David Pines (June 8, 1924 – May 3, 2018) was a US physicist recognized for his work in quantum many-body systems in condensed matter and nuclear physics.
[2][3] Pines extended BCS theory to nuclear physics to explain stability of isotopes with even and odd numbers of nucleons.
"[7] Although Pines justified his etymological choice by making the term a half backronym (from D.E.M., which he claimed stood for "distinct electron motion"), the phenomenon is unrelated to Maxwell's statistical mechanics demon.
Some recent research results on correlated electron materials are the development of a consistent phenomenological description of protected magnetic behavior in the pseudogap state of underdoped cuprate superconductors and the discovery of the protected emergence of itinerancy in the Kondo lattice in heavy electron materials and its description using a two-fluid model.
He remained interested in the superfluidity of neutron stars revealed by pulsar glitches and in elementary excitations in the helium liquids.
