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…
From trends to optimized forecasts: Quantifying the skill and advancing the utility of dynamics-based early warnings for tipping events
Franco Du Plessis, Victoria Volodina, Chris A. Boulton +5
In this paper we explore and extend the state of the art for understanding the skill and utility of early warnings of critical transitions (tipping points) in forced nonlinear syst…
Variability in a Model of Divergent and Convergent Coupled Ice Streams: Synchronisation, Transients and Chaos
Joshua Grimstead, Peter Ashwin, Tanja I. Schindler
Fast-flowing glaciers, known as ice streams, control the majority of ice sheet mass loss due to thermomechanical coupling at their base, which can induce basal lubrication and high…
Early warnings of critical transitions through vector autoregression: lessons from multiscale systems
Bryony Hobden, Paul Ritchie, Peter Ashwin
In a nonautonomous nonlinear dynamical system, generic critical transitions (tipping points) are not limited to slow passage through fold bifurcations. They can also correspond to…
