Query: Non-Abelian statistics in light scattering processes across interacting
  Haldane chains   The $S=1$ Haldane state is constructed from a product of local singlet dimers
in the bulk and topological states at the edges of a chain. It is a fundamental
representative of topological quantum matter. Its well-known representative,
the quasi-one-dimensional SrNi$_2$V$_2$O$_8$ shows both conventional as well as
unconventional magnetic Raman scattering. The former is observed as one- and
two-triplet excitations with small linewidths and energies corresponding to the
Haldane gap $\Delta_H$ and the exchange coupling $J_c$ along the chain,
respectively. Well-defined magnetic quasiparticles are assumed to be stabilized
by interchain interactions and uniaxial single-ion anisotropy. Unconventional
scattering exists as broad continua of scattering with an intensity $I(T)$ that
shows a mixed bosonic / fermionic statistic. Such a mixed statistic has also
been observed in Kitaev spin liquids and could point to a non-Abelian symmetry.
As the ground state in the bulk of SrNi$_2$V$_2$O$_8$ is topologically trivial,
we suggest its fractionalization to be due to light-induced interchain exchange
processes. These processes are supposed to be enhanced due to a proximity to an
Ising ordered state with a quantum critical point. A comparison with
SrCo$_2$V$_2$O$_8$, the $S=1/2$ analogue to our title compound, supports these
statements.
