Takeo Matsubara
Takeo Matsubara was a Japanese physicist. Matsubara proposed a method of statistical mechanics related to Green's function, by applying quantum field theory techniques to statistical physics.
He graduated from Osaka Imperial University, and worked as full professor in Hokkaido University, Kyoto University, and Okayama University of Science. He was the winner of the Nishina Memorial Prize in 1961, and took the directorship of the Physical Society of Japan.
His work with Yukata Toyozawa on impurity bands in semiconductors has led to the Matsubara-Toyozawa model that describes the motion of an electron in a random lattice.
His research interests were dielectric materials, superconductivity and superfluidity. He wrote various physics textbooks in Japanese.
