Coupling rare event algorithms with data-based learned committor functions using the analogue Markov chain
Dario Lucente, Joran Rolland, Corentin Herbert +1
Rare events play a crucial role in many physics, chemistry, and biology phenomena, when they change the structure of the system, for instance in the case of multistability, or when…
Instantons and the path to intermittency in turbulent flows
André Fuchs, Corentin Herbert, Joran Rolland +3
Processes leading to anomalous fluctuations in turbulent flows, referred to as intermittency, are still challenging. We consider cascade trajectories through scales as realizations…
Collapse of transitional wall turbulence captured using a rare events algorithm
Joran Rolland
This text presents one of the first successful applications of a rare events method for the study of multistability in a turbulent flow without stochastic energy injection. The tra…
Multistability and rare spontaneous transitions in barotropic -plane turbulence
Eric Simonnet, Joran Rolland, Freddy Bouchet
We demonstrate that turbulent zonal jets, analogous to Jovian ones, which are quasi-stationary, are actually metastable. After extremely long times, they randomly switch to new con…
Machine learning of committor functions for predicting high impact climate events
Dario Lucente, Stefan Duffner, Corentin Herbert +2
There is a growing interest in the climate community to improve the prediction of high impact climate events, for instance ENSO (El-Ni{ñ}o-Southern Oscillation) or extreme events,…
A rare event algorithm links transitions in turbulent flows with activated nucleations
Freddy Bouchet, Joran Rolland, Eric Simonnet
Many turbulent flows undergo drastic and abrupt configuration changes with huge impacts. As a paradigmatic example we study the multistability of jet dynamics in a barotropic beta…
