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.

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 ...

Minkowski superspaces and superstrings as almost real-complex supermanifolds

, 2012
In 1996/7, J. Bernstein observed that smooth or analytic supermanifolds that mathematicians study are real or (almost) complex ones, while Minkowski superspaces are completely different objects. They are what we call almost real-complex supermanifolds, i.

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.

Massive on-shell supersymmetric scattering amplitudes

Journal of High Energy Physics, 2019
We introduce a manifestly little group covariant on-shell superspace for massive particles in four dimensions using the massive spinor helicity formalism.

Double-Spinor Superstrings on Coset Superspaces

, 2008
The double-spinor formalism, proposed by Aisaka and Kazama, provides a basis for the pure-spinor formalism, which allows manifestly super-Poincare covariant quantization of superstrings.

Advanced thermoelectric performance of a textured ceramic composite: Encapsulation of NaxCoO2 into a triple‐phase matrix

Journal of the American Ceramic Society, Volume 107, Issue 12, Page 7951-7965, December 2024.
Abstract Sodium cobaltite (NaxCoO2) is one of the most renowned and thermoelectrically promising p‐type cobalt oxide materials, showing exceptional performance in this domain. Nonetheless, its thermal instability in air renders it unsuitable for high‐temperature applications such as energy harvesting from industrial waste heat.

Distributions and integration in superspace [PDF]

Journal of Mathematical Physics, 2018
Distributions in superspace constitute a very useful tool for establishing an integration theory. In particular, distributions have been used to obtain a suitable extension of the Cauchy formula to superspace and to define integration over the superball and the supersphere through the Heaviside and Dirac distributions, respectively.
