In what year was the physicist who introduced the 't Hooft operator born?
Gerard 't Hooft Gerardus (Gerard) 't Hooft (] ; born July 5, 1946) is a Dutch theoretical physicist and professor at Utrecht University, the Netherlands. He shared the 1999 Nobel Prize in Physics with his thesis advisor Martinus J. G. Veltman "for elucidating the quantum structure of electroweak interactions".
Gordon Walter Semenoff Gordon Walter Semenoff (born July 11, 1953), {'1': ", '2': ", '3': ", '4': "} , {'1': ", '2': ", '3': ", '4': "} , is a theoretical physicist and Professor of Physics at the University of British Columbia, Canada. He is known for his research on quantum mechanics, quantum field theory, statistical mechanics and string theory and is particularly famous for his co-invention, together with Antti Niemi, of the parity anomaly in odd-dimensional gauge field theories and for his pioneering work on graphene. He is also well known for development of thermal field theory, the application of index theorems and their generalizations in quantum field theory and string theory, notably with respect to the duality between string theories and gauge field theories.
