Yang Zhenning, male, was born in Hefei, Anhui Province on June 1922, 2000 (passport date is September 22nd). He is a physicist, professor of the Chinese University of Hong Kong and director of the Institute of Theoretical Physics, honorary president and professor of the Institute of Advanced Studies of Tsinghua University, honorary professor of the State University of New York at Stony Brook, academician of the China Academy of Sciences, foreign academician of the National Academy of Sciences of the United States, and member of the Royal Society.
1942 graduated from National Southwest Associated University; 1944 master of Tsinghua University; 1945 won the Mu Ou Chu Scholarship to study in the United States. 1948 received his Ph.D. from the University of Chicago, and later served as a lecturer at the University of Chicago and a researcher at the Princeton Institute for Advanced Studies; 1955 Professor, Princeton Institute for Advanced Studies.
From 65438 to 0966, he served as Professor Einstein and Director of the Institute of Theoretical Physics of State University of New York at Stony Brook. From 65438 to 0986, he served as Professor Bowen of the Chinese University of Hong Kong; 1993 Director, Institute of Mathematical Sciences, Chinese University of Hong Kong; 1997, the International Asteroid Center named the asteroid numbered 342 1 "Yang Zhenning Star"; Professor Tsinghua University from 65438 to 0998; In 2022, it was named "Touching China 202 1 Person".
Yang Zhenning has made landmark contributions in particle physics, statistical mechanics and condensed matter physics. In 1950s, he cooperated with R.L. Mills to put forward the theory of non-Abelian gauge field. 1956 cooperated with Li Zhengdao to put forward the law of parity conservation of weak interaction.
Major achievements:
Boson many-body problem. Out of his interest in liquid helium superfluid, Yang Zhenning published or completed a series of papers on thin boson multibody systems with his collaborators around 1957. First, he published two papers with Huang and Luttinger, and applied the pseudopotential method to this field.
After writing the article "Is parity conserved in weak interaction", while waiting for the experimental results, the correct ground state energy correction was obtained by double collision method, and then the same results as Huang and Huang were obtained by pseudo potential method.
Exact solution of boson in repulsive potential of 1 dimensional δ function at finite temperature. In 1969, Yang Zhenning and Yang Zhenping pushed the boson problem in the repulsive potential of 1 dimensional δ function to a finite temperature. This is the first time in history that a quantum statistical model of interaction is obtained at a finite temperature (T >). This model and results were later realized and verified by experiments in the cold atomic system.
