Rare events of small-noise Doob conditioned processes
Iago N. Mamede, Francesco Coghi
Doob fixed-time conditioning enables the sampling of rare trajectories of Markov processes by modifying the drift so that reaching a prescribed target at a given time is guaranteed…

Accelerated first-passage dynamics in a non-Markovian feedback Ornstein--Uhlenbeck process
Francesco Coghi, Romain Duvezin, John S. Wettlaufer
We study the first-passage dynamics of a non-Markovian stochastic process with time-averaged feedback, which we model as a one-dimensional Ornstein--Uhlenbeck process wherein the p…

Density-dependent stochastic resetting: a large deviations framework for achieving target distributions over networks
Francesco Coghi, Kristian Stølevik Olsen
We develop a framework for designing density-dependent stochastic resetting protocols to regulate distributions of random walkers on networks. Resetting mechanisms that depend on l…
