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.

Higher spins in hyper-superspace

Nuclear Physics B, 2015
We extend the results of arXiv:1401.1645 on the generalized conformal Sp(2n)-structure of infinite multiplets of higher-spin fields, formulated in spaces with extra tensorial directions (hyperspaces), to the description of OSp(1|2n)-invariant infinite ...

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.

On Einstein equations on manifolds and supermanifolds

, 2002
The Einstein equations (EE) are certain conditions on the Riemann tensor on the real Minkowski space M. In the twistor picture, after complexification and compactification M becomes the Grassmannian $Gr_{2}^{4}$ of 2-dimensional subspaces in the 4 ...

Bonding Heterogeneity and Nanoprecipitation on Substituting the Anionic Framework in Mg3Sb2 for p‐Type Zintl Thermoelectrics

Small Structures, Volume 6, Issue 4, April 2025.
Alloying‐induced bonding heterogeneity in p‐type Mg3(Sb1−2xBixSnx)2 leads to local atomic ordering, site preferences, and heterogeneous interfaces, influencing structural transitions and thermoelectric properties. A partial trigonal‐to‐monoclinic phase transition occurs, with a cubic Mg2Sn nanophase emerging at higher alloying content.

All Chern-Simons invariants of 4D, N = 1 gauged superform hierarchies

Journal of High Energy Physics, 2017
We give a geometric description of supersymmetric gravity/(non-)abelian p-form hierarchies in superspaces with 4D, N = 1 super-Poincaré invariance. These hierarchies give rise to Chern-Simons-like invariants, such as those of the 5D, N = 1 graviphoton ...

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.

Higher Spins from Tensorial Charges and OSp(N|2n) Symmetry

, 2003
It is shown that the quantization of a superparticle propagating in an N=1, D=4 superspace extended with tensorial coordinates results in an infinite tower of massless spin states satisfying the Vasiliev unfolded equations for free higher spin fields in ...

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
