The Galileo Galilei Medal awarded to Professor Juan Martin Maldacena

The Galileo Galilei Medal 2019 was awarded to Juan Martin Maldacena with the following motivation: “For his ground-breaking ideas in theoretical physics, and especially for the discovery of duality between gravity and ordinary quantum field theory, with far-reaching implications.” Born in Buenos Aires in 1968, Juan Martin Maldacena is one of the most influential theoretical physicists in the last decades. His ideas have opened new scenarios in string theory, field theory and quantum gravity. He is currently a member of the Institute for Advanced Study in Princeton (USA).


The Galileo Galilei Institute (GGI) of Florence, founded in 2005 thanks to the partnership between the National Institute of Nuclear Physics (INFN) and Florence University, has been the first European Institute dedicated to organizing and hosting long term workshops dedicated to the field of theoretical physics of fundamental interactions. A Launching Committee was appointed with the task of giving advice about scientific and management structures and of suggesting criteria for the formation of the Scientific and Advisory Committees. The members of the Launching Committee were David Gross, Giuseppe Marchesini, Alfred Mueller, Giorgio Parisi and Gabriele Veneziano (chair). GGI was established in a building owned by the University of Florence on the historic hill of Arcetri, near the house where Galileo spent the last period of his life and died in 1642.

Since 2006 the GGI has been running on average three long term workshops every year together with conferences and smaller scientific activities. In particular several PhD schools have been organized every year on different domains of theoretical physics: string theory, particle, astroparticle and nuclear physics and statistical field theory.

In 2018 the GGI obtained an important recognition, becoming the "Centro Nazionale di Studi Avanzati dell'Istituto Nazionale di Fisica Nucleare" (National Center of Higher Studies of INFN), once again in partnership with the University of Florence. The Institute thus confirmed its status as a point of reference for the international scientific community and as a site dedicated to high-level training of young Italian and foreign researchers. The basic referent of the Center is the INFN National Scientific Committee for Theoretical Physics, which gives its full support to favour the activities of the Institute. Workshop proposals, every year, are analyzed and selected by the GGI Scientific Committee.


Together with the research activities, the Galileo Galilei Institute has recently developed a training program at postgraduate level based on a number of schools. They take place every year during winter, when the Institute is not running research programs. Each school last two-three weeks and is devoted to a specific subject: particle physics, string theory, statistical field theory, nuclear physics, etc.
The schools aim at providing pedagogical introductions on the basic concepts and tools needed for research in theoretical physics, and cover basic as well as advanced topics. Lectures are given at the blackboard and mostly in the morning. The afternoon is devoted to exercises, study and discussions with lecturers and senior participants. A desk and standard research facilities are provided to all students.
The lectures are primarily addressed to Ph.D. students, but participation of postdocs is also encouraged. The courses are officially part of the Italian Ph.D. training program for the Universities that have joined the initiative. In this case, there is the possibility of a final exam with the lecturers.

Theoretical Aspects of Astroparticle Physics, Cosmology and Gravitation
School
Astroparticle Physics, Cosmology and Gravitation are nowadays very active areas of research. The School aims at providing robust and detailed introductions on the basic theoretical concepts and tools needed for performing research in these fields. Gravitational waves of astrophysical and cosmological origin, neutrino physics and astronomy, dark matter and dark energy, galactic and extra-galactic cosmic rays and gamma-rays will be some among the main topics. The lecturers are selected among the best experts of our international communities.

String Theory from a Worldsheet Perspective
Workshop

In the recent years there has been a renewed interest on fundamental aspects of superstring theory in its original perturbative definition on the world-sheet. On the one hand superstring perturbation theory has been a guiding light for important developments in the study of certain types of scattering amplitudes in supersymmetric gauge theories. On the other hand, also thanks to the development of string field theory, some important aspects of the standard on-shell construction of string theory (such as the issue of infrared divergences) have been finally tackled. We are now in a new interesting phase where these new constructions can be finally put to test on concrete examples and this will have important impacts for a top-down approach to string phenomenology and the study of topological string amplitudes. The aim of the proposed workshop is to bring together experts in the world-sheet formulation of String Theory to develop new tools and get new results on fundamental microscopic aspects which include

1. Superstring amplitudes in the RNS formalism and super-moduli space
2. Superstring amplitudes in the pure spinor formulation and the relation to the RNS formulation
3. Ambitwistor string at the quantum level
4. Topological amplitudes and their connection to supersymmetric gauge theories
5. Quantum aspects of closed and open superstring field theory
6. Open string physics and D-branes. Solutions of open superstring field theory
