Showing papers on "Superspace published in 1980"


Journal ArticleDOI
Abstract: A mathematically rigorous definition of a global supermanifold is given. This forms an appropriate model for a global version of superspace, and a class of functions is defined which corresponds to superfields. This new construction is compared with several pre‐existing definitions of supermanifold and graded manifold; it is shown to include all these definitions and to go beyond them, particularly in admitting the possibility of nontrivial topology in the anticommuting sector. Local differential geometry and potential applications to supergravity are considered.

TL;DR: In this paper, a self-contained superfield approach to global supersymmetry in anti-de Sitter space (OSp(1,4)) is developed, and the reducibility questions are analyzed, focusing in particular on the structure of chiral representations of OSp(4).
Abstract: A self-contained superfield approach to global supersymmetry in anti-de Sitter space (OSp(1,4)) is developed. General transformation laws for OSp(1,4) superfields are established, and all basic elements of the OSp(1,4)-covariant formalism, such as covariant superfield derivatives, invariant integration measures over the superspace OSp(1,4)/O(1,3) in both the real and shifted bases, relations between different parametrisations of superspace, etc., are given explicitly. The reducibility questions are analysed, focusing in particular on the structure of chiral representations of OSp(1,4). The simplest linear OSp(1,4)-invariant models are constructed: the OSp(1,4) analogue of the Wess-Zumino model and OSp(1,4) extension of the Yang-Mills theory. The first model, together with the spontaneous breaking of OSp(1,4), exhibits an effect of the spontaneous violation of P and CP parties with the strength related to the anti-de Sitter radius. The relation of the proposed approach to supergravity is discussed.

TL;DR: In this article, various types of degeneracy lifting, related to different forms of the Lifschitz invariants, which can arise in the energy dispersion curve, and determine the possible onset of one or several incommensurate phases.
Abstract: We investigate the various types of degeneracy lifting, related to different forms of the Lifschitz invariants, which can arise in the energy dispersion curve, and determine the possible onset of one or several incommensurate phases. Necessary symmetry conditions are indicated for the occurence of “conical” points which correspond to an isotropic k dependence in a plane. Various types of these points are distinguished, and it is pointed out that conical points, which occur in the tetragonal, trigonal, and hexagonal space groups, are associated to modulated phases having lower superspace symmetries than when the modulation is along the third fourth, or sixth order axis.
