Workload Identification with Physical Side Channels for AI Governance
Simone Gargiulo, Gabriel Kulp
AI compute verification is one of the first tangible and tractable points for international policy aimed at AI governance. Determining whether frontier labs, or any operator, compl…
Revisiting the excitation of the low-lying Ta isomer in optical laser-generated plasma
Simone Gargiulo, Ivan Madan, Benoit Truc +5
The excitation of the Ta isomer in the laser-plasma scenario was claimed to have been observed more than two decades ago. However, the reported experimental finding…
Microstructured Plastic Scintillators For Beam Profiling In Medical Accelerators
Veronica Leccese, Michele Caldara, Samuele Bisi +6
A novel beam profiler based on microstructured scintillation resin is presented. The detector consists of a bundle of waveguides, with an active area of 30 x 30 mm and a pitch…
Observation of a new light-induced skyrmion phase in the Mott insulator Cu2OSeO3
Alexey A. Sapozhnik, Benoit Truc, Phoebe Tengdin +10
We report the discovery of a novel skyrmion phase in the multiferroic insulator Cu2OSeO3 for magnetic fields below the equilibrium skyrmion pocket. This phase can be accessed by ex…
Ultrafast Transverse Modulation of Free Electrons by Interaction with Shaped Optical Fields
I. Madan, V. Leccese, A. Mazur +11
Spatio-temporal shaping of electron beams is a bold frontier in electron microscopy, enabling new routes toward spatial-resolution enhancement, selective probing, low-dose imaging…
Charge dynamics electron microscopy: nanoscale imaging of femtosecond plasma dynamics
Ivan Madan, Eduardo J. C. Dias, Simone Gargiulo +11
Understanding and actively controlling the spatio-temporal dynamics of non-equilibrium electron clouds is fundamental for the design of light and electron sources, novel high-power…
Coherent Smith-Purcell -Ray Emission
Kamran Akbari, Simone Gargiulo, Fabrizio Carbone +1
We investigate the Smith-Purcell emission produced by electron- or ion-beam-driven coherent excitation of nuclei arranged in periodic crystal lattices. The excitation and subsequen…
