- Michel J. L. Baranger (* 31. Juli 1927 in Le Mans; † 1. Oktober 2014 in Tucson) war ein französisch-amerikanischer theoretischer Physiker. Baranger besuchte die 1945 bis 1949 École normale supérieure und wurde 1951 an der Cornell University bei Hans Bethe mit einer Arbeit über relativistische Korrekturen der Lamb-Verschiebung (die Bethe vorher nicht-relativistisch berechnet hatte) promoviert. In Cornell und danach 1953 bis 1955 am Caltech war er auch Assistent von Richard Feynman. Ab 1955 war er am Carnegie Institute of Technology, wo er 1956 Assistant Professor und 1964 Professor wurde, und ab 1969 Professor am MIT, wo er Professor Emeritus war. Außerdem war er am New England Complex Systems Institute. 1961/62 war er Senior Fellow der National Science Foundation an der Sorbonne. Baranger beschäftigte sich neben Quanten-Elektrodynamik vor allem mit Kernphysik (mikroskopische Theorie von Kernmodellen, kollektive Kernmodelle), ab den 1990er Jahren aber auch mit der nichtlinearen Dynamik und Chaostheorie (Übergang zum Quantenchaos insbesondere in der Vielteilchentheorie, Thermodynamik und Chaos). Er war seit 1951 mit der an der University of Pittsburgh tätigen Physik-Professorin und theoretischen Kernphysikerin Elizabeth Urey Baranger (* 1927) verheiratet und hatte zwei Söhne und eine Tochter. Er war US-amerikanischer Staatsbürger. Er war Fellow der American Physical Society. (de)
- Michel Jacques Louis Baranger (31 July 1927, Le Mans – 1 October 2014, Tucson, Arizona) was a Franco-American theoretical physicist. Baranger matriculated in 1945 at the École normale supérieure, Paris, graduating there in 1949. In 1951 he received from Cornell University his PhD under Hans Bethe with dissertation Relativistic Corrections to the Lamb shift. (Bethe, L. M. Brown, and John R. Stehn had previously calculated a non-relavistic estimate of the Lamb shift.) At Cornell University and then at Caltech from 1953 to 1955, he was also an assistant to Richard Feynman. In 1955 Baranger joined the physics department of Carnegie Institute of Technology, where he became an assistant professor in 1956 and a full professor in 1964. In 1969 he became a professor at MIT, where he retired as professor emeritus in 1997. After retirement from MIT, he worked at the New England Complex Systems Institute and was an adjunct professor at the University of Arizona, Tucson. In 1961/62 he was Senior Fellow of the National Science Foundation at the Sorbonne. His research in the late fifties and sixties in plasma spectroscopy and nuclear collective motion had particular impact. More recently, Baranger had worked in the areas of semi-classical quantum chaos and speciation as a complex system. He was a US citizen. He was elected a Fellow of the American Physical Society in 1968. Upon his death he was survived by two sons, a daughter, four grandchildren, and three former wives: Elizabeth Baranger (born 1927, a physicist and eldest child of Harold Urey), Anne Gerard and Mary Lee Baranger.
