Gauge-dependent topology in non-reciprocal hopping systems with pseudo-Hermitian symmetry

open access: yesCommunications Physics, 2021
Non-Hermitian physics, an active topic in photonics, is also being increasingly extended to investigate the band topologies of condensed-matter systems.

Rings of quotients of topological rings

open access: yesMathematische Annalen, 1969
This paper is concerned primarily with the question of extending the topology of a topological ring to its complete ring of quotients so that the given ring is an open subring of the quotient ring. This type of problem was considered in a very special case by Warner [6]. General topological embeddings have been studied by End6 [1]. Both of these papers

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

open access: yesAdvanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Topological polaritons in natural uniaxial materials

open access: yesNature Communications
Surface polaritons in natural materials offer unique opportunities for tailoring light–matter interactions at the nanoscale. While various classes of surface polaritons have recently been unveiled via near-field imaging techniques, their connection to ...

Endless Dirac nodal lines in kagome-metal Ni3In2S2

open access: yesnpj Computational Materials, 2022
Topological semimetals are a frontier of quantum materials. In multiband electronic systems, topological band crossings can form closed curves, known as nodal lines.

Topological insights from the Chinese Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 2001
L. Kauffman conjectured that a particular solution of the Chinese Rings puzzle is the simplest possible. We prove his conjecture by using low-dimensional topology and group theory. We notice also a surprising connection between the Chinese Rings and Habiro moves (related to Vassiliev invariants).

Mitigating Creep Anisotropy and Enhancing Performance in Additively Manufactured Ni‐Based Superalloys: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

A note on rings of continous functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
For a topological space X, and a topological ring A, let C(X,A) be the ring of all continuous functions from X into A under the pointwise multiplication.
