T-duality in (2, 1) superspace [PDF]

Journal of High Energy Physics, 2019
Abstract We find the T-duality transformation rules for 2-dimensional (2,1) supersymmetric sigma-models in (2,1) superspace. Our results clarify certain aspects of the (2,1) sigma model geometry relevant to the discussion of T-duality.

Double Copy From Tensor Products of Metric BV■‐Algebras

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.

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.

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.

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

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.

Supersymmetric string model with 30 kappa--symmetries in an extended D=11 superspace and 30/ 32 BPS states

, 2003
A supersymmetric string model in the D=11 superspace maximally extended by antisymmetric tensor bosonic coordinates, $\Sigma^{(528|32)}$, is proposed. It possesses 30 $\kappa$-symmetries and 32 target space supersymmetries.

Giant Topological Hall Effect and Colossal Magnetoresistance in Heusler Ferromagnet near Room Temperature

Advanced Materials, Volume 37, Issue 3, January 22, 2025.
Ferromagnetic shape memory Heusler alloy Ni2Mn1.4In0.6 exhibits colossal magnetoresistance (CMR) and giant topological Hall effect (THE) near room temperature, which is attributed to the enhanced spin chirality emerging from the formation of domains and domain walls, which in turn resulted from the combined effect of magnetic field induced martensite ...
