Ultrafast momentum-resolved visualization of the interplay between phonon-mediated scattering and plasmons in graphite

Fabrizio Carbone, Ivan Madan, Alexey Sapozhnik, Thomas La Grange, Michele Puppin, Francesco Barantani

Scattering between charges and collective modes in materials governs phenomena such as electrical resistance, energy dissipation, and phase switching. Studying such scattering requires simultaneous access to ultrafast and momentum-resolved dynamics of sing ...

Ultrafast generation of hidden phases via energy-tuned electronic photoexcitation in magnetite

Fabrizio Carbone, Ivan Madan, Thomas La Grange, Benoît Guilhem Michel Binh Truc, Giovanni Maria Vanacore, Gabriele Berruto, Francesco Pennacchio, Paolo Usai

Phase transitions occurring in nonequilibrium conditions can evolve through high-energy intermediate states inaccessible via equilibrium adiabatic conditions. Because of the subtle nature of such hidden phases, their direct observation is extremely challen ...

Coherently amplified ultrafast imaging using a free-electron interferometer

Fabrizio Carbone

Accessing the low-energy non-equilibrium dynamics of materials and their polaritons with simultaneous high spatial and temporal resolution has been a bold frontier of electron microscopy in recent years. One of the main challenges lies in the ability to re ...

Coherent Amplification in Ultrafast Electron Microscopy

Fabrizio Carbone

We present free-electron imaging of sub-cycle spatio-temporal dynamics of 2D polariton wavepackets, demonstrating the first simultaneous time-, space-, and phase-resolved measurement of such phenomena, and resolving their novel features like vortex-anti-vo ...

Non-equilibrium Inter-site Dynamics of Photoexcited Kitaev α-Li2IrO3

Majed Chergui, Fabrizio Carbone, Hui-Yuan Chen, Rolf Baldwin Versteeg

The inter-site transition dynamics in a 2D honeycomb lattice of the Mott-insulator Li2irO3 was investigated via broadband time-resolved spectroscopy. Through two excitation regime corresponding to charger transfer (3.1eV) and across Mott-gap excitation (0. ...

Microstructured plastic scintillators for pencil beam profiling in proton-therapy accelerators

Alessandro Mapelli, Arnaud Bertsch, Fabrizio Carbone, Simone Gargiulo, Veronica Leccese

A novel beam profiler based on microstructured scintillation resin is presented. The detector consists of a bundle of waveguides, featuring an active area of 30 x 30 mm2 with a fill factor of 50% and a pitch of 400 mu m. This configuration is obtained by c ...

High-resolution MHz time- and angle-resolved photoemission spectroscopy based on a tunable vacuum ultraviolet source

Henrik Moodysson Rønnow, Marco Grioni, Fabrizio Carbone, Jan Hugo Dil, Thomas La Grange, Michele Puppin, Fei Guo

The time- and angle-resolved photoemission spectroscopy (trARPES) allows for direct mapping of the electronic band structure and its dynamic response on femtosecond timescales. Here, we present a new ARPES system, powered by a new fiber-based femtosecond l ...

Unifying Optical Frequency Metrology with Free-Electron Spectroscopy

Tobias Kippenberg, Fabrizio Carbone, Rui Ning Wang, Alexey Sapozhnik, Yujia Yang, Thomas La Grange, Arslan Sajid Raja

We establish a frequency link across the microwave, optical, and free-electron domains by a photonic chip-based electron phase modulator driven by a continuous-wave laser locked to a fully stabilized optical frequency comb. ...
