Roadmap on structured waves
K. Y. Bliokh, E. Karimi, M. J. Padgett +47
Structured waves are ubiquitous for all areas of wave physics, both classical and quantum, where the wavefields are inhomogeneous and cannot be approximated by a single plane wave.…
A quantum logic gate for free electrons
Stefan Löffler, Thomas Schachinger, Peter Hartel +6
The topological charge of vortex electrons spans an infinite-dimensional Hilbert space. Selecting a two-dimensional subspace spanned by , a beam electron in a transmis…
Experimental Realisation of a π/2 Vortex Mode Converter for Electrons Using a Spherical Aberration Corrector
T. Schachinger, P. Hartel, P. -H. Lu +6
In light optics, beams with orbital angular momentum (OAM) can be produced by employing a properly-tuned two-cylinder-lens arrangement, also called /2 mode converter. It is not…
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…
/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…
