Fabio Marchesoni
A graduate of the University of Pisa (Italy), Fabio Marchesoni specializes in areas of nonequilibrium statistical physics including stochastic processes, self-organized criticality, and stochastic resonance. He is co-founder of the VIRGO project, a French-Italian collaboration for the detection of gravitational waves, and has appointments at RIKEN (Japan) and Loughborough University (UK). He is a Fellow of the American Physical Society (2003), the Institute of Physics (IoP, 2004), and the American Association for Advancement of Science (2008), and was named an APS Outstanding Referee (2007). The author is presently professor of physics at the University of Camerino.
Order out of noise
Stochastic resonance, in which a periodic signal applied to a nonlinear system can be amplified by adding noise, has been observed in a mechanical system and predicted to occur in a Bose-Einstein condensate. Read More »
