Steven R. White

Steven R. White is a professor of physics at the University of California, Irvine. He is a condensed matter physicist who specializes in the simulation of quantum systems. He graduated from the University of California, San Diego; he then received his Ph.D. at Cornell University, where he was a shared student with Kenneth Wilson and John Wilkins.

He works mostly in condensed matter theory, specializing in computational techniques for strongly correlated systems. These strongly correlated systems include both high-temperature superconductors and quantum spin liquids. He is most known for inventing the Density Matrix Renormalization Group (DMRG) in 1992. This is a numerical variational technique for high accuracy calculations of the low energy physics of quantum many-body systems. His over one hundred seventy papers on this and related subjects have been used and cited widely—his most cited article has received over seven thousand citations. Provided by Wikipedia
