Nonlinearity of local dynamics promotes multi-chimeras
Iryna Omelchenko, Anna Zakharova, Philipp Hoevel +2
Chimera states are complex spatio-temporal patterns in which domains of synchronous and asynchronous dynamics coexist in coupled systems of oscillators. We examine how the characte…
Front and Turing patterns induced by Mexican-hat-like nonlocal feedback
Julien Siebert, Eckehard Schöll
We consider the effects of a Mexican-hat-shaped nonlocal spatial coupling, i.e., symmetric long-range inhibition superimposed with short-range excitation, upon front propagation in…
Control of chemical wave propagation
Jakob Löber, Rhoslyn Coles, Julien Siebert +2
Using the Schlögl model as a paradigmatic example of a bistable reaction-diffusion system, we discuss some physically feasible options of open and closed loop spatio-temporal contr…
Dynamics of reaction-diffusion patterns controlled by asymmetric nonlocal coupling as limiting case of differential advection
Julien Siebert, Sergio Alonso, Markus Bär +1
A one-component bistable reaction-diffusion system with asymmetric nonlocal coup ling is derived as limiting case of a two-component activator-inhibitor reaction -diffusion model w…
Statistical mechanics of the self-gravitating gases
Julien Siebert
The self-gravitating systems are formed by particles interacting through gravity. They describe structure formation in the universe. As a consequence of the long range interaction…
The Self-Gravitating Gas in the Presence of Dark Energy: Monte-Carlo Simulations and Stability Analysis
H. J. de Vega, J. A. Siebert
The self-gravitating gas in the presence of a positive cosmological constant Lambda is studied in thermal equilibrium by Monte Carlo simulations and by the mean field approach. We…
