Phase oscillator networks with multiple and state-dependent delays: A framework for exploring white matter plasticity in neurodynamics
Grace Jolly, Rachel Nicks, Stefan Ruschel +2
Network science is increasingly focused on how node dynamics influence emergent phenomena such as oscillations, waves, chimeras, and turbulence. In oscillatory systems modeled by n…
Adaptive conduction delays and phase locking in spiking Haken Lighthouse networks
Stephen Coombes, Rüdiger Thul, Stefan Ruschel +1
We develop a theory of phase-locked activity in delayed spiking networks using the Haken Lighthouse model as an analytically tractable event-based description of neural dynamics. F…
Network Attractors driven by Time-Delay Plasticity
Stefan Ruschel, Emanuil Hristov, Hil G. E. Meijer +2
We develop a framework for collective frequency selection and attractor formation by means of delay plasticity. Specifically, we consider adaptive axonal delays (AADs), motivated b…
Periodic and quasiperiodic traveling waves in nonlinear lattices with odd elasticity
Andrus Giraldo, Stefan Ruschel, Behrooz Yousefzadeh
Discrete nonlinear systems support a rich variety of localized and extended wave phenomena, with their dynamics sensitively dependent on the symmetries of the underlying interactio…
Strongly resonant polarization dynamics of pulse trains in a spin-flip model for an excitable microlaser with delayed self-feedback
Stefan Ruschel, Sylvain Barbay, Neil G. R. Broderick +1
Motivated by recent experimental observations concerning the polarization dynamics in an excitable microlaser with saturable absorber coupled to an external feedback mirror reporte…
Regenerative vectorial breathers in a delay-coupled neuromorphic microlaser with integrated saturable absorber
Stefan Ruschel, Venkata A. Pammi, Rémy Braive +5
We report on the polarization dynamics of regenerative light pulses in a micropillar laser with integrated saturable absorber coupled to an external feedback mirror. The delayed se…
Master stability for traveling waves on networks
Stefan Ruschel, Andrus Giraldo
We present a framework for determining effectively the spectrum and stability of traveling waves on networks with symmetries, such as rings and lattices, by computing master stabil…
Sounding the metabolic orchestra: A delay dynamical systems perspective on the glucose-insulin regulatory response to on-off glucose infusion
Stefan Ruschel, Benoit Huard
We investigate the consequences of periodic, on-off glucose infusion on the glucose-insulin regulatory system on the basis of a system-level mathematical model with two explicit ti…
Pulse-adding of Temporal Dissipative Solitons: Resonant Homoclinic Points and the Orbit Flip of Case B with Delay
Andrus Giraldo, Stefan Ruschel
We numerically investigate the branching of temporally localized, two-pulse periodic traveling waves from one-pulse periodic traveling waves with non-oscillating tails in delay dif…
Nonlinear effects of instantaneous and delayed state dependence in a delayed feedback loop
Antony R. Humphries, Bernd Krauskopf, Stefan Ruschel +1
We study a scalar, first-order delay differential equation (DDE) with instantaneous and state-dependent delayed feedback, which itself may be delayed. The state dependence introduc…
The limits of sustained self-excitation and stable periodic pulse trains in the Yamada model with delayed optical feedback
Stefan Ruschel, Bernd Krauskopf, Neil G. R. Broderick
We consider the Yamada model for an excitable or self-pulsating laser with saturable absorber, and study the effects of delayed optical self-feedback in the excitable case. More sp…
The Spectrum of Delay Differential Equations with Multiple Hierarchical Large Delays
Stefan Ruschel, Serhiy Yanchuk
We prove that the spectrum of the linear delay differential equation with multiple hierarchical large delays $1\llτ_{1}\llτ…
Consequences of delays and imperfect implementation of isolation in epidemic control
Lai-Sang Young, Stefan Ruschel, Serhiy Yanchuk +1
For centuries isolation has been the main control strategy of unforeseen epidemic outbreaks. When implemented in full and without delay, isolation is very effective. However, flawl…
Temporal dissipative solitons in time-delay feedback systems
Serhiy Yanchuk, Stefan Ruschel, Jan Sieber +1
Localized states are a universal phenomenon observed in spatially distributed dissipative nonlinear systems. Known as dissipative solitons, auto-solitons, spot or pulse solutions,…

SIQ: a delay differential equations model for disease control via isolation
Stefan Ruschel, Tiago Pereira, Serhiy Yanchuk +1
Infectious diseases are among the most prominent threats to mankind. When preventive health care cannot be provided, a viable means of disease control is the isolation of individua…
Chaotic bursting in semiconductor lasers
S. Ruschel, S. Yanchuk
We investigate the dynamic mechanisms for low frequency fluctuations in semiconductor lasers subject to delayed optical feedback, using the Lang-Kobayashi model. This system of del…
