Unification With The RITP in Hiroshima (1990)
The new English name, the Yukawa Institute for Theoretical Physics, was adopted after the unification of two institutions: the Research Institute for Theoretical Physics (RITP) of Hiroshima University and Research Institute for Fundamental Physics (RIFP).
RITP of Hiroshima University was founded in 1944 by Yoshitaka Mimura for the research of mathematical foundations of theoretical physics. On August 6, 1945, it lost two faculty members and a supporting staff, together with all its facilities, by the blast of the atomic bomb exploded over Hiroshima.
RITP was re-established in 1948 in Takehara, a quiet suburban town of Hiroshima near the water, and stayed there until it was dissolved by the unification in 1990.
A major expansion of the institute took place in 1990 when Research Institute for Fundamental Physics (RIFP) was joined by all academic staff members of the Research Institute for Theoretical Physics (RITP) of Hiroshima University. At the time of the unification, RITP had ten academic staffs and its research area had expanded to include cosmology, general relativity, field theory, and particle theory.
