Ultrafast generation and control of an electron vortex beam via chiral plasmonic near fields

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

Vortex-carrying matter waves, such as chiral electron beams, are of significant interest in both applied and fundamental science. Continuous-wave electron vortex beams are commonly prepared via passive phase masks imprinting a transverse phase modulation o ...

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

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

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 ...

Electron diffraction by plasmon waves

Fabrizio Carbone, Brett Eugene Barwick

An electron beam traversing a structured plasmonic field is shown to undergo diffraction with characteristic angular patterns of both elastic and inelastic outgoing electron components. In particular, a plasmonic grating (e.g., a standing wave formed by tw ...

Imaging and controlling plasmonic interference fields at buried interfaces

Fabrizio Carbone, Brett Eugene Barwick, Tom Theodorus Antonius Lummen, Gabriele Berruto

Capturing and controlling plasmons at buried interfaces with nanometre and femtosecond resolution has yet to be achieved and is critical for next generation plasmonic devices. Here we use light to excite plasmonic interference patterns at a buried metal-di ...

Simultaneous observation of the quantization and the interference pattern of a plasmonic near-field

Fabrizio Carbone, Luca Piazza, Brett Eugene Barwick, Yoshie Murooka, Tom Theodorus Antonius Lummen

Surface plasmon polaritons can confine electromagnetic fields in subwavelength spaces and are of interest for photonics, optical data storage devices and biosensing applications. In analogy to photons, they exhibit wave-particle duality, whose different as ...

Design and implementation of a fs-resolved transmission electron microscope based on thermionic gun technology

Fabrizio Carbone, Luca Piazza, Brett Eugene Barwick

In this paper, the design and implementation of a femtosecond-resolved ultrafast transmission electron microscope is presented, based on a thermionic gun geometry. Utilizing an additional magnetic lens between the electron acceleration and the nominal cond ...
