Steven R. White (* 26. December 1959 in Lawton (Oklahoma) ) is an American physicist known for his development of the density matrix - renormalization group .

Live and act

White studied mathematics, physics and economics at the University of California, San Diego (Bachelor 1982, summa cum laude) and received his doctorate from Cornell University with John Wilkins and Kenneth Wilson (New Methods for electronic structure calculations). He was then a postdoc at the University of California at Santa Barbara and from 1989 at the University of California, Irvine , where he was an associate professor from 1993 and a professor since 1997.

White introduced the Density Matrix Renormalization Group (DMRG) in 1992, which proved to be a high-precision numerical variation method for solving, in particular, one- and two-dimensional, strongly correlated quantum mechanical many-particle problems and revolutionized this field. For example, he used it to study high-temperature superconductors in the Hubbard model and was able to show the formation of stripes in the electron distribution. Before that he worked on other numerical methods in many-body quantum mechanics, e.g. B. with quantum Monte Carlo methods for the investigation of strongly correlated electron systems like in high-temperature superconductors (which he later investigated with the DMRG) and already as a student in San Diego with quantum chemical numerical calculations with Kenneth Wilson.

From 1982 to 1985 he was a National Science Foundation Fellow and an IBM Postdoctoral Fellow in 1988/9. In 2003 he received the Aneesur Rahman Prize of the American Physical Society (APS) for his work , of which he became a fellow in 1998. He is Councilor of the APS Division of Computational Physics. In 2016 he was elected a member of the American Academy of Arts and Sciences , and in 2018 of the National Academy of Sciences . For 2019, White was awarded the Feenberg Medal of the International Conference on recent progress in Many Body Theory .
