Synchronisation of time--delay systems
Martin J. Bünner, Wolfram Just
We present the linear-stability analysis of synchronised states in coupled time-delay systems. There exists a synchronisation threshold, for which we derive upper bounds, which doe…
Delayed feedback control of periodic orbits in autonomous systems
Wolfram Just, Dirk Reckwerth, Johannes Möckel +2
For controlling periodic orbits with delayed feedback methods the periodicity has to be known a priori. We propose a simple scheme, how to detect the period of orbits from properti…
Analytical Approach for Piecewise Linear Coupled Map Lattices
Wolfram Just
A simple construction is presented, which generalises piecewise linear one-dimensional Markov maps to an arbitrary number of dimensions. The corresponding coupled map lattice, know…
Stochastic Resonance in Chaotic Spin-Wave Dynamics
Ekkehard Reibold, Wolfram Just, Hartmut Benner
We report the first experimental observation of noise-free stochastic resonance by utilizing the intrinsic chaotic dynamics of the system. To this end we have investigated the effe…
On the Collective Motion in Globally Coupled Chaotic Systems
Wolfram Just
A mean-field formulation is used to investigate the bifurcation diagram for globally coupled tent maps by means of an analytical approach. It is shown that the period doubling sequ…
On the Mechanism of Time--Delayed Feedback Control
Wolfram Just, Thomas Bernard, Matthias Ostheimer +2
The Pyragas method for controlling chaos is investigated in detail from the experimental as well as theoretical point of view. We show by an analytical stability analysis that the…
