Description
The Auger process is well known as a spectroscopic fingerprint for elemental identification, but it also provides a unique platform for studying electron entanglement. To gain theoretical insight into this latter aspect, we address entanglement formation in a model molecule following electronic transitions induced by a light-pulse, and its subsequent disappearance due to decoherence effects arising from the molecule nuclear dynamics and electronic de-excitation. In this pilot study, we consider a simplified molecular system coupled to a discretised continuum, allowing for a qualitative yet approximation-free exploration of entanglement dynamics. Our model is based on parameters similar to those of the Beryllium dimer, whose low dissociation energy allows us to examine possible connections between entanglement and molecular dissociation.We will also briefly report on work in progress, where we are exploring how additional fields or pulses can manipulate entanglement between the photoelectron and the Auger electron.
