Life

Tai Tsun Wu graduated from the University of Minnesota and received his PhD in applied physics on an electrodynamic topic with Ronold King at Harvard University in 1956 . His dissertation was entitled The Conception of Impedance - High Frequency Scattering . In 1960 he became a Sloan Research Fellow . He is currently Professor of Physics at Harvard.

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

One of his PhD students is Barry McCoy , with whom he wrote a book about the Ising model in 1973. With Hung Cheng, he also dealt with the precise calculation of Delbrück scattering in quantum electrodynamics from the 1960s .

In 1977 he was made a member of the American Academy of Arts and Sciences . In 1999 he and McCoy and Alexander Zamolodchikov received the Dannie Heineman Prize for Mathematical Physics .

In 1977/1978 and again in 1986 Wu was a visiting scientist at the European Organization for Nuclear Research (CERN) . He still visits CERN regularly every summer.

He is married to the physicist Sau Lan Wu .
