Davide Gaiotto

from Wikipedia, the free encyclopedia

Davide Silvano Achille Gaiotto (born March 11, 1977 ) is an Italian theoretical physicist who deals with quantum field theories and string theory.

Gaiotto won the silver medal as an Italian participant in the International Mathematical Olympiad in 1996 and the gold medal at the International Physics Olympiad in Canberra in 1995. He received his PhD from Princeton University in 2004 with Leonardo Rastelli . At that time he dealt with string field theories (field theory of open bosonic strings), where he worked with Rastelli and Ashoke Sen and Barton Zwiebach . From 2004 to 2007 he was a post-doctoral student at Harvard University and then until 2011 at the Institute for Advanced Study , where he worked with Edward Witten , among others . Since 2011 he has been at the Perimeter Institute for Theoretical Physics in Waterloo (Ontario) .

He introduced new techniques for studying and constructing four-dimensional (N = 2) supersymmetric conformal field theories. He constructed them from M5 branes, which are wrapped around Riemann surfaces with dots. This led to new insights into the dynamics of four-dimensional (supersymmetric) gauge theories. With Juan Maldacena he studied these gauge theories with the help of the gravitation theories associated with the AdS-CFT correspondence . In 2010 he introduced the AGT correspondence (named after the authors) with Yuji Tachikawa and Luis Alday , a duality in the six-dimensional N = (0.2) superconforming field theory with compactification on a surface to a simple conformal field theory on the surface (Liouville Field theory). In the original model, compactification resulted in four-dimensional gauge theories; later he and colleagues also applied this to three-dimensional gauge theories

In 2012 he received the New Horizons in Physics Prize and in 2011 the Gribov Medal for uncovering new facets of the dynamics of four-dimensional supersymmetric gauge field theories and specifically for discovering a large class of four-dimensional superconformal theories and for discovering important intricate relationships between two-dimensional theories of gravity and four-dimensional gauge field theories .
