From dynamical systems with time-varying delay to circle maps and Koopman operators.
Müller D, Otto A, Radons G. Müller D, et al. Among authors: otto a. Phys Rev E. 2017 Jun;95(6-1):062214. doi: 10.1103/PhysRevE.95.062214. Epub 2017 Jun 16. Phys Rev E. 2017. PMID: 28709184
In this paper, we investigate the influence of the retarded access by a time-varying delay on the dynamics of delay systems. We show that there are two universality classes of delays, which lead to fundamental differences in dynamical quantities such as the Lyapunov spectr …

Laminar Chaos.
Müller D, Otto A, Radons G. Müller D, et al. Among authors: otto a. Phys Rev Lett. 2018 Feb 23;120(8):084102. doi: 10.1103/PhysRevLett.120.084102. Phys Rev Lett. 2018. PMID: 29543029
Laminar chaos in experiments and nonlinear delayed Langevin equations: A time series analysis toolbox for the detection of laminar chaos.
Müller-Bender D, Otto A, Radons G, Hart JD, Roy R. Müller-Bender D, et al. Among authors: otto a. Phys Rev E. 2020 Mar;101(3-1):032213. doi: 10.1103/PhysRevE.101.032213. Phys Rev E. 2020. PMID: 32289959
In contrast, the recently discovered low-dimensional laminar chaos is characterized by nearly constant laminar phases with periodic durations and a chaotic variation of the intensity from phase to phase. In this paper we extend our results from our preceding publication [H …

Dynamics of a driven harmonic oscillator coupled to pairwise interacting Ising spins in random fields.
Zech P, Otto A, Radons G. Zech P, et al. Among authors: otto a. Phys Rev E. 2021 Nov;104(5-1):054212. doi: 10.1103/PhysRevE.104.054212. Phys Rev E. 2021. PMID: 34942718
In general we are interested in dynamical systems coupled to complex hysteresis. Therefore as a first step we investigated recently the dynamics of a periodically driven damped harmonic oscillator coupled to independent Ising spins in a random field. Although …
