Electron Coherence

Electron coherence is a fundamental quantum phenomenon in today’s ultrafast physics and chemistry research. Based on attosecond pump–probe schemes, ultrafast X-ray photoelectron imaging of molecules was used to monitor the coherent electron dynamics which is created by an XUV pulse. We performed simulations on the molecular ion H 2 + by numerically solving time-dependent Schrödinger equations. It was found that the X-ray photoelectron angular and momentum distributions depend on the time delay between the XUV pump and soft X-ray probe pulses. Varying the polarization and helicity of the soft X-ray probe pulse gave rise to a modulation of the time-resolved photoelectron distributions. The present results provide a new approach for exploring ultrafast coherent electron dynamics and charge migration in reactions of molecules on the attosecond time scale.

Electron Coherence

In narrow channels the properties of the sidewalls can have a crucial effect on both the physics and any device functionality of the electronic transport through these structures. We assess the use of electron beam and "dry etching" fabrication techniques to define sidewalls by studying the influence of the sidewalls on the quantum transmission through the channels and, in particular, show the sidewall scattering to be inelastic in nature and to have implications ranging from electron heating to electron coherence effects.
