The effect of timescale separation on the tipping window for chaotically forced systems
Raphael Römer, Peter Ashwin
Tipping behavior can occur when an equilibrium of a dynamical system loses stability in response to a slowly varying parameter crossing a bifurcation threshold, or where noise driv…

Chaotic Kramers' Law: Hasselmann's Program and AMOC Tipping
Jakob Deser, Raphael Römer, Niklas Boers +1
In bistable dynamical systems driven by Wiener processes, the widely used Kramers' law relates the strength of the noise forcing to the average time it takes to see a noise-induced…

Saddle avoidance of noise-induced transitions in multiscale systems
Reyk Börner, Ryan Deeley, Raphael Römer +3
In multistable dynamical systems driven by weak Gaussian noise, transitions between competing states are often assumed to pass via a saddle on the separating basin boundary. By con…
