Angelo Vulpiani is a distinguished theoretical physicist known for his contributions to chaos theory, complexity, and non-equilibrium systems. He earned his degree in Physics from the University of La Sapienza in Rome in 1977, where he later became a Full Professor of Theoretical Physics. His research spans stochastic resonance, multifractal analysis in turbulence, diffusion, and transport in chaotic systems, and the application of non-equilibrium statistical mechanics to a wide range of physical and biological phenomena.

Vulpiani has published over 300 papers and authored 11 books, with his work cited nearly 25,000 times. His achievements have earned him numerous accolades, including the 2021 Statistical and Nonlinear Physics Prize from the European Physical Society and the 2023 Richardson Medal from the European Geosciences Union. In addition to his academic positions at La Sapienza, Vulpiani has been a key figure at international institutions such as the GSSI in L'Aquila and the John Bell Institute. His pioneering work continues to shape the understanding of complex dynamical systems in both theory and application.


Abstract:

In physics noise is usually associated with small and fast perturbations on the system under study, i.e. something we want to get rid off. However, in complex systems, like turbulent flows and climate dynamics, noise should be considered as the result of different dynamical processes which we cannot neglect. In this talk I discuss the effect of climate noise: after a short review of the paleoclimatic data and the pioneering work of Hasselmann, I describe the mechanism of Stochastic Resonance and its relevance in climate changes.
