Spin polarization and attosecond time delay in photoemission from solids

Mauro Fanciulli

In the photoemission process electrons are emitted from a solid upon excitation with UV light. From the measurement of their energy and momentum, angle-resolved photoemission spectroscopy (ARPES) allows to reconstruct the electronic properties of the solid ...

Symmetry breakdown of electron emission in extreme ultraviolet photoionization of argon

Eugenio Ferrari

Short wavelength free-electron lasers (FELs), providing pulses of ultrahigh photon intensity, have revolutionized spectroscopy on ionic targets. Their exceptional photon flux enables multiple photon absorptions within a single femtosecond pulse, which in t ...

Attosecond coherent control of free-electron wave functions using semi-infinite light fields

Fabrizio Carbone, Giovanni Maria Vanacore, Ivan Madan, Enrico Pomarico, Gabriele Berruto, Ido Kaminer, Brett Eugene Barwick

Light–electron interaction is the seminal ingredient in free-electron lasers and dynamical investigation of matter. Pushing the coherent control of electrons by light to the attosecond timescale and below would enable unprecedented applications in quantum ...

Second Harmonic Generation Dynamics in Plasmonic Nanoparticles

Olivier Martin, Jérémy Butet, Gabriel David Bernasconi

Due to its symmetry properties, second-harmonic generation in plasmonic nanostructures enables the observation of even-parity modes that couple weakly to the far field. Consequentially, those modes radiate less and thus have a longer lifetime. Using a full ...

A time-gated large-array SPAD camera for picosecond resolution real-time FLIM

Edoardo Charbon, Claudio Bruschini, Arin Can Ülkü

Single-photon avalanche diode (SPAD) arrays have recently emerged as promising detectors for many wide-field fluorescence lifetime imaging microscopy (FLIM) applications, thanks to their picosecond range temporal resolution, single-photon sensitivity and f ...

Design and implementation of an optimal laser pulse front tilting scheme for ultrafast electron diffraction in reflection geometry with high temporal resolution

Fabrizio Carbone, Giovanni Maria Vanacore, Giulia Fulvia Mancini, Malte Oppermann, Francesco Pennacchio, Rajeswari Jayaraman

Ultrafast electron diffraction is a powerful technique to investigate out-of-equilibrium atomic dynamics in solids with high temporal resolution. When diffraction is performed in reflection geometry, the main limitation is the mismatch in group velocity be ...

Charge migration and charge transfer in molecular systems

Majed Chergui, Ursula Röthlisberger, Jacques-Edouard Moser, Andrea Cannizzo, Natalie Renuka Banerji, Joël Teuscher, Christopher Alexander Arrell, Pablo Lopez Tarifa, Elisa Liberatore

The transfer of charge at the molecular level plays a fundamental role in many areas of chemistry, physics, biology and materials science. Today, more than 60 years after the seminal work of R. A. Marcus, charge transfer is still a very active field of res ...
