On almost \(s-\)topological vector spaces

Journal of Advanced Studies in Topology, 2018
In this paper, we introduce the notion of almost \(s-\)topological vector spaces and present some examples and counterexamples of almost \(s-\)topological vector spaces. Some general properties of almost \(s-\)topological vector spaces are investigated.

Bounded sets in topological vector spaces [PDF]

Mathematische Annalen, 1996
We study the relationship between the collection of bounded subsets of a metrizable topological vector space and various orderings on \(\mathbb{N}^{\mathbb{N}}\) related to the ordering of eventual dominance. This leads to a characterization of normability in metrizable topological vector sapces of large density in terms of the density of their bounded

Symmetry Enhanced Unconventional Spin Current Anisotropy in a Collinear Antiferromagnet

Advanced Functional Materials, EarlyView.
Spin‐orbit torques (SOTs) are investigated in epitaxial FeSn, a topological antiferromagnet with kagome lattice symmetry. Combining experimental and theoretical approaches, the study identifies a six‐fold conventional damping‐like spin‐orbit torque (DL SOT), along with the coexistence of both six‐fold and uniaxial unconventional field‐like torque (FL ...

Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals

Advanced Functional Materials, EarlyView.
In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

Sequential convergence in topological vector spaces

Topology and its Applications, 2000
\(E\) est un espace vectoriel localement convexe et séparé sur \(R\) où \(C\), et \(\tau\) sa topologie. Les AA. demontrent l'équivalence des propriétés suivantes: (i) \(\tau\) est la plus fine des topologies admettant les mêmes suites convergeant vers 0 (on dit, alors, que \(F\) est séquentiellement maximal); (ii) est continue toute application ...

2D Borophene: In‐Plane Hyperbolic Polaritons in the Visible Spectral Range

Advanced Functional Materials, EarlyView.
Researchers have synthesized the χ3 phase of borophene, a 2D metal, using chemical vapor deposition. Combining theory and deep‐subwavelength spectroscopy, they uncover borophene's unique anisotropic optical behavior in the visible range. This breakthrough paves the way for advanced optoelectronic devices using borophene‐based heterostructures ...
