Order/Disorder Dynamics in a Dodecanethiol-Capped Gold Nanoparticles Supracrystal by Small-Angle Ultrafast Electron Diffraction

Francesco Stellacci, Fabrizio Carbone, Giulia Fulvia Mancini, Javier Reguera Gomez, Tatiana Latychevskaia, Francesco Pennacchio

The design and the characterization of functionalized gold nanoparticles supracrystals require atomically resolved information on both the metallic core and the external organic ligand shell. At present, there is no known approach to characterize simultane ...

Melting of a skyrmion lattice to a skyrmion liquid via a hexatic phase

Henrik Moodysson Rønnow, Arnaud Magrez, Fabrizio Carbone, Marco Cantoni, Ping Huang, Thomas Schönenberger

While in 3D materials melting is a single, first-order phase transition, in 2D systems, it can also proceed via an intermediate phase. For a skyrmion lattice in Cu2OSeO3, magnetic field variations can tune this quasiparticle 2D solid into a skyrmion liquid ...

Ultrafast atomic-scale visualization of acoustic phonons generated by optically excited quantum dots

Fabrizio Carbone, Giovanni Maria Vanacore

Understanding the dynamics of atomic vibrations confined in quasi-zero dimen- sional systems is crucial from both a fundamental point-of-view and a technologi- cal perspective. Using ultrafast electron diffraction, we monitored the lattice dynamics of GaAs ...

Direct Visualisation of Skyrmion Lattice Defect Alignment at Grain Boundaries

Lawrence Daniel Brun, Henrik Moodysson Rønnow, Arnaud Magrez, Fabrizio Carbone, Thomas Schönenberger

We present a method to directly visualise a statistical analysis of skyrmion defect alignment at grain boundaries in the skyrmion host Cu2OSeO3. Using Lorentz transmission electron microscopy, we collected large data sets with several hundreds of frames co ...

Local photo-mechanical stiffness revealed in gold nanoparticles supracrystals by ultrafast small-angle electron diffraction

Francesco Stellacci, Fabrizio Carbone, Giulia Fulvia Mancini, Tatiana Latychevskaia, Francesco Pennacchio, Javier Reguera Gomez

We demonstrate that highly ordered two-dimensional crystals of ligand-capped gold nanoparticles display a local photo-mechanical stiffness as high as that of solids such as graphite. In out-of-equilibrium electron diffraction experiments, a strong temperat ...

Investigating pairing interactions with coherent charge fluctuation spectroscopy

Majed Chergui, Fabrizio Carbone, Andreas Helmut Christian Mann, Ahmad Odeh

It has been recently demonstrated that a pump pulse can generate coherent charge fluctuations in a superconductor through a stimulated Raman process [Mansart, et al., Proc. Natl. Acad. Sci. USA 110, 4539 (2013)]. Here, we present a tutorial review of the b ...

Ultrafast structural and electronic dynamics of the metallic phase in a layered manganite

Fabrizio Carbone, Andreas Helmut Christian Mann, Luca Piazza

The transition between different states in manganites can be driven by various external stimuli. Controlling these transitions with light opens the possibility to investigate the microscopic path through which they evolve. We performed femtosecond (fs) tra ...
