1, phase transition theory. Statistical mechanics is one of the main research directions of Yang Zhenning. His characteristic in statistical mechanics is to strictly solve and analyze the general model rooted in physical reality, so as to grasp the essence and essence of the problem.

2. 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.

3. Exact solution of boson in the repulsive potential of 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.

Yang Zhenning,1June 1922+1 year1October was born in Hefei, Anhui Province, and is a world-famous physicist. He is currently a professor at the Chinese University of Hong Kong, an emeritus professor at the State University of New York at Stony Brook, a member of the China Academy of Sciences, a member of the National Academy of Sciences of the United States and a member of the Taiwan Academia Sinica.

Extended data role impact:

1On May 25th, 997, China Academy of Sciences and Jiangsu Provincial People's Government announced that the International Asteroid Center discovered the Purple Mountain Observatory of China Academy of Sciences at 10/975165438+on October 26th, and the asteroid with the international number of 342 1 was officially named as.

Character evaluation:

Gu, former president of Tsinghua University, spoke highly of it, saying that "Mr. Yang is a banner of China scientists". Gu revealed that when Yang Zhenning was president, he recommended famous computer experts to teach in Tsinghua, which played a very important role in introducing a large number of high-end talents to Tsinghua. "He also donated his salary in Tsinghua, introduced talents and trained students."
