Magnetic structure determination of multiple phases in the multiferroic candidate GdCrO3

Acta Crystallographica Section B, Volume 81, Issue 3, Page 293-301, June 2025.
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 Superspace Varieties, Superspace Quadrics and Non-Splitting

Documenta Mathematica, 2020
This article is a continuation of a previous article which concerned the splitting problem for subspaces of superspaces. We begin with a general account of projective superspaces. Subsequently, we specialise to subvarieties of "positive" projective superspaces.

Massive on-shell supersymmetric scattering amplitudes

Journal of High Energy Physics, 2019
We introduce a manifestly little group covariant on-shell superspace for massive particles in four dimensions using the massive spinor helicity formalism.

Noncommutative Superspace, Supermatrix and Lowest Landau Level

, 2003
By using graded (super) Lie algebras, we can construct noncommutative superspace on curved homogeneous manifolds. In this paper, we take a flat limit to obtain flat noncommutative superspace.

Quantum Klein Space and Superspace [PDF]

, 2018
We give an algebraic quantization, in the sense of quantum groups, of the complex Minkowski space, and we examine the real forms corresponding to the signatures $(3,1)$, $(2,2)$, $(4,0)$, constructing the corresponding quantum metrics and providing an ...

Integration of Grassmann variables over invariant functions on flat superspaces [PDF]

, 2008
We study integration over functions on superspaces. These functions are invariant under a transformation which maps the whole superspace onto the part of the superspace which only comprises purely commuting variables.

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 $\mathbb{P}^n$.

Non-uniqueness of the supersymmetric extension of the O(3) σ-model

Journal of High Energy Physics, 2017
We study the supersymmetric extensions of the O(3) σ-model in 1+1 and 2+1 dimensions. We show that it is possible to construct non-equivalent supersymmetric versions of a given model sharing the same bosonic sector and free from higher-derivative terms.

Correlation functions of spinor current multiplets in N $$ \mathcal{N} $$ = 1 superconformal theory

Journal of High Energy Physics, 2021
We consider N $$ \mathcal{N} $$ = 1 superconformal field theories in four dimensions possessing an additional conserved spinor current multiplet S α and study three-point functions involving such an operator.
