On conformal supergravity and harmonic superspace [PDF]

open access: yes, 2015
This paper describes a fully covariant approach to harmonic superspace. It is based on the conformal superspace description of conformal supergravity and involves extending the supermanifold M^{4|8} by the tangent bundle of CP^1. The resulting superspace M^{4|8} x TCP^1 can be identified in a certain gauge with the conventional harmonic superspace M^{4|

Dunkl-Poisson Equation and Related Equations in Superspace

open access: yesMathematical Modelling and Analysis, 2015
In this paper, we investigate the Almansi expansion for solutions of Dunkl-polyharmonic equations by the 0-normalized system for the Dunkl-Laplace operator in superspace.

The Binary Invariant Differential Operators on Weighted Densities on the superspace $\mathbb{R}^{1|n}$ and Cohomology [PDF]

open access: yesJOURNAL OF MATHEMATICAL PHYSICS 51, 043504 (2010), 2009
Over the $(1,n)$-dimensional real superspace, $n>1$, we classify $\mathcal{K}(n)$-invariant binary differential operators acting on the superspaces of weighted densities, where $\mathcal{K}(n)$ is the Lie superalgebra of contact vector fields. This result allows us to compute the first differential cohomology of %the Lie superalgebra $\mathcal{K}(n)$

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

open access: yesJournal 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 ...

Exploring curved superspace [PDF]

open access: yesJournal of High Energy Physics, 2012
We systematically analyze Riemannian manifolds M that admit rigid supersymmetry, focusing on four-dimensional N=1 theories with a U(1)_R symmetry. We find that M admits a single supercharge, if and only if it is a Hermitian manifold. The supercharge transforms as a scalar on M.

Cubic interactions for arbitrary spin N $$ \mathcal{N} $$ -extended massless supermultiplets in 4d flat space

open access: yesJournal of High Energy Physics, 2019
N $$ \mathcal{N} $$ -extended massless arbitrary integer and half-integer spin supermultiplets in four dimensional flat space are studied in the framework of light-cone gauge formalism.

The BV Formalization of Chern-Simons Theory on Deformed Superspace [PDF]

open access: yesComm. Theor. Phys. 58: 704, 2012, 2012
In this paper we will study non-abelian Chern-Simons theory on a deformed superspace. We will deform the superspace in such a way that it includes the noncommutativity between bosonic and fermionic coordinates. We will first analyse the BRST and the anti-BRST symmetries of the Chern-Simons theory on this deformed superspace.

Near-Horizon Supergravity Superspace [PDF]

open access: yes, 1998
We present a construction of the superspace of maximally supersymmetric adS_{p+2} x S^{d-p-2} near-horizon geometry based entirely on the supergravity constraints of which the bosonic space is a solution. Besides the geometric superfields, i.e.

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

open access: yesSmall 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.
