Symmetry and planar chirality of a protein measured on an angular basis in a transmission electron microscope
A. H. Tavabi, P. Rosi, R. B. G. Ravelli +16
In quantum mechanics, each conserved quantity (e.g., energy, position, linear momentum and angular momentum) is associated with a Hermitian operator. Its expected value can then be…
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…
Orbital angular momentum and energy loss characterization of plasmonic excitations in metallic nanostructures in TEM
Matteo Zanfrognini, Enzo Rotunno, Stefano Frabboni +4
Recently, a new device to measure the Orbital Angular Momentum (OAM) electronic spectrum after elastic/inelastic scattering in a transmission electron microscope has been introduce…
Electron beam shaping: how to control the e-beam propagation along atomic columns
E. Rotunno, A. Tavabi, E. Yucelen +5
In this work we report on a detailed analysis of the propagation of high energy electron beams having different shapes in a model system, namely [100] oriented zincblende GaN cryst…
