Ultrafast imaging of molecular chirality with photoelectron vortices
Published:
Motivated by advances in electron vortex states, which carry orbital angular momentum (OAM), we exploit conserved helicity inherent in photoelectrons carrying OAM from a chiral target to propose a new ultrafast chiral imaging technique, dubbed photoelectron vortex dichroism (PEVD). We theoretically demonstrate huge asymmetry in OAM-resolved photoelectron emission, sensitive to molecular chirality, for electrons ionized by strong linearly polarized fields.
Entanglement of Orbital Angular Momentum in Non-Sequential Double Ionization
Published:
I will discuss our new results on entanglement and orbital angular momentum (OAM) in non-sequential double ionization (NSDI). We demonstrate that there is entanglement in the OAM between the two photoelectrons in NSDI. Due to the quantization of OAM, this entanglement is easily quantified and has a simple physical interpretation in terms of conservation laws. Using the strong-field approximation, we quantify the entanglement for a large range of parameters, isolating the best targets for experimentalists. We also explore efficient methods to quantify and measure the entanglement, in particular by using an entanglement witness. Importantly, the methodology presented here could be applied to many other systems to help understand and exploit entanglement in attosecond processes.
