Schwinger, Julian


Born Feb. 12, 1918, in New York. American physicist.

After receiving the Ph.D. degree from Columbia University in 1939, Schwinger worked at the University of California (Berkeley), Cambridge University, the University of Chicago, and Boston University. From 1943 to 1946 he worked at the Radiation Laboratory of the Massachusetts Institute of Technology. From 1947 to 1972 he was a professor at Harvard University. In 1972 he became a professor at the University of California (Los Angeles).

Schwinger’s main works deal with quantum field theory, the theory of nuclear forces, the theory of scattering and radiation, and the quantum theory of many-particle systems based on Green functions. Schwinger was the first to set down the foundations of quantum electrodynamics in covariant form and to calculate a number of radiation corrections. Schwinger worked out the variational method in the theory of scattering.

In 1965, Schwinger, R. P. Feynman, and S. Tomonaga were awarded a Nobel Prize. Schwinger is a member of the US National Academy of Sciences and the American Academy of Arts and Sciences.

To see what emerges from two entangled quarks, he first generated quarks using the Schwinger effect -- a concept in quantum theory that enables one to create particles out of nothing.
Many phenomena, ranging from the BCS theory of superconductivity [51] to the Casimir and the Schwinger effects [50], are represented, in the context of QFT, by a Bogoliubov transformation [55].
