Escape by jumps and diffusion by α-stable noise across the barrier in a double well potential
Ignacio del Amo, Peter Ditlevsen
Many physical and chemical phenomena are governed by stochastic escape across potential barriers. The escape time depends on the structure of the noise and the shape of the potenti…
Warning of a forthcoming collapse of the Atlantic meridional overturning circulation
Peter D. Ditlevsen, Susanne Ditlevsen
Tipping to an undesired state in the climate when a control parameter slowly approaches a critical value is a growing concern with increasing greenhouse gas concentrations. Predict…
Multistability and Intermediate Tipping of the Atlantic Ocean Circulation
Johannes Lohmann, Henk A. Dijkstra, Markus Jochum +2
Tipping points (TP) in climate sub-systems are usually thought to occur at a well-defined, critical forcing parameter threshold, via destabilization of the system state by a single…
Quantification and interpretation of the climate variability record
Anna S. von der Heydt, Peter Ashwin, Charles D. Camp +4
The spectral view of variability is a compelling and adaptable tool for understanding variability of the climate. In Mitchell (1976) seminal paper, it was used to express, on one g…
Refined central limit theorem and infinite density tail of the Lorentz gas from Levy walk
Itzhak Fouxon, Peter Ditlevsen
We consider point particle that collides with a periodic array of hard-core elastic scatterers where the length of the free flights is unbounded (the infinite-horizon Lorentz gas,…
Partial invariants, large-scale dynamo action, and the inverse transfer of magnetic helicity
Nicholas Rathmann, Peter Ditlevsen
The existence of partially conserved enstrophy-like quantities is conjectured to cause inverse energy transfers to develop embedded in magnetohydrodynamical (MHD) turbulence, in an…
