Adiabatic dynamics in a V-type quantum system by oppositely chirped counterrotating circularly polarized laser pulses
D. Köhnke, T. Bayer, M. Wollenhaupt
Shaped free electron vortices (SEVs) have recently been studied using atomic (1+2) resonance-enhanced multiphoton ionization (REMPI) by oppositely chirped counterrotating circularl…

Measurement of ionization delays in atomic REMPI using photoelectron vortices
D. Köhnke, T. Bayer, M. Wollenhaupt
We study time-delays in atomic multiphoton ionization (MPI) using the phase-sensitive detection of photoelectron vortices. Photoelectron vortices are created by MPI with counter-ro…

Shaped free electron vortices
D. Köhnke, T. Bayer, M. Wollenhaupt
Since their first theoretical proposal [Ngoko Djiokap et al., Phys. Rev. Lett. 115, 113004 (2015)] and experimental demonstration [Pengel et al., Phys. Rev. Lett. 118, 053003 (2017…
