Inelastic light scattering in the spin cluster Mott insulator CuOSeO
R. B. Versteeg, C. Boguschewski, P. Becker +1
Clusters of single spins form the relevant spin entities in the formation of long-range magnetic order in spin cluster Mott insulators. Such type of spin order bears resemblance to…

Fingerprints of Kitaev physics in the magnetic excitations of honeycomb iridates
A. Revelli, M. Moretti Sala, G. Monaco +11
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…

A tunable time-resolved spontaneous Raman spectroscopy setup for probing ultrafast collective excitation and quasiparticle dynamics in quantum materials
R. B. Versteeg, J. Zhu, P. Padmanabhan +5
We present a flexible and efficient ultrafast time-resolved spontaneous Raman spectroscopy setup to study collective excitation and quasi-particle dynamics in quantum matter. The s…
