13 - 15 Sep Perugia, Italy
1981-2021 forty years of Stochastic Resonance
Let's celebrate together with an international conference devoted to noise and its many aspects.


In 2021 it is forty years after the appearance of the first paper on Stochastic Resonance.
Since then, thousands of papers (WOS: 6,968 records, Google Scholar: approx. 40,500 results) have been published on this topic and Stochastic Resonance is nowadays a popular science paradigm and a widespread research subject.

We would like to take the opportunity offered by this anniversary, not only for celebrating this important discovery, with the scientists that mostly contributed over the years to such a great result, starting from Prof. Giorgio Parisi (Chair of the conference), his co-workers, and the many scientists that pioneered this subject, but also to celebrate the science of noise that the Stochastic Resonance phenomenon largely contributed to disseminate.

SR40 is an international conference that has the ambition to be devoted to all phenomena associate with noise, in general and to Stochastic Resonance, in particular. In fact, SR40 aims to bring together leading academic scientists, researchers and research scholars to exchange and share their experiences and research results on all aspects of Noise and Fluctuations, providing a premier interdisciplinary platform for researchers, practitioners and educators to present and discuss the most recent innovations, trends, and concerns as well as practical applications.

Topics to be discussed at SR40 includes:

SR-related (non-exclusive list):

  • SR modelling in classical and quantum realm
  • SR applied to devices
  • SR in biological and neural systems
  • SR in economics and econophysics
  • SR in signal analysis
  • SR in natural phenomena

The science of noise (non-exclusive list):

  • Noise in nonlinear dynamical systems
  • Noise in Energy Harvesting
  • Noise in Epidemics modelling
  • Noise in Artificial Intelligence
  • Noise in structural monitoring
  • Noise in biological systems
  • Noise in neural systems

Submissions on related topics is also welcome.

Detailed agenda will be available upon abstract acceptance

Social Program

On Sept. 12th, we plan to have a welcome cocktail at 18:30, at the conference site.

On Sept. 13th, at the end of the scientific session, at 18:00, there will be plenty of time for enjoying downtown Perugia (at walking distance) with his beautiful locations (the Rocca Paolina, the Corso Vannucci) and museums. Dinner is free and there are a many nice restaurants available at the city center (reservation is recommended).

On Sept. 14th, at 17:00 a touristic excursion is planned, with the social dinner at the beautiful medieval castle Castello di Ramazzano. Transportation to and from the castle, for participants and accompanying persons, is arranged by bus.

On Sept. 15th at 18:30 Giorgio Parisi will give a public lecture on the beginning of the SR adventure. With the participation of Angelo Vulpiani and Roberto Benzi.

Abstract submission

Please mind that all invited and contributed abstracts must be submitted online, by July 31th, via this website only.

Contributed abstracts will have the opportunity to choose between oral or poster presentation.

A selection of the contribute abstracts will be admitted to the SR40 Conference. The outcome of the selection procedure will be communicated within one week from submission.

All the approved presenters must register to the conference, through the conference web site.

Authors will have the possibility to replace the abstract with a short paper (2-3 pages) by October 15th, 2021. The proceedings of the SR40 - forty years of Stochastic Resonance will be peer-reviewed and published on a dedicated community on the online platform Zenodo, which provide citeable DOI references.

Mighty Etruscan centre and important mediaeval city after that, Perugia guards lovingly precious traces of its luminous historical periods. The city is today the administrative and cultural capital of the Umbria Region, a major tourist and cultural destination, site of the University for over 700 years. The historical Academy of Fine Arts, the Music Conservatorium, and its University for Foreigners, with students coming from all over the world, define furthermore the marked international vocation.

The main attraction that you can find at walking distance from the Conference site are the historical-architectural complex of Rocca Paolina, the breathtaking panoramic terrace of Giardini Carducci, together with the medieval Acropolis, a beautiful promenade that bring you to the Fontana Maggiore, the actual "center" of the city.

Hotel information and booking

Excursion and Social Dinner

On the second day of the conference an excursion and social dinner to the Ramazzano Castle is planned. The Ramazzano Castle, to which the town owes its name, was built in the XII century by the Ramazzani family, to which it will belong from 1097 until the end of the sixteenth century. The castle was restored over time, and it preserves the Guelph merlon, the tower, the internal courtyard with a well connected to the basements.

Its ancient bulk overlooks a fertile agricultural area with lush vineyards. Wine and the production of healthy and traditional food has long been the centerpiece of these places.
