Data-driven analysis of metastability in a stochastic bistable system
Ankan Banerjee, Manuel Santos Gutierrez, John Moroney +1
The paper introduces a data‑driven method using the Koopman operator to identify slow inter‑well transitions and fast saddle escapes in a stochastic bistable system, validating esc…
Markov matrix perturbations to optimize dynamical and entropy functionals
Manuel Santos Gutierrez, Niccolo Zagli, Giulia Carigi
An important problem in applied dynamical systems is to compute the external forcing that provokes the largest response of a desired observable quantity. For this, we investigate t…
A General Framework for Linking Free and Forced Fluctuations via Koopmanism
Valerio Lucarini, Manuel Santos Gutierrez, John Moroney +1
The link between forced and free fluctuations for nonequilibrium systems can be described via a generalized version of the celebrated fluctuation-dissipation theorem. The use of th…
