The linear $\protect \mathfrak{n}(1|N)$–invariant differential operators and $\protect \mathfrak{n}(1|N)$–relative cohomology

Comptes Rendus. Mathématique, 2020
Over the $(1,N)$-dimensional supercircle $S^{1|N}$, we classify $\mathfrak{n}(1|N)$-invariant linear differential operators acting on the superspaces of weighted densities on $S^{1|N}$, where $\mathfrak{n}(1|N)$ is the Heisenberg Lie superalgebra.

Covariant Differential Calculi on $SP_q^{1|2}$

, 2016
A unitary orthosymplectic quantum supergroup is introduced. Two covariant differential calculi on the quantum superspace $SP_q^{1|2}$ are presented. The $h$-deformed symplectic superspaces via a contraction of the $q$-deformed symplectic superspaces are ...

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.

Pauli-Lubanski, supertwistors, and the superspinning particle

Journal of High Energy Physics, 2017
We present a novel construction of the super-Pauli-Lubanski pseudo-vector for 4D supersymmetry and show how it arises naturally from the spin-shell constraints in the supertwistor formulation of superparticle dynamics.

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 ...

Dichotomy and H^infinity functional calculi

Electronic Journal of Differential Equations, 1995
densely defined closed operator on a Banach space is studied. We give conditions under which an operator with an $H^infty$ functional calculus has dichotomy.

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 ...

The incommensurate composite YxOs4B4 (x = 1.161)

Acta Crystallographica Section B, Volume 80, Issue 6, Page 724-731, December 2024.
Tetragonal YxOs4B4 (x = 1.161) is an incommensurate composite of columns of Y atoms in a three‐dimensional Os4B4 framework. The structure was refined using the superspace approach.YxOs4B4 (x = 1.161) crystallizes as a tetragonal incommensurate composite of columns of Y atoms extending along [001] in an Os4B4 framework.

Pure spinor superspace action for D = 6, N = 1 super-Yang-Mills theory

Journal of High Energy Physics, 2018
A Batalin-Vilkovisky action for D = 6, N = 1 super-Yang-Mills theory, including coupling to hypermultiplets, is given. The formalism involves pure spinor superfields.

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 ...
