Charged Deformation of a Hairy Black Brane: Perturbative Solution and Thermodynamics
Sangheon Yun
We study electrically charged black branes in four-dimensional Einstein-Maxwell-scalar theory with Maxwell coupling , whose potential has an AdS fixed point…
Global continuation as a complement to traditional continuation and bifurcation analysis
George Datseris, Andreas Morr, Muhammed Fadera +1
Multistable dynamical systems are ever-prevalent, used to model for example ecosystems, power grids, climate elements, neurons, and more. When perturbed, such systems may ``tip'' f…
Estimating the Resilience of Non-Stationary Systems
Taylor Smith, Andreas Morr, Christof Schötz +1
A wide body of work has applied the concept of critical slowing down to estimate the stability of different Earth system components. Most of them -- such as global vegetation -- ar…
Extrapolation from historical data cannot reliably predict the time of a potential AMOC collapse
Andreas Morr, Maya Ben-Yami, Brian Groenke +6
Ditlevsen and Ditlevsen [Nature Communications, 2023] (DD23 hereafter) propose a statistical framework to estimate the timing of a potential collapse of the Atlantic Meridional Ove…
Statistical warning indicators for abrupt transitions in dynamical systems with slow periodic forcing
Florian Suerhoff, Andreas Morr, Sebastian Bathiany +2
There is growing interest in anticipating critical transitions in natural systems, often pursued through statistical detection of early warning signals associated with dynamical bi…
Computing Resilience Measures in Dynamical Systems
Andreas Morr, Christian Kuehn, George Datseris
Resilience broadly describes a quality of withstanding perturbations. Measures of system resilience have gathered increasing attention across applied disciplines, yet existing metr…
Predicting Instabilities in Transient Landforms and Interconnected Ecosystems
Taylor Smith, Andreas Morr, Bodo Bookhagen +1
Many parts of the Earth system are thought to have multiple stable equilibrium states, with the potential for rapid and sometimes catastrophic shifts between them. The most common…
The influence of data gaps and outliers on resilience indicators
Teng Liu, Andreas Morr, Sebastian Bathiany +5
The resilience, or stability, of major Earth system components is increasingly threatened by anthropogenic pressures, demanding reliable early warning signals for abrupt and irreve…
Critical Slowing Down in Bifurcating Stochastic Partial Differential Equations with Red Noise
Paolo Bernuzzi, Christian Kuehn, Andreas Morr
The phenomenon of critical slowing down (CSD) has played a key role in the search for reliable precursors of catastrophic regime shifts. This is caused by its presence in a generic…
Discontinuous stochastic forcing in Greenland ice core data
Keno Riechers, Andreas Morr, Klaus Lehnertz +4
Paleoclimate proxy records from Greenland ice cores, archiving e.g. O as a proxy for surface temperature, show that sudden climatic shifts called Dansgaard-Oeschger events…
Internal noise interference to warnings of tipping points in generic multi-dimensional dynamical systems
Andreas Morr, Niklas Boers, Peter Ashwin
A deterministic dynamical system that slowly passes through a generic fold-type (saddle-node) bifurcation can be reduced to one-dimensional dynamics close to the bifurcation becaus…
Measuring tropical rainforest resilience under non-Gaussian disturbances
Vitus Benson, Jonathan F. Donges, Niklas Boers +5
The Amazon rainforest is considered one of the Earth's tipping elements and may lose stability under ongoing climate change. Recently a decrease in tropical rainforest resilience h…
Detection of Approaching Critical Transitions in Natural Systems Driven by Red Noise
Andreas Morr, Niklas Boers
Detection of critical slowing down (CSD) is the dominant avenue for anticipating critical transitions from noisy time-series data. Most commonly, changes in variance and lag-1 auto…
Uncertainties too large to predict tipping times of major Earth system components from historical data
Maya Ben-Yami, Andreas Morr, Sebastian Bathiany +1
One way to warn of forthcoming critical transitions in Earth system components is using observations to detect declining system stability. It has also been suggested to extrapolate…
Anticipating critical transitions in multidimensional systems driven by time- and state-dependent noise
Andreas Morr, Keno Riechers, Leonardo Rydin Gorjão +1
Anticipating bifurcation-induced transitions in dynamical systems has gained relevance in various fields of the natural, social, and economic sciences. Before the annihilation of a…
Red noise in continuous-time stochastic modelling
Andreas Morr, Dörte Kreher, Niklas Boers
The concept of time-correlated noise is important to applied stochastic modelling. Nevertheless, there is no generally agreed-upon definition of the term red noise in continuous-ti…
