Can the topological frame charges observed in kagome lattice semimetals be formally mapped to the neglecton-induced unitary braiding operations in non-semisimple Ising anyon models?
“Can the topological frame charges observed in kagome lattice semimetals be formally mapped to the neglecton-induced unitary braiding operations in non-semisimple Ising anyon models?”
Inspired by “To what extent can we engineer 'non-semisimple' phases of matter in solid-state devices to experimentally observe the protection of non-Abelian braiding against decoherence?” →Summary
The exploration revealed a categorical distinction between 'topological frame charges' in kagome semimetals and the 'neglecton' framework of non-semisimple Ising anyon models. While frame charges are primarily lattice-geometry and spin-orbit coupling invariants within standard Z2 topological band theory, neglectons are purely algebraic constructs used to bypass the limitations of Clifford-gate Ising anyon TQFTs by utilizing representations with quantum trace zero. No formal mapping exists between these two disparate concepts; the initial hypothesis appears to be a conflation of geometric condensed matter properties with abstract categorical physics.

I am investigating whether the topological frame charges in kagome lattice semimetals can be mapped to the neglecton-induced unitary braiding operations in non-semisimple Ising anyon models. I need to first clarify the nature of 'neglectons' and their role in non-semisimple TQFTs, then look for any existing literature linking these to kagome lattice physics.

Neglectons are new anyon types introduced in non-semisimple TQFTs that allow for universal quantum computation via braiding, overcoming the Clifford-only limitation of standard Ising anyons. They are indexed by a real parameter and operate within an indefinite Hermitian form, with the computational subspace residing in a positive-definite sector.

Current literature on kagome lattice semimetals focuses on Z2 topological classification, spin-orbit coupling, and strain-induced phase transitions. There is no direct evidence or theoretical proposal linking 'topological frame charges' in these materials to the 'neglecton' framework of non-semisimple Ising anyons.

I have confirmed that 'neglectons' are a theoretical construct in non-semisimple TQFTs designed to achieve universal quantum computation with Ising anyons. I need to determine if the 'topological frame charges' in kagome lattice semimetals have any mathematical overlap with the 'negligible' objects that form the basis of neglectons.

Searching for the definition of 'topological frame charges' in condensed matter physics to see if they relate to quantum trace zero representations or non-semisimple categories.

Topological frame charges in kagome systems typically refer to local invariants associated with the lattice geometry and spin-orbit coupling, whereas neglectons are defined by the algebraic structure of non-semisimple TQFTs (specifically representations with quantum trace zero). There is no evidence that these frame charges are equivalent to the neglecton parameter.

The mapping appears to be a category error: frame charges are geometric/lattice-based invariants, while neglectons are algebraic objects in a TQFT framework. I will shift focus to whether non-semisimple TQFTs can be *derived* from kagome lattice models, rather than mapping the charges directly.

The proposed mapping between topological frame charges in kagome lattices and neglecton-induced braiding is unsupported and likely represents a conceptual category error. While both fields utilize topological concepts, their underlying mathematical structures—geometric lattice invariants versus non-semisimple categorical representations—do not currently intersect.
