Giorgio Parisi (born 4 August 1948) is an Italian theoretical physicist, whose research has focused on quantum field theory, statistical mechanics and complex systems. His best known contributions are the QCD evolution equations for parton densities, obtained with Guido Altarelli, known as the Altarelli–Parisi or DGLAP equations, the exact solution of the Sherrington–Kirkpatrick model of spin glasses, the Kardar–Parisi–Zhang equation describing dynamic scaling of growing interfaces, and the study of whirling flocks of birds.

Career highlights

Giorgio Parisi received his degree from the University of Rome La Sapienza in 1970 under the supervision of Nicola Cabibbo. He was a researcher at the Laboratori Nazionali di Frascati (1971–1981) and a visiting scientist at the Columbia University (1973–1974), Institut des Hautes Études Scientifiques (1976–1977), and École Normale Supérieure (1977–1978). From 1981 until 1992 he was a full professor of Theoretical Physics at the University of Rome Tor Vergata and he is now professor of Quantum Theories at the Sapienza University of Rome. He is a member of the Simons Collaboration "Cracking the Glass Problem". In 2018 he was elected president of the Accademia dei Lincei.

Honors and awards

Giorgio Parisi is a member of the Accademia dei Lincei and a foreign member of the French Academy of Sciences, the American Philosophical Society, and the United States National Academy of Sciences.

• Feltrinelli Prize, 1986.
• Boltzmann Medal, 1992.

"The Boltzmann Medal for 1992 is awarded to Giorgio Parisi for his fundamental contributions to statistical physics, and particularly for his solution of the mean field theory of spin glasses."

• Dirac Medal of the ICTP, 1999.

"Giorgio Parisi is distinguished for his original and deep contributions to many areas of physics ranging from the study of scaling violations in deep inelastic processes (Altarelli–Parisi equations), the proposal of the superconductor's flux confinement model as a mechanism for quark confinement, the use of supersymmetry in statistical classical systems, the introduction of multifractals in turbulence, the stochastic differential equation for growth models for random aggregation (the Kardar–Parisi–Zhang equation) and his groundbreaking analysis of the replica method that has permitted an important breakthrough in our understanding of glassy systems and has proved to be instrumental in the whole subject of Disordered Systems."

• Enrico Fermi Prize, 2002.

"For his contributions to field theory and statistical mechanics, and in particular for his fundamental results concerning the statistical properties of disordered systems."

• Dannie Heineman Prize for Mathematical Physics, 2005.

"For fundamental theoretical discoveries in broad areas of elementary particle physics, quantum field theory, and statistical mechanics; especially for work on spin glasses and disordered systems."

• Nonino Prize “An Italian Master of our Time”, 2005.

"World-famous theoretic physicist, Giorgio Parisi is an investigator of the unpredictable, this means of all that happens in the real world and of its probable laws. A pioneer of complexity, his research of rules and balances inside chaotic systems hypothesizing mathematical instruments, may take to great discoveries in all the fields of human knowledge, from immunology to cosmology. His is a research of the next “Ariadne’s thread” of the labyrinth of our existence."

• Microsoft Award, 2007.

"He has made outstanding contributions to elementary particle physics, quantum field theory and statistical mechanics, in particular to the theory of phase transitions and replica symmetry breaking for spin glasses. His approach of using computers to corroborate the conclusions of analytical proofs and to actively motivate further research has been of fundamental importance in his field."

• Lagrange Prize, 2009. Awarded to scientists who have contributed most to the development of the science of complexity in various areas of knowledge.

• Max Planck Medal, 2011.

“For his significant contributions in theoretical elementary particle physics and quantum field theory and statistical physics, especially of systems with frozen disorder, especially spin glasses."

• Nature Awards for Mentoring in Science – Italy, 2013 Lifetime achievement award. The Prize is awarded annually to a different country by the scientific journal "Nature".

• High Energy and Particle Physics Prize - EPS HEPP Prize, 2015.

“For developing a probabilistic field theory framework for the dynamics of quarks and gluons, enabling a quantitative understanding of high-energy collisions involving hadrons”.

• Lars Onsager Prize, 2016.

“For groundbreaking work applying spin glass ideas to ensembles of computational problems, yielding both new classes of efficient algorithms and new perspectives on phase transitions in their structure and complexity”.

• Pomeranchuk Prize, 2018.

“For outstanding results in quantum field theory, statistical mechanics and particle theory”.

• Wolf Prize, 2021.

“For ground-breaking discoveries in disordered systems, particle physics and statistical physics. The Wolf Prize in Physics is awarded to Giorgio Parisi for being one of the most creative and influential theoretical physicists in recent decades. His work has a large impact on diverse branches of physical sciences, spanning the areas of particle physics, critical phenomena, disordered systems as well as optimization theory and mathematical physics.”.

Activism

Since 2016, Giorgio Parisi has been leading the movement "Salviamo la Ricerca Italiana" to put pressure on the Italian and European governments to start funding basic research above the subsistence level.
