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.

Twist-deformed supersymmetries in non-anticommutative superspaces
, 2005 We consider a quantum group interpretation of the non-anticommutative deformations in Euclidean supersymmetric theories. Twist deformations in the corresponding superspaces and supergroups are constructed in terms of the left supersymmetry generators ...

Distributions and integration in superspace [PDF]
Journal of Mathematical Physics, 2018 Distributions in superspace constitute a very useful tool for establishing an integration theory. In particular, distributions have been used to obtain a suitable extension of the Cauchy formula to superspace and to define integration over the superball and the supersphere through the Heaviside and Dirac distributions, respectively.

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.

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.

Advanced Engineering Materials, Volume 27, Issue 17, September 2025.Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.

The quantum chiral Minkowski and conformal superspaces
, 2011 We give a quantum deformation of the chiral super Minkowski space in four dimensions as the big cell inside a quantum super Grassmannian. The quantization is performed in such way that the actions of the Poincare and conformal quantum supergroups on the ...

The Sigma Model on Complex Projective Superspaces [PDF]
, 2009 The sigma model on projective superspaces CP^{S-1|S} gives rise to a continuous family of interacting 2D conformal field theories which are parametrized by the curvature radius R and the theta angle theta.

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.
