Low‐Symmetry Weyl Semimetals: A Path to Ideal Topological States
Advanced Functional Materials, EarlyView.This study presents a theoretical framework for realizing ideal Weyl semimetals, where Weyl nodes are well‐isolated at the Fermi level. The approach is exemplified in the low‐symmetry material Cu2SnSe3, which exhibits tunable topological phases, current‐induced orbital magnetization, and a strong circular photogalvanic effect, making it a promising ...

The Fundamental Group of a Group Acting on a Topological Space
ACI Avances en Ciencias e Ingenierías, 2014 In 1966, F. Rhodes introduced the idea of the fundamental group of a group acting on a topological space. His article contains summarized proofs of results and has been studied since then primarily because the category of transformation groups is more ...

Advanced Functional Materials, EarlyView.In this work, Bi2Te3 is integrated into a 3D‐printed nanocarbon electrode for NH4+ storage. A rocking‐chair battery with CuHCF as the cathode delivers a high energy density of 134.8 Wh kg−1 and a power density of 1800 W kg−1. The design allows easy recovery of carbon additives, promoting sustainability and recyclability in next‐generation aqueous ...

Pseudocompact topological group refinements of maximal weight
, 2002 It is known that a compact metrizable group admits no proper pseudocompact topological group refinement. The authors show, in contrast, that every (Hausdorff) pseudocompact Abelian group G = (G, T) of uncountable weight α, satisfying any of the following

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 ...

A Note on the Topological Group c0
Axioms, 2018 A well-known result of Ferri and Galindo asserts that the topological group c 0 is not reflexively representable and the algebra WAP ( c 0 ) of weakly almost periodic functions does not separate points and closed subsets.

On epimorphisms of topological groups
General Topology and its Applications, 1978 AbstractA complete survey of results on the epimorphism problem for various categories of topological groups is given. All known partial results on the epimorphism problem for Hausdorff topological groups support the conjecture that epimorphisms of Hausdorff topological groups have dense image.
