Bunji Sakita

Bunji Sakita (Japanese崎 田 文 二, Sakita Bunji; * 1930 in Toyama prefecture, Japan, † August 31 2002 in Japan) was a Japanese- American theoretical physicist.

Sakita studied at the University of Kanazawa ( pre-degree 1953) and then at Shoichi Sakata at Nagoya University, where he graduated in 1956 be. At the invitation of Robert Marshak he was then at the University of Rochester ( where at the time already George Sudarshan and Susumu Okubo were ), where he received his doctorate in 1959 at Charles Goebel (The Application of Dispersion Relations to Leptonic Decays ). After that, he was at the University of Wisconsin -Madison, where he became a professor. In 1964 he was at the Argonne National Laboratory. 1970 brought him Robert Marshak at the City College of New York, where he led the group of Theoretical Physics and Distinguished Professor of Physics was.

Sakita developed in the 1960s, Picking up ideas of Eugene Paul Wigner, a quark model with the group SU ( 6) spin and isospin united ("super - multiplets "). In 1967 he met on a trip ( at the invitation of Harry Lipkin on Weimann Institute, where he met with Miguel Virasoro and Gabriele Veneziano, while the Israeli physicists were in the Six Day War) to Israel Dual models, the precursor of string theory know, and developed with Keiji Kikkawa Miguel Virasoro, Chen- Shiung Hsue, Jean- Loup Gervais and other methods for calculating their loop diagrams (loop diagrams). In 1971, he presented with Gervais on a supersymmetric Lagrangian density in the context of string theory and joined so that the early pioneers of supersymmetry one. Sakita turned functional integral methods not only in string theory ( with Gervais ) and meson - field theories of nuclear physics, but also on collective excitations in many-body physics. In the 1990s he studied, among others, the fractional quantum Hall effect ( FQHE ) and charge - density waves (Charge Density Waves ). He extended his theory of collective coordinates on fermions. With Gervais he developed in the late 1970s a field theory for solitons and with Jevicki he examined the limiting case of many color degrees of freedom in matrix models. With Rabindra Mohapatra he dealt with GUTs.

In 1970 he was Guggenheim Fellow, 1974, he was awarded the Japanese Nishina price.
