Measuring the dispersion of spin waves in cuprate superconductors using Resonant Inealstic X-ray Scattering (RIXS) [ESRF & SLS]

We propose several projects on the subject of resonant x-ray spectroscopy, mainly using resonant inelastic x-ray scattering (RIXS) and x-ray absorption spectroscopy (XAS). The experimental activity takes place at the ESRF and SLS synchrotrons, during few days long sessions; the preparation and the work of data analysis and interpretation is done in the Physics Department in Milano.

Here are some possible titles:

Modificatons of the paramagnon spectrum across Tc in underdoped YBCO studied with high resolution RIXS

The effect of stripe order on the phonon dispersion masured by high resolution RIXS

Mesurement by RIXS of the momentum dependent electron-phonon interaction in cuprates

Some information on RIXS of cuprate superconductors can be found in the attached articles.

For the students interested in a thesis project to be fully realized abroad the ESRF proposes every year several opportunities to be complted in 6 months in Grenoble. Here are some recent examples:
