  • Early-warning indicators for rate-induced tipping 

    Ritchie, P; Sieber, J (AIP Publishing, 2016-09)
    A dynamical system is said to undergo rate-induced tipping when it fails to track its quasi-equilibrium state due to an above-critical-rate change of system parameters. We study a prototypical model for rate-induced tipping, ...
  • Nonlinear dynamic Interactions between flow-induced galloping and shell-like buckling 

    Thompson, JMT; Sieber, J (Elsevier, 2014-01-13)
    For an elastic system that is non-conservative but autonomous, subjected for example to time-independent loading by a steadily flowing fluid (air or water), a dangerous bifurcation, such as a sub-critical bifurcation, or ...
  • Probability of noise- and rate-induced tipping 

    Ritchie, PDL; Sieber, J (American Physical Society, 2017-05-12)
    We propose an approximation for the probability of tipping when the speed of parameter change and additive white noise interact to cause tipping. Our approximation is valid for small to moderate drift speeds and helps to ...
  • Regular and irregular patterns of self-localized excitation in arrays of coupled phase oscillators. 

    Wolfrum, M; Omel'chenko, OE; Sieber, J (American Institute of Physics (AIP), 2015-05)
    We study a system of phase oscillators with nonlocal coupling in a ring that supports self-organized patterns of coherence and incoherence, called chimera states. Introducing a global feedback loop, connecting the phase ...
