Equivalence of superspace groups [PDF]
Acta Crystallographica Section A Foundations of Crystallography, 2012 An algorithm is presented which determines the equivalence of two settings of a (3 + d)-dimensional superspace group (d = 1, 2, 3). The algorithm has been implemented as a web tool findssg on SSG(3+d)D, providing the transformation of any user-given superspace group to the standard setting of this superspace group in SSG(3+d)D.

Riemannian symmetric superspaces and their origin in random‐matrix theory [PDF]
, 1996 Gaussian random‐matrix ensembles defined over the tangent spaces of the large families of Cartan’s symmetric spaces are considered. Such ensembles play a central role in mesoscopic physics, as they describe the universal ergodic limit of disordered and ...

DUALITY OF THE SUPERSTRING IN SUPERSPACE
Modern Physics Letters A, 1994 The evolution of a closed NSR string is considered in the background of constant graviton and antisymmetric fields. The σ-model action is written in a manifestly supersymmetric form in terms of superfields. The first order formalism adopted for the closed bosonic string is generalized to implement duality transformations and the constant dual ...

Circumnavigating collinear superspace [PDF]
Journal of High Energy Physics, 2020 AbstractIn this paper, we extend the collinear superspace formalism to include the full range of$$ \mathcal{N} $$N= 1 supersymmetric interactions. Building on the effective field theory rules developed in a companion paper —Navigating Collinear Superspace[1] — we construct collinear superspace Lagrangians for theories with non-trivialF- andD-term ...

Superalgebra cohomology, the geometry of extended superspaces and superbranes [PDF]
, 2001 We present here a cohomological analysis of the new spacetime superalgebras that arise in the context of superbrane theory. They lead to enlarged superspaces that allow us to write D-brane actions in terms of fields associated with the additional ...

$ N = \frac{1}{2} $ deformations of chiral superspaces from new quantum Poincaré and Euclidean superalgebras [PDF]
, 2011 A bstractWe present a large class of supersymmetric classical r-matrices, describing the supertwist deformations of Poincaré and Euclidean superalgebras.

Journal of High Energy Physics, 2021 We explicitly compute the component action of certain recently discovered new N $$ \mathcal{N} $$ = 1 supergravity actions which enlarge the space of scalar potentials allowed by supersymmetry and also contain fermionic interaction terms that become ...

Superbranes, D=11 CJS supergravity and enlarged superspace coordinates/fields correspondence
, 2005 We discuss the r\^ole of enlarged superspaces in two seemingly different contexts, the structure of the $p$-brane actions and that of the Cremmer-Julia-Scherk eleven-dimensional supergravity.

Harmonic Superspaces and Superconformal Fields [PDF]
, 2000 Representations of four-dimensional superconformal groups on harmonic superfields are discussed. It is argued that any representation can be given as a superfield on many superflag manifolds.
