## Life

Tai Tsun Wu gained at the University of Minnesota 's degree and a doctorate in 1956 Ronold King at Harvard University in applied physics via an electrodynamic topic. His dissertation was entitled, The Conception of Impedance - High Frequency Scattering. He is currently professor of physics at Harvard.

Wu worked in the field of high energy physics, where he observed, among others, Cheng of quantum chromodynamics, the much later experimentally, but not previously expected increase of the total cross section in hadron collisions of very high energy, for example in proton -antiproton and proton-proton shocks, previously said. In statistical mechanics, he worked for example on the Ising model, where he studied the asymptotic behavior of various correlation functions by applying the Wiener-Hopf method for solving integral equations, and the Bose -Einstein condensate (BEC ), with the he dealt in an early work in 1959 and he in the 1990s (when the BEC experimentally a very active field of research has been ) treated, among others, in external fields. From the 1990s he was also involved in quantum information theory. With Chen Ning Yang, he gave a new phase factor formulation of Yang-Mills theories and analyzed the CP violation in the kaon anti- kaon system. With Carl M. Bender, he examined from 1969, the asymptotic behavior of the quantum-mechanical perturbation theory ( for example, when the anharmonic oscillator ) at high order.

One of his doctoral students, Barry McCoy, with whom he wrote a book in 1973 about the Ising model. With Hung Cheng he studied in the 1960s, even with the exact calculation of the Delbrück scattering in quantum electrodynamics.

In 1999 he received the Dannie Heineman Prize for Mathematical Physics with McCoy and Alexander Zamolodchikov.
