Momentum-space imaging of Cooper pairing in a half-Dirac-gas topological superconductor [PDF]
Nature Physics, 2014 Superconductivity involving topological Dirac electrons has recently been proposed as a platform between concepts in high-energy and condensed-matter physics. It has been predicted that supersymmetry and Majorana fermions, both of which remain elusive in

Topological Signal Processing Over Simplicial Complexes [PDF]
IEEE Transactions on Signal Processing, 2019 The goal of this paper is to establish the fundamental tools to analyze signals defined over a topological space, i.e. a set of points along with a set of neighborhood relations.

Nigh-Open Sets in Topological Space
International Journal of Analysis and Applications, 2023 In this paper, we aim to introduce a new class of open sets namely nigh-open set. Accordingly, we define a topological space called a nigh-topological space. This consequently leads us to outline several new operations in connection with the sets in nigh-

An operation on topological spaces
Applied General Topology, 2000 <p>A (binary) product operation on a topological space X is considered. The only restrictions are that some element e of X is a left and a right identity with respect to this multiplication, and that certain natural continuity requirements are satisfied. The operation is called diagonalization (of X). Two problems are considered: 1.

Ratio Mathematica, 2023 In this article, we explore the idea of door space on -topological space. Here, we discuss which door spaces in this space are related with submaximal. The equivalent conditions shows how it connects a -topological property. Also, we derive various door

All-Si valley-Hall photonic topological insulator [PDF]
Conference on Lasers and Electro-Optics, 2016 An all-Si photonic structure emulating the quantum-valley-Hall effect is proposed. We show that it acts as a photonic topological insulator (PTI), and that an interface between two such PTIs can support edge states that are free from scattering.

On some properties of $T_0$-ordered reflection
Applied General Topology, 2014 In [12], the authors give an explicit construction of the T0−ordered reflection of an ordered topological space (X, τ,≤) . All ordered topological spaces such that whose T0−ordered reflections are T1−ordered spaces are characterized.

Frontiers in Big Data, 2020 A novel subject classification scheme should often be applied to a preclassified bibliographic database for the research evaluation task. Generally, adopting a new subject classification scheme is labor intensive and time consuming, and an effective and ...

A better framework for first countable spaces
Applied General Topology, 2003 In the realm of semiuniform convergence spaces first countability is divisible and leads to a well-behaved topological construct with natural function spaces and one-point extensions such that countable products of quotients are quotients.

On topological spaces of orders
Topology and its Applications, 2009 AbstractWe study the space of linear orders on a given set X, denoted by Op(X), endowed with the topology of pointwise convergence. We show, in particular, that if |X|=ω1 or |X|=ω0 then Op(X) is homeomorphic to 2ω1 and 2ω0, respectively.
