Superunitary Representations of Heisenberg Supergroups

, 2017
Numerous Lie supergroups do not admit superunitary representations except the trivial one, e.g., Heisenberg and orthosymplectic supergroups in mixed signature.

Quaternionic structures, supertwistors and fundamental superspaces [PDF]

, 2016
Superspace is considered as space of parameters of the supercoherent states defining the basis for oscillator-like unitary irreducible representations of the generalized superconformal group SU(2m,2n/2N) in the field of quaternions H.

High‐Entropy Magnetism of Murunskite

Advanced Functional Materials, Volume 35, Issue 40, October 1, 2025.
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

Three-form multiplet and supersymmetry breaking

Journal of High Energy Physics, 2017
Recently, a nilpotent real scalar superfield V was introduced in [1] as a model for the Goldstino. It contains only two independent component fields, the Goldstino and the auxiliary D-field.

The linear $\protect \mathfrak{n}(1|N)$–invariant differential operators and $\protect \mathfrak{n}(1|N)$–relative cohomology

Comptes Rendus. Mathématique, 2020
Over the $(1,N)$-dimensional supercircle $S^{1|N}$, we classify $\mathfrak{n}(1|N)$-invariant linear differential operators acting on the superspaces of weighted densities on $S^{1|N}$, where $\mathfrak{n}(1|N)$ is the Heisenberg Lie superalgebra.

Topics in 3D N=2 AdS supergravity in superspace

, 2012
We review some recent results on the construction in superspace of 3D N=2 AdS supergravities and on the formulation of rigid supersymmetric theories in (1,1) and (2,0) AdS superspaces.Comment: 6 pages, Contribution to the proceedings of the "XVII ...

MagStREXS, a crystallographic computer program to determine magnetic structures through resonant elastic X‐ray scattering data. I. Fundamental equations

Journal of Applied Crystallography, Volume 58, Issue 5, Page 1688-1699, October 2025.
This article presents the fundamental concepts and equations implemented in the program MagStREXS to determine magnetic structures based on resonant elastic X‐ray scattering diffraction data.Resonant elastic X‐ray scattering (REXS) is an experimental technique that can be highly valuable for studying magnetic structures in certain scenarios.

Supersymmetric Born-Infeld actions and new Fayet-Iliopoulos terms

Journal of High Energy Physics, 2019
We consider N $$ \mathcal{N} $$ = 1 supersymmetric Born-Infeld actions that have a second non-linear supersymmetry. We focus on the model proposed by Bagger and Galperin and show that the breaking of the second supersymmetry is sourced by the new Fayet ...

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.
