Philip Warren Anderson

Brinkman and Ong present an obituary for Philip Warren Anderson, one of the intellectual giants who shaped and nurtured the rapid growth of condensed-matter physics during the second half of the 20th century, who died on 29 March 2020. Anderson made fundamental contributions to diverse subfields, including antiferromagnetism, superexchange, dirty superconductors, the x-ray singularity problem, localization, superfluidity in helium-3, spin glasses, quantum spin liquids, local moments in metals, poor-man's renormalization, and cuprate superconductivity. Many of those concepts now carry his name. He was a corecipient, along with Nevill Mott and John Van Vleck, of the 1977 Nobel Prize in Physics for fundamental theoretical investigations of the electronic structure of magnetic and disordered systems.
