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

aff(1|1)-trivial deformations of aff(2|1)-modules of weighted densities on the superspace

Extracta Mathematicae, 2019
Over the (1|2)-dimensional real superspace, we study aff(1|1)-trivial deformations of the action of the affine Lie superalgebra aff(2|1) on the direct sum of the superspaces of weighted densities.

BPS preons and the AdS-M-algebra

, 2008
We present here the AdS generalization of BPS preons, which were introduced as the hypothetical constituents of M-theory preserving all but one supersymmetries.

Magnetic structure determination and refinement using FullProf

Acta Crystallographica Section B, Volume 81, Issue 3, Page 302-317, June 2025.
A description of the FullProf Suite of programs for magnetic structure determination is given. Different types of magnetic structure factors are discussed, and links to examples and tutorials for using the programs are provided.The study of magnetic structures from a crystallographic perspective remains a niche field, largely confined to physical ...

Embedding formalism for AdS superspaces in five dimensions

Journal of High Energy Physics
The standard geometric description of d-dimensional anti-de Sitter (AdS) space is a quadric in ℝ d−1,2 defined by (X 0)2 − (X 1)2 − ⋯ − (X d−1)2 + (X d )2 = ℓ 2 = const.

A codex on linearized Nordström supergravity in eleven and ten dimensional superspaces

Journal of High Energy Physics, 2019
As the full off-shell theories of supergravity in the important dimensions of eleven and ten dimensions are currently unknown, we introduce a superfield formalism as a foundation and experimental laboratory to explore the possibility that the scalar ...

Three-dimensional N=4 supersymmetry in harmonic N=3 superspace

, 2010
We consider the map of three-dimensional N=4 superfields to N=3 harmonic superspace. The left and right representations of the N=4 superconformal group are constructed on N=3 analytic superfields.

Asymmetric structuring of ceramic composite via co‐electrospun sodium cobaltite and calcium cobaltite nanoribbons

Journal of the American Ceramic Society, Volume 108, Issue 5, May 2025.
Abstract An asymmetrically structured sodium cobaltite–calcium cobaltite ceramic composite with enhanced texture was synthesized using co‐electrospinning of nanoribbons and rapid thermal processing (RTP). Long‐term stability tests revealed that embedding the unstable sodium cobaltite in the chemically more stable calcium cobaltite effectively shields ...

Six-dimensional N $$ \mathcal{N} $$ = (2, 0) conformal superspace

Journal of High Energy Physics
We develop a new off-shell formulation for six-dimensional conformal supergravity obtained by gauging the 6D N $$ \mathcal{N} $$ = (2, 0) superconformal algebra in superspace.
