Fast-slow partially hyperbolic systems versus Freidlin-Wentzell random systems
Jacopo de Simoi, Carlangelo Liverani, Christophe Poquet +1
We consider a simple class of fast-slow partially hyperbolic dynamical systems and show that the (properly rescaled) behaviour of the slow variable is very close to a Friedlin--Wen…
On the relaxation rate of short chains of rotors interacting with Langevin thermostats
Noé Cuneo, Christophe Poquet
In this short note, we consider a system of two rotors, one of which interacts with a Langevin heat bath. We show that the system relaxes to its invariant measure (steady state) no…
Small noise and long time phase diffusion in stochastic limit cycle oscillators
Giambattista Giacomin, Christophe Poquet, Assaf Shapira
We study the effect of additive Brownian noise on an ODE system that has a stable hyperbolic limit cycle, for initial data that are attracted to the limit cycle. The analysis is pe…
