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…
Crystal field splitting in SrIrO ( = 1, 2) iridates probed by x-ray Raman spectroscopy
M. Moretti Sala, M. Rossi, A. Al-Zein +9
Non-resonant Raman spectroscopy in the hard X-ray regime has been used to explore the electronic structure of the first two members of the Ruddlesden-Popper series SrIr…
Temperature dependence of crystal field excitations in CuO
Simo Huotari, Laura Simonelli, Christoph J. Sahle +3
We report a study on the temperature dependence of the charge-neutral crystal field (dd) excitations in cupric oxide, using nonresonant inelastic x-ray scattering (IXS) spectroscop…
Resonant X-ray scattering and the electronic ground state in iridate perovskites
M. Moretti Sala, S. Boseggia, D. F. McMorrow +1
The resonant X-ray scattering (magnetic elastic, RXMS, and inelastic, RIXS) of Ir at the L edges relevant to spin-orbit Mott insulators AIrO (…
Compressed correlation functions and fast aging dynamics in metallic glasses
B. Ruta, G. Baldi, G. Monaco +1
We present x-ray photon correlation spectroscopy measurements of the atomic dynamics in a Zr67Ni33 metallic glass, well below its glass transition temperature. We find that the dec…
Atomic-scale relaxation dynamics and aging in a metallic glass probed by X-ray photon correlation spectroscopy
B. Ruta, Y. Chushkin, G. Monaco +5
We use X-Ray Photon Correlation Spectroscopy to investigate the structural relaxation process in a metallic glass on the atomic length scale. We report evidence for a dynamical cro…
Glass-specific behavior in the damping of acoustic-like vibrations
B. Rufflé, G. Guimbretière, E. Courtens +2
High frequency sound is observed in lithium diborate glass, LiO--2BO, using Brillouin scattering of light and x-rays. The sound attenuation exhibits a non-trivial depen…
Observation of the onset of strong scattering on high frequency acoustic phonons in densified silica glass
B. Ruffle, M. Foret, E. Courtens +2
The linewidth of longitudinal acoustic waves in densified silica glass is obtained by inelastic x-ray scattering. It increases with a high power alpha of the frequency up to a cros…
Relaxation processes in harmonic glasses?
G. Ruocco, F. Sette, R. Di Leonardo +4
A relaxation process, with the associated phenomenology of sound attenuation and sound velocity dispersion, is found in a simulated harmonic Lennard-Jones glass. We propose to iden…
