Tai Tsun Wu (simplified Chinese: 吴大峻; traditional Chinese: 吳大峻; pinyin: Wú Dàjùn, December 1, 1933 – July 19, 2024) was a Chinese-born American physicist and writer well known for his contributions to high-energy nuclear physics and statistical mechanics. He was married to experimental physicist Sau Lan Wu.
Life Born in Shanghai, he studied electrical engineering at University of Minnesota and became a William Lowell Putnam Mathematical Competition fellow (1953). He obtained an S.M. (1954) and Ph.D. (1956) in applied physics from Harvard University. His thesis concerned I. The Concept of Impedance II. High Frequency Scattering and was advised by Ronold W. P. King. At Harvard, he continued as Junior Fellow in the Society of Fellows (1956–59), joined the faculty of applied physics (1959) and was the Gordon McKay Professor of Applied Physics & Professor of Physics. Wu has also had visiting appointments with Rockefeller University (1966), at the DESY in Hamburg, Germany (1971), at CERN in Geneva, Switzerland and Utrecht University (1977). He has studied statistical mechanics on Bose–Einstein condensation in an external potential, classical electromagnetic theory (1960). With Hung Cheng, he used gauge quantum field theory to predict the unboundedly increasing total scattering cross sections at very high energies, experimentally verified at CERN and Tevatron collider. Wu studied production processes for the Large Hadron Collider, in particular to predict the production cross section of a Higgs particle with low momentum together with two forward jets. His studies with Chen Ning Yang include CP violation, globalization of the gauge theory, Wu–Yang monopole, and the Wu–Yang dictionary. More recently, Wu has studied quantum information processing based on the Schrödinger equation without any spatial dimension in the modeling and application of quantum memories. He published his last research paper on Concept of the basic standard model and a relation between the three gauge coupling constants at the age of 90 along with his wife Sau Lan Wu. He died on July 19, 2024 at the Stanford Hospital in Palo Alto, California.
