Electromagnetic Coherent Electron Control

Abstract

Electron quantum optics offers fascinating insights into the dynamic electron evolution processes governed by quantum effects, attractive for novel electronic processing or sensing devices. A key requirement for these developments is to coherently and electromagnetically confine and control the electron evolution process and the ability to correctly describe the manifesting quantum effects related to the wave nature of the electron, e.g., interference. This work provides an overview of research conducted on using specifically shaped electric and magnetic fields to influence the electron evolution in nanostructures. The Wigner based quantum transport modeling approach is used to simulate the transport and to highlight quantum effects.
