Ruprecht Machleidt (born December 18, 1943, in Kiel, Germany [1]) is a German-American theoretical nuclear physicist.

Education and CV[edit]

Machleidt studied physics at the University of Bonn, Germany, where he received his master's degree (Diplom-Physiker) in 1971 and his doctorate in 1973. As a postdoc, he continued at the Institute for Theoretical Nuclear Physics at the University of Bonn until 1975. The years 1976 and 1977 he spent at the State University of New York at Stony Brook (SUNY) with the group of Gerry Brown. From 1978 to 1983 he was a research associate (Wissenschaftlicher Assistant) in Bonn. 1983 to 1985 he was a visiting scientist at TRIUMF, University of British Columbia, in Vancouver, Canada, and from 1986 to 1988 at the Los Alamos National Laboratory (at LAMPF), Los Alamos, New Mexico, USA. At the same time, he was an Adjunct Associate Professor at UCLA, Los Angeles. In 1988, he accepted the position of associate professor and in 1991 full professor at the University of Idaho, Moscow, Idaho, USA.


He is known as one of the developers of the Bonn potential [2] to describe the nucleon–nucleon interaction based upon a comprehensive meson exchange model. Next he dealt with nuclear matter, taking into account meson degrees of freedom and relativistic effects (Dirac–Brueckner–Hartree–Fock).[3] Since about 2000, Machleidt's main focus has been the development of nuclear forces based upon chiral effective field theory.[4]
