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…
Impact of a monolayer on the nanoscale thermoelastic response of silicon heterostructures
Davide Soranzio, Denny Puntel, Manuel Tuniz +18
Understanding the thermoelastic response of a nanostructure is crucial for the choice of materials and interfaces in electronic devices with improved and tailored transport propert…
Transient grating spectroscopy on a DyCo thin film with femtosecond extreme ultraviolet pulses
Victor Ukleev, Ludmila Leroy, Riccardo Mincigrucci +11
Surface acoustic waves (SAWs) are excited by femtosecond extreme ultraviolet (EUV) transient gratings (TGs) in a room-temperature ferrimagnetic DyCo alloy. TGs are generated by…
Nanoscale transient polarization gratings
Laura Foglia, Björn Wehinger, Giovanni Perosa +24
We present the generation of transient polarization gratings at the nanoscale, achieved using a tailored accelerator configuration of the FERMI free electron laser. We demonstrate…
Extreme ultraviolet transient gratings: A tool for nanoscale photoacoustics
L. Foglia, R. Mincigrucci, A. A. Maznev +23
Collective lattice dynamics determine essential aspects of condensed matter, such as elastic and thermal properties. These exhibit strong dependence on the length-scale, reflecting…
Effect of intense x-ray free-electron laser transient gratings on the magnetic domain structure of Tm:YIG
Victor Ukleev, Max Burian, Sebastian Gliga +13
Magnetic patterns can be controlled globally using fields or spin polarized currents. In contrast, the local control of the magnetization on the nanometer length scale remains chal…
Ultrafast dynamics in (TaSe)I triggered by valence and core-level excitation
Wibke Bronsch, Manuel Tuniz, Giuseppe Crupi +16
In this work, we study the out-of-equilibrium dynamics of the paradigmatic quasi-one-dimensional material (TaSe)I, that exhibits a transition into an incommensurate CDW pha…
