Solution-processed and thermally annealed thin films from a series of nalkyl terminated anilino squaraines are systematically investigated regarding their structural and optical properties by means of X-ray diffraction (XRD) and spectroscopic ellipso

This paper reports reports on the spin-orbit exciton and its crystal-field splitting in $\ensuremath{\alpha}$-RuCl${}_{3}$, as observed in Raman and infrared spectroscopy and show the onset of a j=1/2 scenario and signatures of dominant Kitaev exchan

Raman and terahertz spectroscopy, combined with exact diagonalization studies, reveal the nature of the high-field phase of the proximate Kitaev material $\ensuremath{\alpha}$-RuCl${}_{3}$ as a partially polarized quantum disordered state. The state

In the quest for realizations of quantum spin liquids, the exploration of Kitaev materials - spin-orbit entangled Mott insulators with strong bond-directional exchanges - has taken center stage. However, in these materials the local spin-orbital j=1/

Phase-change materials are employed as active elements in optical and electronic memory devices. Upon crystallization, their visible and near-infrared dielectric properties change dramatically due to the formation of resonant bonds, a unique type of

We establish the double perovskite Ba2CeIrO6 as a nearly ideal model system for j = 1/2 moments, with resonant inelastic x-ray scattering indicating that the ideal j = 1/2 state contributes by more ...

The bulk electronic properties of compensated topological insulators are strongly affected by the self-organized formation of charge puddles at low temperature, but their response in the microwave frequency range is little studied. We employed broadb

The peculiar surface transport properties of topological insulators often require tuning of the Fermi level close to the Dirac point. This, however, reduces the screening capabilities of the Dirac-like surface carriers and thus enhances the sensitivi
