Ultrafast internal dynamics of chiral domain walls probed by time-resolved XRMS
Dmitriy Ksenzov, Flavio Capotondi, Nicolas Jaouen +7
We measure picosecond dynamics of labyrinthine stripe domains with chiral Néel-type domain walls using time-resolved x-ray resonant magnetic scattering (XRMS). At the stripe-domai…
Ultrafast excitation of Bloch plasmon polaritons in hyperbolic metamaterials with an extreme ultra-violet transient grating
Tlek Tapani, Hannes Kempf, Matteo Pancaldi +14
Manipulating materials properties with light drives advances in materials science and photonics. Hyperbolic metamaterials are promising candidates as next-generation quantum optica…
Electronic mechanism of sub-100-fs demagnetization induced by a femtosecond light pulse
Konrad J. Kapcia, Victor Tkachenko, Flavio Capotondi +4
A quantitative understanding of the processes that trigger light-induced demagnetization on ultrashort timescales is crucial for achieving an ultrafast, radiation-controlled magnet…
Single-shot imaging with randomized structured illumination at a free electron laser
Abraham L. Levitan, Kahraman Keskinbora, Matteo Pancaldi +4
Stroboscopic nanoscale imaging with free electron laser light is revolutionizing our understanding of fast dynamics in heterogeneous systems. The short wavelength of X-ray and extr…
Time-domain extreme ultraviolet diffuse scattering spectroscopy of nanoscale surface phonons
F. Capotondi, A. Maznev, F. Bencivenga +18
We report the observation of dynamic fringe patterns in the diffuse scattering of extreme ultraviolet light from surfaces, following femtosecond optical excitation. At each point o…
Soft x-rays with Orbital Angular Momentum for resonant scattering experiments at the SOLEIL synchrotron
Pietro Carrara, Franck Fortuna, Renaud Delaunay +15
The paper presents a comprehensive description of a new setup implemented and commissioned at the SEXTANTS beamline of the SOLEIL synchrotron for absorption and scattering experime…
