Isometries in anti-de Sitter and Conformal Superspaces [PDF]

JHEP 0007:047,2000, 2000
We derive explicit forms for the superisometries of a wide class of supercoset manifolds, including those with fermionic generators in the stability group. We apply the results to construct the action of SU(2,2|4) on three supercoset manifolds: (10|32)-dimensional AdS_5 x S^5 superspace, (4|16)-dimensional conformal superspace, and a novel (10|16 ...

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.

Teleparallel Superspace in Eleven Dimensions Coupled to Supermembranes [PDF]

Phys.Rev. D65 (2002) 024013, 2001
We present a superspace formulation of N=1 eleven-dimensional supergravity with no manifest local Lorentz covariance, which we call teleparallel superspace. This formulation will be of great importance, when we deal with other supergravity theories in dimensions higher than eleven dimensions, or a possible formulation of noncommutative supergravity. As

Non(anti)commutative N=(1,1/2) Supersymmetric U(1) Gauge Theory

, 2005
We study a reduction of deformation parameters in non(anti)commutative N=2 harmonic superspace to those in non(anti)commutative N=1 superspace. By this reduction we obtain the exact gauge and supersymmetry transformations in the Wess-Zumino gauge of non ...

Membranes and Three-form Supergravity [PDF]

, 1997
We discuss membranes in four-dimensional N=1 superspace. The kappa-invariance of the Green-Schwarz action implies that there is a dual version of N=1 supergravity with a three-form potential.

Magnetic structure determination of multiple phases in the multiferroic candidate GdCrO3

Acta Crystallographica Section B, EarlyView.
Using neutron powder diffraction, the successive magnetic structures in multiferroic candidate GdCrO3 have been determined, including a complex incommensurate phase below 2.3 K. The symmetry analysis uses a combination of little group formalism and superspace group approach highlighting the strength of each method and the results are reported using the

Projective superspaces in practice [PDF]

Journal of Geometry and Physics, 2018
We study the supergeometry of complex projective superspaces $\mathbb{P}^{n|m}$. First, we provide formulas for the cohomology of invertible sheaves of the form $\mathcal{O}_{\mathbb{P}^{n|m}} (\ell)$, that are pull-back of ordinary invertible sheaves on the reduced variety $\mathbb{P}^n$.

Field Theory in Noncommutative Minkowski Superspace

, 2004
There is much discussion of scenarios where the space-time coordinates x^\mu are noncommutative. The discussion has been extended to include nontrivial anticommutation relations among spinor coordinates in superspace.

All (4,0): Sigma models with (4,0) off-shell supersymmetry

Journal of High Energy Physics, 2017
Off-shell (4, 0) supermultiplets in 2-dimensions are formulated. These are used to construct sigma models whose target spaces are vector bundles over manifolds that are hyperkähler with torsion.
