With the passing away of Robert Schrieffer a few days ago, one of the pioneering figures in modern theoretical physics is no more. Schrieffer, as a Ph D student, working with his mentor John Bardeen and postdoctoral colleague Leon Cooper, gave to the world the microscopic theory of superconductivity in 1957. (Their theory, unbreakably supported by a host of experiments, is considered the gold standard for the atomic-level understanding of the behaviour of electrons in matter, indeed of all fermions.) The flow of electrical current without any resistance, suddenly turning on in a very cold metal (close to, but above the absolute zero of temperature) is one of the most spectacular and mysterious phenomena in physical sciences. Discovered in 1911, its seductive appeal lured almost all the great names of physics into (unsuccessful) efforts at making sense of the phenomenon.Full Text

P. W. Anderson, an epochal figure in Physics, passed away on 29 March 2020, at the age of 96, at Princeton, NJ, USA. He was awarded the Nobel Prize in Physics in 1977 (which he shared with N. F. Mott and J. H. van Vleck ‘for their fundamental theoretical investigations of the electronic structure of magnetic and disordered systems’). Anderson was named the most creative living physicist in a statistical survey in 2006. His foundational contributions, perhaps more than those of anyone else, transformed the field of condensed matter physics from obscurity to prominence. Even the name ‘Condensed matter physics’ is due to him1 .Full Text

- Anderson and Volker Heine renamed their group in Cambridge, originally called ‘solid state theory’, as ‘theory of condensed matter’ in 1967. This is the current name for the field, which is concerned with the ‘condensed’ phases that appear whenever the number of constituents in a system is extremely large and the interactions between the constituents are strong.
