Controlling polarization of attosecond pulses with plasmonic-enhanced bichromatic counter-rotating circularly polarised fields
Irfana N. Ansari, Cornelia Hofmann, Lukas Medišauskas +3
The use of bichromatic counter-rotating laser field is known to generate high-order harmonics with non-zero ellipticity. By combining such laser field with a plasmonic-enhanced spa…
Probing Electronic Fluxes via Time-Resolved X-ray Scattering
Gunter Hermann, Vincent Pohl, Gopal Dixit +1
The current flux density is a vector field that can be used to describe theoretically how electrons flow in a system out-of-equilibrium. In this work, we unequivocally demonstrate…
Signatures of the orbital angular momentum of an infrared light beam in the two-photon transition matrix element: A step toward attosecond chronoscopy of photoionization
Sucharita Giri, Misha Ivanov, Gopal Dixit
We present a theory of time-resolved photoionisation in the presence of a vortex beam. In a pump-probe setup, an extreme ultraviolet or an x-ray pump pulse triggers ionization, whi…
