Many Body Theory Of Molecules Clusters And Condensed Phases

This book provides a comprehensive review of seminal as well as recent results in the theory of condensed phases, including liquid metals, quantum liquids and Wigner crystals, along with selected applications, especially in the physical chemistry of molecules and clusters. A large part of this work is dedicated to the Thomas-Fermi semiclassical approximation for molecules and condensed phases, and its extension to inhomogeneous electron liquids and liquid metals. Correlation effects in quantum liquids and Wigner crystallization are other areas of focus of this work, with an emphasis towards the effect of low dimensionality and magnetic fields. The volume is a collection of reprints by N H March and collaborators over five decades. Sample Chapter(s). Chapter 1: Kinetic and Potential Energies of an Electron Gas (761 KB). Contents: Quantal Electron Crystals; Structure, Forces and Electronic Correlation Functions in Liquid Metals: Nuclear Structure Factor and Pair Potentials in Some sp Liquid Metals; Electronic Correlation Functions in Liquid Metals; One-Body Potential Theory of Molecules and Condensed Matter: ThomasOCoFermi Semiclassical Approximation; Transcending ThomasOCoFermi Theory; Applications of One-Body Potential Theory: Local and Non-local. Readership: Graduate students, researchers and academics in theoretical physics; condensed matter theorists and quantum chemists."

The book reviews several theoretical, mostly exactly solvable, models for selected systems in condensed states of matter, including the solid, liquid, and disordered states, and for systems of few or many bodies, both with boson, fermion, or anyon statistics. Some attention is devoted to models for quantum liquids, including superconductors and superfluids. Open problems in relativistic fields and quantum gravity are also briefly reviewed. The book ranges almost comprehensively, but concisely, across several fields of theoretical physics of matter at various degrees of correlation and at different energy scales, with relevance to molecular, solid-state, and liquid-state physics, as well as to phase transitions, particularly for quantum liquids. Mostly exactly solvable models are presented, with attention also to their numerical approximation and, of course, to their relevance for experiments.

The theoretical methods of quantum chemistry have matured to the point that accurate predictions can be made and experiments can be understood for a wide range of important gas-phase phenomena. A large part of this success can be attributed to the maturation of hierarchies of approximation, which allow one to approach very high accuracy, provided t

This book presents a collection of invited research and review contributions on recent advances in (mainly) theoretical condensed matter physics, theoretical chemistry, and theoretical physics. The volume celebrates the 90th birthday of N.H. March (Emeritus Professor, Oxford University, UK), a prominent figure in all of these fields. Given the broad range of interests in the research activity of Professor March, who collaborated with a number of eminent scientists in physics and chemistry, the volume embraces quite diverse topics in physics and chemistry, at various dimensions and energy scales. One thread connecting all these topics is correlation in aggregated states of matter, ranging from nuclear physics to molecules, clusters, disordered condensed phases such as the liquid state, and solid state physics, and the various phase transitions, both structural and electronic, occurring therein. A final chapter leaps to an even larger scale of matter aggregation, namely the universe and gravitation. A further no less important common thread is methodological, with the application of theoretical physics and chemistry, particularly density functional theory and statistical field theory, to both nuclear and condensed matter.

This book addresses a wide range of topics relating to the properties and behavior of condensed matter under extreme conditions such as intense magnetic and electric fields, high pressures, heat and cold, and mechanical stresses. It is divided into four sections devoted to condensed matter theory, molecular chemistry, theoretical physics, and the philosophy and history of science. The main themes include electronic correlations in material systems under extreme pressure and temperature conditions, surface physics, the transport properties of low-dimensional electronic systems, applications of the density functional theory in molecular systems, and graphene. The book is the outcome of a workshop held at the University of Catania, Italy, in honor of Professor Renato Pucci on the occasion of his 70th birthday. It includes selected invited contributions from collaborators and co-authors of Professor Pucci during his long and successful career, as well as from other distinguished guest authors.

Yoichiro Nambu was one of the giants in the physics of the last century. His profound ideas in fundamental physics are still playing an important role and are being rediscovered over and over again.He preferred to share some of his deepest insights in talks, rather than publications, but Nambu's papers and talks were not easy to understand. Like the Japanese gentleman he was, he did not want to humiliate the reader with obvious statements. Even if it is an interpretation, it fits very well with his character of a very polite and considerate human being with a self-reliance inside him that he did not show on the outside. It is no wonder that many of his breakthroughs were not immediately appreciated by his contemporaries, with a late award of a well-deserved Nobel Prize. He was probably the only one in the highest stratum of physicists who was respected by everybody.The purpose of this book, half-history, half-physics is to trace Nambu's progress formulating some of his greatest ideas. It is structured in seven chapters, describing a paper or a series of papers (or talks) where Nambu's originality and genius emerge. Each chapter begins with a historical background section that sets the physics climate of the time, followed by a somewhat detailed discussion of his papers/talks.This tribute to Nambu hopes that he will be remembered and admired for many years to come.
