Modulation of the modulated magnetic structure of an Ho i‐MAX phase described by a magnetic (3+2)‐dimensional superspace group

Acta Crystallographica Section B, Volume 81, Issue 1, Page 37-46, February 2025.
A rare complex incommensurate magnetic structure, an amplitude‐modulated structure which itself is modulated, was determined in the Ho‐based i‐MAX phase (Mo2/3Ho1/3)2GaC. It represents a particularly distinctive case of a 2‐k magnetic structure with no symmetry relation between the propagation vectors.The magnetic structures of the Ho‐based i‐MAX phase

Near horizon superspace [PDF]

Journal of High Energy Physics, 1998
The adS_{p+2} x S^{d-p-2} geometry of the near horizon branes is promoted to a supergeometry: the solution of the supergravity constraints for the vielbein, connection and form superfields are found. This supergeometry can be used for the construction of new superconformal theories.

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.

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 ...

Superfield realization of hidden R-symmetry in extended supersymmetric gauge theories and its applications

Journal of High Energy Physics, 2020
We present the explicit superfield realizations of the hidden SU(4) and O(5) R-symmetries in 4D, N $$ \mathcal{N} $$ = 4 and 5D, N $$ \mathcal{N} $$ = 2 supersymmetric Yang-Mills theories in the harmonic superspace approach.

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.

High‐performance thermoelectric calcium cobaltite nanoribbon ceramic via electrospinning and dual spark plasma texturing

Journal of the American Ceramic Society, Volume 108, Issue 2, February 2025.
Abstract High‐performance polycrystalline calcium cobaltite ceramic was synthesized via electrospinning of nanoribbons, followed by dual‐process compaction using spark plasma sintering and edge‐free spark plasma texturing. The combination of nanoribbon electrospinning and this multistage sintering technique was employed for the first time and resulted ...

Advances in Texturing and Thermoelectric Properties of a Calcium Cobaltite Ceramic via Combined Spark Plasma Sintering and Spark Plasma Texturing

Advanced Functional Materials, Volume 35, Issue 1, January 2, 2025.
Calcium cobaltite [Ca2CoO3‐δ]0.62[CoO2] emerges as a promising p‐type thermoelectric material suitable for high‐temperature applications in the air. Employing a combination of spark plasma sintering and edge‐free spark plasma texturing, a highly textured polycrystalline ceramic is successfully fabricated.

Jack Polynomials in Superspace [PDF]

Communications in Mathematical Physics, 2003
This work initiates the study of {\it orthogonal} symmetric polynomials in superspace. Here we present two approaches leading to a family of orthogonal polynomials in superspace that generalize the Jack polynomials. The first approach relies on previous work by the authors in which eigenfunctions of the supersymmetric extension of the trigonometric ...
