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.

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.

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.

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 ...

All (4,0): Sigma models with (4,0) off-shell supersymmetry

Journal of High Energy Physics, 2017
Off-shell (4, 0) supermultiplets in 2-dimensions are formulated. These are used to construct sigma models whose target spaces are vector bundles over manifolds that are hyperkähler with torsion.

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.

On AdS4 superspace and supergravity

Journal of High Energy Physics
In the N = 1 superspace, AdS4 supersymmetry is realized as the non-linear super coordinate transformations. The fermionic coordinates form a faithful non-linear representation of supersymmetry on their own.
