Physical Review Research, 2020 Semimetals exhibiting nodal lines or nodal surfaces represent a novel class of topological states of matter. While conventional Weyl semimetals exhibit momentum-space Dirac monopoles, these more exotic semimetals can feature unusual topological defects ...

Three-dimensional Weyl topology in one-dimensional photonic structures
Light: Science & Applications, 2022 Topological features, in particular distinct band intersections known as nodal rings, usually requiring three-dimensional structures, have now been demonstrated experimentally in an elegantly simple one-dimensional photonic crystal.

Signatures of topological phase transitions in mesoscopic superconducting rings
New Journal of Physics, 2013 We investigate Josephson currents in mesoscopic rings with a weak link which are in or near a topological superconducting phase. As a paradigmatic example, we consider the Kitaev model of a spinless p-wave superconductor in one dimension, emphasizing how

Regularity in Topological Modules
Mathematics, 2020 The framework of Functional Analysis is the theory of topological vector spaces over the real or complex field. The natural generalization of these objects are the topological modules over topological rings.

Topological properties of black rings
Nuclear Physics BIn this paper, we study topological properties of neutral and dipole black rings. Different values of the rings' parameters are used to calculate topological numbers.

Topological Charge of Multi-Color Optical Vortices
Photonics, 2022 The topological charge of an optical vortex is a quantity rather stable against phase distortions, for example, turbulence. This makes the topological charge attractive for optical communications, but for many structured beams it is unknown.

Three-dimensional Pentagon Carbon with a genesis of emergent fermions
Nature Communications, 2017 Whether carbon allotropes may host emergent topological fermions is unknown. Here, Zhonget al. predict a three-dimensional carbon allotrope entirely composed of pentagon rings, showing a plethora of topological fermions under strain.

On lambda-rings and topological realization [PDF]
International Journal of Mathematics and Mathematical Sciences, 2005 It is shown that most possibly truncated power series rings admit uncountably many filtered lambda-ring structures. The question of how many of these filtered lambda-ring structures are topologically realizable by the K-theory of torsionfree spaces is also considered for truncated polynomial rings.
