TL;DR: In this paper, various approaches used nowadays in order to understand the structure of the ground state of the strong interaction theory, the so-called QCD vacuum, are reviewed, including semiclassical methods, numerical methods, and macroscopic approaches.

TL;DR: In this article, the present status of the statistical mechanical theory of equilibrium crystal shapes is reviewed, with special emphasis on the relation between singularities occurring in the shapes of three-dimensional (d ǫ 3) crystals and the phase transitions of certain dǫ 2 models.

TL;DR: A detailed description of the methods available for a derivation of a band structure from angle resolved photoemission spectra is given using copper as an example in this article, where data from various sources are collected and reviewed critically in order to derive an experimental band structure for copper.

TL;DR: In this paper, the instanton-based method for calculating the exact Gell-Mann-Low function and bifermionic condensates is described, and a detailed discussion of the supersymmetric O(3) sigma model is provided.

TL;DR: In this paper, a mathematical model of the cochlear mechanics is presented, based on the results of physical measurements of the mechanics of cochlea (inner ear), and the simplest possible solution, a one-dimensional model, is worked out in considerable detail.

TL;DR: In this article, the authors survey the results of those model calculations of the early evolution of single stars that have been obtained over approximately the last decade, and compare some of these results with the observations, concentrating particularly on the comparison between theoretical predictions regarding surface abundances of red giants and Cepheids and abundance estimates obtained by spectral data.

TL;DR: The interpretation problems that appeared at the time of the Bohr-Einstein debate and that were solved only partly or not at all still remain real problems today as mentioned in this paper, despite the considerable successes of present day theoretical and particle physics have greatly increased both the generality of the relativistic quantum physics formalism and confidence in that theory.

TL;DR: In this paper, a systematic analysis of experimental data on fusion and capture of heavy ions above the barrier over a wide mass and energy range is performed within the surface friction model, which allows for independent and different (quadrupole) deformations for projectile and target, the corresponding dissipative forces and statistical fluctuations in all variables.

TL;DR: The status of experimental tests of general relativity to the end of 1983 is reviewed in this paper, including the classical tests, tests of the strong equivalence principle and others, and the possibility of using gravitational-wave observations to test metric theories is discussed.

TL;DR: In this paper, the derivation of dispersion relations is reviewed as well as the intermediate state analysis of Feynman diagrams in terms of Goldstone diagrams at finite temperatures, and applications to magnetic impurities, local two-level systems, intermediate valence models are given.

TL;DR: In this article, the role of the second-order Born term and the physical content of this term and methods for its calculation are discussed in detail, as well as its physical properties.

TL;DR: Experimental evidence and theoretical concepts for the equilibration of the neutron-toproton ratio, N Z, of the fragments from binary dissipative heavy-ion collisions are reviewed in this paper.

TL;DR: In this article, a review of low to moderate frequency magnetic excitations, termed magnons or spin waves, in magnetically ordered materials is presented, focusing on intuitive behavior rather than analytical theory.

TL;DR: The PETRA (Positron-Electron T andem Ring Accelerator) is located at DESY in Hamburg, Germany, and is the highest energy electron-positron storage ring in the world as discussed by the authors.

TL;DR: In this paper, the main emphasis is put on light ion breakup at nonrelativistic energies, and the post-and prior-form DWBA theories are discussed, appropriate for the “spectator breakup” describes elastic as well as inelastic breakup modes.

TL;DR: A detailed account of recent progress in the U(1) problem from the point of view of the anomalous Ward identities and the large N c expansion is given in this paper.
