‎First printing of Hubbard's exceedingly influential paper.""This very mathematical Letter has had a significant impact in all areas of physics and chemistry. The formalism enables the calculation of the thermodynamic properties of quantum-mechanical systems in condensed matter and in quark matter. Hubbard outlines a rederivation of results for the correlation energy of an electron gas, of the Bardeen-Cooper-Schrieffer theory of superconductivity, and of correlations in nuclear matter. The mathematical techniques have also made possible numerical Monte Carlo calculations of the properties of quantum-mechanical systems"".
