Yūji Tachikawa (physicist)

from Wikipedia, the free encyclopedia

Yūji Tachikawa ( Japanese 立 川 裕 二 , Tachikawa Yūji ) is a Japanese theoretical physicist who studies supersymmetric field theories. He is a professor at Tokyo University .

Tachikawa received his master's degree ( Seiberg-Witten theory and instanton counting ) in 2004, did his doctorate in 2006 with Tōru Eguchi at the University of Tokyo and was a post-doctoral student with Nathan Seiberg at the Institute for Advanced Study until 2011 . In 2012 he became Assistant Professor at the Kavli Institute for the Physics and Mathematics of the Universe (IPMU) at the University of Tokyo and shortly afterwards Associate Professor at the elementary particle theory group at the University of Tokyo.

He deals with supersymmetric string theories and gauge theories in different dimensions and with different numbers of supersymmetric charges and found new connections between the theories ( dualities ). Together with Davide Gaiotto and Luis Alday in 2010, he found that six-dimensional N = (2.0) superconformal field theories that are compacted on a surface result in a four-dimensional gauge theory that is based on an AGT correspondence named after the authors with a simple conformal field theory (Liouville field theory) are related to the area.

For 2016 he received the New Horizons in Physics Prize . He is invited speaker at the ICM 2018 (On Categories of Quantum Field Theories).
