Transverse quantum-state characterization of programmable electron optics
Shengbo You, Paolo Rosi, Enzo Rotunno +6
Programmable electron optics -- electronically controlled phase plates -- underpin proposals from dose-efficient phase imaging to shaped-electron X-ray sources, nearly all assuming…
Quantum tomography of inelastic electron scattering \emph{via} orbital angular momentum states
Amir H. Tavabi, Alessio D'Errico, Paolo Rosi +10
The physical properties of a quantum system, whether pure or mixed, are described fully by its density matrix. Recovery of the density matrix through projective measurements -- ref…
Designing electrostatic MEMS-based electron optics: the case of the spiral phase plate
Payam Habibdazeh Kavkani, Amir H. Tavabi, Paolo Rosi +8
A new generation of microfabricated MEMS for electron optics is changing electron microscopy for the better. These devices allow operations on the electron beam that are impossible…
Realization of a Pre-Sample Photonic-based Free-Electron Modulator in Ultrafast Transmission Electron Microscopes
Beatrice Matilde Ferrari, Cameron James Richard Duncan, Michael Yannai +16
Spatial and temporal light modulation is a well-established technology that enables dynamic shaping of the phase and amplitude of optical fields, significantly enhancing the resolu…
Computational ghost imaging for transmission electron microscopy
Akhil Kallepalli, Lorenzo Viani, Daan Stellinga +9
While transmission electron microscopes (TEM) can achieve a much higher resolution than optical microscopes, they face challenges of damage to samples during the high energy proces…
Alignment of electron optical beam shaping elements using a convolutional neural network
E. Rotunno, A. H. Tavabi, P. Rosi +4
A convolutional neural network is used to align an orbital angular momentum sorter in a transmission electron microscope. The method is demonstrated using simulations and experimen…
Experimental demonstration of an electrostatic orbital angular momentum sorter for electrons
Amir H. Tavabi, Paolo Rosi, Giulio Pozzi +9
We report the first experimental demonstration of an electrostatic electron orbital angular momentum (OAM) sorter, which can be used to analyze the OAM states of electrons in a tra…
Realization of electron vortices with large orbital angular momentum using miniature holograms fabricated by electron beam lithography
E. Mafakheri, A. H. Tavabi, P. -H. Lu +9
Free electron beams that carry high values of orbital angular momentum (OAM) possess large magnetic moments along the propagation direction. This makes them an ideal probe for meas…
A Stern-Gerlach-like approach to electron orbital angular momentum measurement
Tyler R. Harvey, Benjamin J. McMorran
Many methods now exist to prepare free electrons into orbital angular momentum states, and the predicted applications of these electron states as probes of materials and scattering…
Spin polarisation with electron Bessel beams
Peter Schattschneider, Vincenzo Grillo
The theoretical possibility to use an electron microscope as a spin polarizer is studied. It turns out that a Bessel beam passing a standard magnetic objective lens is intrinsicall…
