A Nonlinear Delay Model for Metabolic Oscillations in Yeast Cells
Max M. Chumley, Firas A. Khasawneh, Andreas Otto +1
We introduce two time-delay models of metabolic oscillations in yeast cells. Our model tests a hypothesis that the oscillations occur as multiple pathways share a limited resource…
Finite-element dynamic-matrix approach for propagating spin waves: Extension to mono- and multilayers of arbitrary spacing and thickness
Lukas Körber, Alexander Hempel, Andreas Otto +4
In our recent work [AIP Adv. 11, 095006], we presented an efficient numerical method to compute dispersions and spatial mode profiles of spin waves propagating in waveguides with t…
Finite-element dynamic-matrix approach for spin-wave dispersions in magnonic waveguides with arbitrary cross section
Lukas Körber, Gwendolyn Quasebarth, Andreas Otto +1
We present a numerical approach to efficiently calculate spin-wave dispersions and spatial mode profiles in magnetic waveguides of arbitrarily shaped cross section with any non-col…
The dynamics of a driven harmonic oscillator coupled to independent Ising spins in random fields
Paul Zech, Andreas Otto, Günter Radons
We aim at an understanding of the dynamical properties of a periodically driven damped harmonic oscillator coupled to a Random Field Ising Model (RFIM) at zero temperature, which i…
The dynamics of a driven harmonic oscillator coupled to pairwise interacting Ising spins in random fields
Paul Zech, Andreas Otto, Günter Radons
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 har…
Laminar Chaos in experiments and nonlinear delayed Langevin equations: A time series analysis toolbox for the detection of Laminar Chaos
David Müller-Bender, Andreas Otto, Günter Radons +2
Recently, it was shown that certain systems with large time-varying delay exhibit different types of chaos, which are related to two types of time-varying delay: conservative and d…
