The collision between two electrons is treated in a time-dependent three-dimensional approach involving a two-electron wave packet, which is composed of stationary solutions of the two-electron Schroedinger equation with Coulomb interaction. As a qua

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 discretisation provides an estimate of the von Neumann entropy of the one-

Progress in Surface Science
The emission of electron pairs from surfaces has the power to reveal details about the electron–electron interaction in condensed matter. This process, stimulated by a primary electron or photon beam, has been studied both in experiment and theory

The spin texture of a Dirac-type surface state in W(110) lends itself to study spin-dependent effects in electron spectroscopies that show up very clearly. Firstly, we report on spin-resolved photoemission calculations and separate the spin polarizat

We explore by theory and experiment the effects of spin–orbit coupling (SOC) on the pair creation of electrons by spin-polarized primary electrons incident on a pseudomorphic monolayer of Au on Ir(111). An ab-initio calculation of the electronic st

We describe the principle, the preparation, and the calibration of a spin-polarizing electron mirror in multichannel spin polarimetry. We show data obtained by two independent devices (a goniometer-type LEED set-up and a momentum-microscope set-up) a

Here, the authors make connection to the foundation of quantum mechanics. As stated by Schr\"odinger, entanglement is ``the characteristic trait of quantum mechanics'' and seemingly at odds with the description of nature. In this joint experimental a

As Stern–Gerlach type spin filters do not work with electrons, spin analysis of electron beams is accomplished by spin-dependent scattering processes based on spin–orbit or exchange interaction. Existing polarimeters are single-channel devices ch

The energy and azimuthal angle dependencies of the asymmetry of spin-polarized low-energy electrons ((00) beam) elastically scattered from a W(110) surface, have been studied before and after irradiated with slow Ar+ ions with energies of 200 eV, 500

For spin-polarized low-energy electrons impinging on a crystalline surface, an important reaction channel is the collision with a bound valence electron of opposite spin, followed by the emission of a correlated electron pair with antiparallel spins.
