description: "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. This method, commonly known as Matsubara Green's function technique, introduces the notion of imaginary time, and the reciprocal variable to this imaginary time is known as discrete Matsubara frequency."
