Part I: Physical Chemistry. Part II: Solid State Physics [Paperback]

The fourth volume of the Collected Works is devoted to Wigners contribution to physical chemistry, statistical mechanics and solid-state physics. One corner stone was his introduction of what is now called the Wigner function, while his paper on adiabatic perturbations foreshadowed later work on Berry phases. Although few in number, Wigners articles on solid-state physics laid the foundations for the modern theory of the electronic structure of metals.I Physical Chemistry.- Wigner on Physical Chemistry.- On Electrical Phenomena in Sols with Rod-Shaped Particles / ?ber elektrische Erscheinungen bei St?bchensolen.- The Lattice Structure of Rhombic Sulfur / Die Gitterstruktur des rhombischen Schwefels.- Formation and Decay of Molecules / Bildung und Zerfall von Molek?len.- On the Interference of Eigenvibrations as a Cause of Energy Fluctuations and Chemical Reactions / ?ber die Interferenz von Eigenschwingungen als Ursache von Energieschwankungen und chemischer Umsetzungen.- The Statistics of Composite Systems According to the New Quantum Mechanics / Statistik zusammengesetzter Systeme nach der neueren Quanten-Mechanik.- On the Rate Constants of Exchange Reactions / ?ber die Geschwindigkeitskonstante von Austauschreaktionen.- On Crossing Over Potential Barriers in Chemical Reactions / ?ber das ?berschreiten von Potentialschwellen bei chemischen Reaktionen.- On the Quantum Correction for Thermodynamic Equilibrium.- Contributions to the Theory of the Neutron / Beitr?ge zur Theorie des Neutrons.- On the Paramagnetic Transition of Para-Ortho-Hydrogen.
