Quasi-potential and drift decomposition in stochastic systems by sparse identification
Leonardo Grigorio, Mnerh Alqahtani
The quasi-potential is a key concept in stochastic systems as it accounts for the long-term behavior of the dynamics of such systems. It also allows us to estimate mean exit times…

Extreme events and instantons in Lagrangian passive scalar turbulence models
Mnerh Alqahtani, Leonardo Grigorio, Tobias Grafke
The advection and mixing of a scalar quantity by fluid flow is an important problem in engineering and natural sciences. If the fluid is turbulent, the statistics of the passive sc…

Instantons for rare events in heavy-tailed distributions
Mnerh Alqahtani, Tobias Grafke
Large deviation theory and instanton calculus for stochastic systems are widely used to gain insight into the evolution and probability of rare events. At its core lies the realiza…
