Title: Spin polarization and migration
In my talk, I will discuss our recent research on dynamical electron spin in atoms and small molecules; in the first part, I will discuss various ways of efficiently generating spin-polarized photoelectrons from rare gas atom, both in the strong-field regime, we can use the photoelectron spin- and angle-resolved spectrum to image the ion core hole motion, and in the weak-field regime, employing the Fano resonances to produce photoelectrons with a high degree of spin polarization.
In the second part I will introduce the new exciting field of spin migration; by ionizing an argon dimer, we set a nuclear wavepacket in motion. This wavepacket in turn drives the electronic motion, and due to the spin–orbit interaction (which is on the same order of magnitude as the splitting of the vibrational states), we drive non-trivial spin density fluctuations, extending over the molecular structure. We call this phenomenon spin migration.
