The topology of line nodes Band structure degeneracies in topological materials can take the form of lines or even chains of interconnected loops. Wu et al. study theoretically these nodal lines and how they evolve as the system parameters are varied. They focus on a class of materials that have weak spin-orbit coupling and that respect a combination of inversion- and time-reversal symmetry. Noncommutative topological charges are associated with nodal lines in such materials that place… Expand
Ferromagnetic helical nodal line and Kane-Mele spin-orbit coupling in kagome metal Fe3Sn2
The two-dimensional kagome lattice hosts Dirac fermions at its Brillouin zone corners K and K’, analogous to the honeycomb lattice. In the density functional theory electronic structure ofExpand

A recent study showed that the topological nature of nodal lines in a three-band system can be described by the non-Abelian topological charges. The new topological invariants are now one of the keyExpand
$N$-band Hopf insulator
We study the generalization of the three-dimensional two-band Hopf insulator to the case of many bands, where all the bands are separated from each other by band gaps. The obtained Z classificationExpand

Experimental observation of non-Abelian topological charges and edge states.
This work opens the door towards characterization and manipulation of non-Abelian topological charges, which may lead to interesting observables such as trajectory-dependent Dirac/Weyl node collisions in two-dimensional systems, admissible nodal line configurations in three dimensions, and may provide insight into certain strongly correlated phases of twisted bilayer graphene.

From triple-point materials to multiband nodal links
We study a class of topological materials which in their momentum-space band structure exhibit threefold degeneracies known as triple points. Focusing specifically onExpand
Intrinsic in-plane nodal chain and generalized quaternion charge protected nodal link in photonics
This work proposes and demonstrates an in-plane nodal chain in photonics, where all chained nodal lines coexist in a single mirror plane instead of two orthogonal ones. Expand
Manipulation and braiding of Weyl nodes using symmetry-constrained phase transitions
Weyl semimetals are arguably the most paradigmatic form of a gapless topological phase. While the stability of Weyl nodes, as quantified by their topological charge, has been extensivelyExpand
Mild reductive rearrangement of oximes and oxime ethers to secondary amines with hydrosilanes catalyzed by B(C6F5)3
Oximes, its ether derivatives and the corresponding hydroxylamines rearrange to secondary amines when reacted with PhSiH3 and B(C6F5)3 as catalyst. Computations suggest a reduction–rearrangement toExpand

Non-Abelian Reciprocal Braiding of Weyl Nodes
We illustrate a procedure that defines and converts non-Abelian charges of Weyl nodes via braid phase factors, which arise upon exchange inside the reciprocal momentum space. This phenomenon derivesExpand
Strain-engineering Mott-insulating La2CuO4
It is demonstrated that the compressive strain to La2CuO4 films enhances the Coulomb and magnetic-exchange interactions relevant for superconductivity, providing a strategy to optimise the parent Mott state forsuperconductivity. Expand
Supplementary Data for “Non-Abelian band topology in noninteracting metals”
Electron energy bands, which are studied to explain electronic and optical properties of crystalline solids, often exhibit degeneracies called band-structure nodes. Here, we introduce non-AbelianExpand
