Condensed Matter Physics Seminar: Giulia Fulva Mancini

Abstract: Ultrafast scattering, spectroscopy and imaging are essential tools for understanding and quantifying the functionality of nanoscale systems in space and time domains. The past decades witnessed a revolution in ultrafast pulsed sources, from optical lasers to pulsed X-rays sources.
In the X-ray regime, X-ray Free-Electron Lasers (XFELs) provided intense and coherent X-ray pulses,
enabling to combine novel experimental strategies, based on ultrafast element-selective core-level
spectroscopies and scattering techniques.
In parallel, soft X-ray/EUV light from compact High-Harmonic Generation (HHG) sources have proved
extremely powerful for investigating electronic, structural and magnetic properties in complex
nanostructured systems out-of-equilibrium, with nanometer spatial resolution and pulse durations in
the femtosecond (fs)-to-attosecond (as) range.
In this talk, I will present how EUV light combined with ptychographic Coherent Diffractive Imaging (CDI) across sources enabled revolutionary new hyperspectral, and nano-imaging capabilities, with recent demonstrations in imaging vortex beams carrying orbital angular momentum for X-ray helical dichroism experiments, and ultrafast imaging of charge dynamics.
