Energy domain versus time domain precursor fluctuations above the Verwey transition in magnetite

Henrik Moodysson Rønnow, Fabrizio Carbone, Gregory Scott Tucker, Simone Borroni

We study the dynamics and interactions of the critical fluctuations of the Verwey transition in magnetite (Fe3O4) in the pretransition region by means of inelastic neutron scattering experiments on a natural single crystal. We find that a Delta(5) mode int ...

Laser-Induced Skyrmion Writing and Erasing in an Ultrafast Cryo-Lorentz Transmission Electron Microscope

Henrik Moodysson Rønnow, Fabrizio Carbone, Ivan Madan, Giovanni Maria Vanacore, Enrico Pomarico, Gabriele Berruto, Ping Huang, Yoshie Murooka

We demonstrate that light-induced heat pulses of different duration and energy can write Skyrmions in a broad range of temperatures and magnetic field in FeGe. Using a combination of camera-rate and pump- probe cryo-Lorentz transmission electron microscopy ...

Generation and control of localized terahertz fields in photoemitted electron plasmas

Fabrizio Carbone, Ivan Madan, Giovanni Maria Vanacore, Simone Gargiulo, Francesco Barantani

Dense micron-sized electron plasmas, such as those generated upon irradiation of nanostructured metallic surfaces by intense femtosecond laser pulses, constitute a rich playground to study light-matter interactions, many-body phenomena, and out-of-equilibr ...

Probing the electron-phonon interaction in correlated systems with coherent lattice fluctuation spectroscopy

Fabrizio Carbone, Frank van Mourik, Christopher Alexander Arrell, Edoardo Baldini, Andreas Helmut Christian Mann

Tailoring the properties of correlated oxides is accomplished by chemical doping, pressure, temperature, or magnetic field. Photoexcitation is a valid alternative to reach out-of-equilibrium states otherwise inaccessible. Here, we quantitatively estimate t ...

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. ...

Method for manufacturing an active structure for a radiation detector and polymeric mold for the method

Arnaud Bertsch, Fabrizio Carbone, Alessandro Mapelli, Veronica Leccese, Michele Caldara

A method for manufacturing a scintillation detector structure including the steps of forming a plurality of first structures into a surface of a substrate to form a patterned substrate, filling the plurality of first structures and covering the surface of ...

Clocking the onset of bilayer coherence in a high-Tc cuprate

Fabrizio Carbone, Frank van Mourik, Edoardo Baldini, Christopher Alexander Arrell, Andreas Helmut Christian Mann

In cuprates, a precursor state of superconductivity is speculated to exist above the critical temperature T-c. Here we show via a combination of far-infrared ellipsometry and ultrafast broadband optical spectroscopy that signatures of such a state can be o ...

Real-Time Observation of Phonon-Mediated σ−π Interband Scattering in MgB2

Fabrizio Carbone, Edoardo Baldini, Andreas Helmut Christian Mann, Simone Borroni

In systems having an anisotropic electronic structure, such as the layered materials graphite, graphene, and cuprates, impulsive light excitation can coherently stimulate specific bosonic modes, with exotic consequences for the emergent electronic properti ...

Unifying Optical Frequency Metrology with Free-Electron Spectroscopy

Tobias Kippenberg, Rui Ning Wang, Fabrizio Carbone, Arslan Sajid Raja, Thomas La Grange, Yujia Yang, Alexey Sapozhnik, Bruce Michael Raleigh Weaver, Paolo Cattaneo

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. ...

Revisiting the Excitation of the Low-Lying ^{181m}Ta Isomer in Optical Laser-Generated Plasma

Fabrizio Carbone, Ivan Madan, Giovanni Maria Vanacore, Simone Gargiulo, Veronica Leccese, Benoît Guilhem Michel Binh Truc, Kjeld Adrianus Antonius Gerardus Beeks, Paolo Usai

The excitation of the ^{181m}Ta isomer in the laser-plasma scenario was claimed to have been observed more than two decades ago. However, the reported experimental findings-and the respective high excitation rate-were later questioned as they could not be ...

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

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

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 ...
