Non-Abelian statistics in light scattering processes across interacting Haldane chains
Vladimir Gnezdilov, Vladimir Kurnosov, Yurii Pashkevich +6
The 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 topo…

Longitudinal magnon, inversion breaking and magnetic instabilities in the pseudo-Kagome francisites Cu3Bi(SeO3)2O2X with X=Br, Cl
V. Gnezdilov, Yu. Pashkevich, V. Kurnosov +6
We performed Raman studies and a dielectric characterization of the pseudo-kagome Cu3Bi(SeO3)2O2X (X = Cl, Br). These compounds share competing nearest-neighbour ferromagnetic exch…
