We would like to congratulate our longstanding colleague, Giorgio Parisi, Sapienza University of Rome, Italy, who has been awarded one half of the Nobel Prize in Physics 2021 “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales”. He shares this wonderful award with Syukuro Manabe and Klaus Hasselmann who, together with Professor Parisi, have been recognised “for groundbreaking contributions to our understanding of complex physical systems”.

Professor Parisi has published extensively with EDP Sciences and his work is still available today. In the prestigious Journal de Physique archives, his articles include "Replica field theory for random manifolds" (here), "Recipes for Metastable States in Spin Glasses" (here) and “On the replica approach to random directed polymers in two dimensions” (here). All are currently available to read freely. In EPJ B, part of the European Physical Journal, his contributions include "On the finite size corrections to some random matching problems" (here) and "Renormalization group approach to spin glass systems" (here).

Giorgio Parisi was also very involved with EPL from the very start in 1986. He published many papers in the journal including “The large-connectivity limit of bootstrap percolation” (here) and “One-loop topological expansion for spin glasses in the large connectivity limit” (here). He was Advisory Editor from 1986 to 2001.

We are truly delighted by the news from Stockholm and very pleased for Professor Parisi and all of this year’s laureates. This is, in fact, the fourth year in a row we are celebrating the achievements of our authors in relation to the Nobel Prize in Physics. In 2018, Gérard Mourou (and Donna Strickland) was recognised “for their method of generating high-intensity, ultra-short optical pulses”. In 2019, we celebrated when Michel Mayor and Didier Queloz received the award “for the discovery of an exoplanet orbiting a solar-type star”. Last year, we were jumping up and down again when Reinhard Genzel and Andrea Ghez were awarded “for the discovery of a supermassive compact object at the centre of our galaxy”. We are so proud of all our authors and thank them for their contributions which sometimes really do change the world.
