The electron microscope as a quantum gate
Peter Schattschneider, Stefan Löffler
We propose to use the topological charge instead of the spin variable to span a two-dimensional Hilbert space for beam electrons in a transmission electron microscope (TEM). In thi…
Using Cerenkov radiation for measuring the refractive index in thick samples by interferometric cathodoluminescence
Michael Stöger-Pollach, Stefan Löffler, Niklas Maurer +1
Cathodoluminescence (CL) has evolved into a standard analytical technique in (scanning) transmission electron microscopy. CL utilizes light excited due to the interactions between…
/2 Mode Converters and Vortex Generators for Electrons
Christian Kramberger, Stefan Löffler, Thomas Schachinger +3
In optics, mode conversion is an elegant way to switch between Hermite Gaussian and Laguerre Gaussian beam profiles and thereby impart orbital angular momentum onto the beam and to…
Entanglement and Entropy in Electron-Electron Scattering
Peter Schattschneider, Stefan Löffler, Herbert Gollisch +1
Treating Coulomb scattering of two free electrons in a stationary approach, we explore the momentum and spin entanglement created by the interaction. We show that a particular disc…
Peculiar Rotation of Electron Vortex Beams
Thomas Schachinger, Stefan Löffler, Michael Stöger-Pollach +1
Standard electron optics predicts Larmor image rotation in the magnetic lens field of a TEM. Introducing the possibility to produce electron vortex beams with quantized orbital ang…
