"This is the fifth, expanded edition of the comprehensive textbook published in 1990 on the theory and applications of path integrals. It is the first book to explicitly solve path integrals of a wide variety of nontrivial quantum-mechanical systems, in particular the hydrogen atom. The solutions have become possible by two major advances. The first is a new euclidean path integral formula which increases the restricted range of applicability of Feynman's famous formula to include singular attractive 1/r and 1/r[superscript 2] potentials. The second is a simple quantum equivalence principle governing the transformation of euclidean path integrals to spaces with curvature and torsion, which leads to time-sliced path integrals that are manifestly invariant under coordinate transformations." "In addition to the time-sliced definition, the author gives a perturbative definition of path integrals which makes them invariant under coordinate transformations. A consistent implementation of this property leads to an extension of the theory of generalized functions by defining uniquely integrals over products of distributions." "The powerful Feynman-Kleinert variational approach is explained and developed systematically into a variational perturbation theory which, in contrast to ordinary perturbation theory, produces convergent expansions. The convergence is uniform from weak to strong couplings, opening a way to precise approximate evaluations of analytically unsolvable path integrals." "Tunneling processes are treated in detail. The results are used to determine the lifetime of supercurrents, the stability of metastable thermodynamic phases, and the large-order behavior of perturbation expansions. A new variational treatment extends the range of validity of previous tunneling theories from large to small barriers. A corresponding extension of large-order perturbation theory now also applies to small orders." "Special attention is devoted to path integrals with topological restrictions. These are relevant to the understanding of the statistical properties of elementary particles and the entanglement phenomena in polymer physics and biophysics. The Chern-Simons theory of particles with fractional statistics (anyons) is introduced and applied to explain the fractional quantum Hall effect." "The relevance of path integrals to financial markets is discussed, and improvements of the famous Black-Scholes formula for option prices are developed which account for the fact that large market fluctuations occur much more frequently than in Gaussian distributions."--Jacket
Multivalued fields in condensed matter, electromagnetism, and gravitation by Hagen Kleinert( Book )

9 editions published in 2008 in English and Undetermined and held by 161 WorldCat member libraries worldwide

"This book lays the foundations of a theory of fluctuating multivalued fields with numerous applications. Most prominent are phenomena dominated by the statistical mechanics of line-like objects, such as the phase transitions in super-fluids and superconductors, and the melting process of crystals, all being the consequence of a condensation of vortex or defect lines. The phenomenon of charge confinement can also be explained if the electromagnetic potential is a multivalued field which is able lo produce a condensate of magnetic monopoles. There an electric version of the Meissner effect leads to electric flux tubes between charges which bind them permanently together. A third application defines the mathematics of Riemann-Cartan geometry with curvature and torsion and the associated laws of gravity from a new model of spacetime: a world-crystal with translational and rotational defects." "The book provides students.and researchers with supplementary reading material for graduate courses on phase transitions, quantum field theory, gravitational physics, and differential geometry."--Jacket

The Eleventh Marcel Grossmann Meeting : on recent developments in theoretical and experimental general relativity, gravitation and relativistic field theories : proceedings of the MG11 Meeting on General Relativity, Berlin, Germany, 23-29 July 2006 by Marcel Grossmann Meeting on General Relativity( Book )

12 editions published between 2006 and 2008 in English and held by 43 WorldCat member libraries worldwide

The Marcel Grossman Meetings are three-yearly forums that meet to discuss recent advances in gravitation, general relativity and relativistic field theories, emphasizing their mathematical foundations, physical predictions and experimental tests. These meetings aim to facilitate the exchange of ideas among scientists, to deepen our understanding of space-time structures, and to review the status of ongoing experiments and observations testing Einstein's theory of gravitation either from ground or space-based experiments. Since the first meeting in 1975 in Trieste, Italy, which was established by Remo Ruffini and Abdus Salam, the range of topics presented at these meetings has gradually widened to accommodate issues of major scientific interest, and attendance has grown to attract more than 900 participants from over 80 countries. This proceedings volume of the eleventh meeting in the series, held in Berlin in 2006, highlights and records the developments and applications of Einstein's theory in diverse areas ranging from fundamental field theories to particle physics, astrophysics and cosmology, made possible by unprecedented technological developments in experimental and observational techniques from space, ground and underground observatories. It provides a broad sampling of the current work in the field, especially relativistic astrophysics, including many reviews by leading figures in the research community
Particles and quantum fields by Hagen Kleinert( Book )

6 editions published in 2016 in English and held by 42 WorldCat member libraries worldwide

"This book arose from lectures I gave at the Freie Universität Berlin over the past five decades. They were intended to prepare graduate students for their research in elementary-particle physics or in many-body theory of condensed matter. They should serve as a general introduction and a basis for understanding more advanced work on the subject"--Page vii
