Phase separation and phase transitions in undoped and Rh3+ doped iron pnictide CaFe2As2: a Raman scattering study

V. P. Gnezdilov, A. Yu. Glamazda, P. Lemmens +2

Iron-pnictides Ca(Fe1-xRhx)2As2 (x = 0, 0.035, and 0.19) were studied across the tetragonal-orthorhombic and uncollapsed to collapsed tetragonal phase transitions using Raman spect…

Discrimination of Chiral and Helical Contributions to Raman Scattering of Liquid Crystals using Vortex Beams

Silvia Müllner, Florian Büscher, Angela Möller +1

We use vortex photon fields with orbital and spin angular momentum to probe chiral fluctuations within liquid crystals. In the regime of iridescence with a well-defined pitch lengt…

Thermally populated versus field-induced triplon bound states in the Shastry-Sutherland lattice SrCu(BO)

Dirk Wulferding, Youngsu Choi, Seungyeol Lee +6

The Shastry-Sutherland compound SrCu(BO) constituting orthogonally coupled dimers harbors a singlet ground state. The confluence of strong interdimer interaction…

Raman scattering of plane-wave and twisted light off chiral molecular liquids

Florian Büscher, Silvia Müllner, Dirk Wulferding +5

We present an experimental study of the quasi-elastic Raman scattering (QES) of plane-wave and twisted light by liquid crystals. Depending on their temperature, these crystals can…

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…

Effect of topology on quasi-particle interactions in the Weyl semimetal WP

Dirk Wulferding, Peter Lemmens, Florian Büscher +3

We compare two crystallographic phases of the low-dimensional WP to better understand features of electron-electron and electron-phonon interactions in topological systems. The…
