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 widelyâÂÂhis most cited article has received over seven thousand citations.
