Ryogo Kubo

Japanese physicist

In this Japanese name, the surname is Kubo.

Ryogo Kubo (久保亮五, Kubo Ryōgo, February 15, 1920 – March 31, 1995) was a Japanese mathematical physicist, best known for his works in statistical physics and non-equilibrium statistical mechanics.

Work

In the early 1950s, Kubo transformed research into the linear response properties of near-equilibrium condensed-matter systems, in particular the understanding of electron transport and conductivity, through the Kubo formalism, a Green's function approach to linear response theory for quantum systems. In 1977 Ryogo Kubo was awarded the Boltzmann Medalfor his contributions to the theory of non-equilibrium statistical mechanics, and to the theory of fluctuation phenomena. He is cited particularly for his work in the establishment of the basic relations between transport coefficients and equilibrium time correlation functions: relations with which his name is generally associated.

Ryogo Kubo (February 15, 1920 - March 31, 1995) was a Japanese theoretical physicist, best known for his works in statistical physics and statistical mechanics.
Ryogo Kubo studied physics at the University of Tokyo, (Master degree 1941). Since then he worked at the University of Tokyo (from 1954 professor of physics). His Ph.D. thesis was devoted to the polymer physics. Then he worked with K. Tomita on the statistical theory of nuclear spin resonance and relaxation. An improvement in the general formulation of the theory was achieved by Kubo and Tomita in their treatment of magnetic resonance absorption via a linear theory of irreversible processes. In this theory the important quantities are frequency-dependent susceptibilities which are expressed in terms of spin correlation functions.
In the early 1950s, Kubo made a series of important research on the theory the response properties of near-equilibrium condensed-matter systems, in particular the understanding of electron transport and conductivity, through the Kubo formalism, the Green's functions approach to linear respon
