy flight in a harmonic potential
Ralf Toenjes, Igor M. Sokolov, Eugene B. Postnikov
We present a detailed analysis of the eigenfunctions of the Fokker-Planck operator for the Lévy-Ornstein-Uhlenbeck process, their asymptotic behavior and recurrence relations, expl…
Non-spectral relaxation in one dimensional Ornstein-Uhlenbeck processes
R. Toenjes, I. M. Sokolov, E. B. Postnikov
The relaxation of a dissipative system to its equilibrium state often shows a multiexponential pattern with relaxation rates, which are typically considered to be independent of th…
Tuning the Clock: Uranium and Thorium Chronometers Applied to CS 31082-001
R. Toenjes, H. Schatz, K. -L. Kratz +4
We obtain age estimates for the progenitor(s) of the extremely metal-poor ([Fe/H = -2.9) halo star CS 31082-001, based on the recently reported first observation of a Uranium abund…
