Charge Migration in Heterocyclic Five-Membered Rings
Sucharita Giri, Gopal Dixit, Jean Christophe Tremblay
This contribution presents numerical simulations of N-electron dynamics in heterocyclic five-membered ring molecules to shed light on the effect of molecular symmetry on charge mig…
Angle-Resolved Attosecond Streaking of Twisted Attosecond Pulses
Irfana N. Ansari, Deependra S. Jadoun, Gopal Dixit
The present work focuses on the characterisation of the amount of orbital angular momentum (OAM) encoded in the twisted attosecond pulses via energy- and angle-resolved attosecond…
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…
Simultaneous control of harmonic yield and energy cutoff of high-harmonic generation using seeded plasmonic-enhanced fields
Irfana N. Ansari, M. S. Mrudul, Marcelo F. Ciappina +2
We study high-order harmonic generation (HHG) driven by seeded plasmonic-enhanced fields. On one hand, plasmonic-enhanced fields have shown a great potential to extend the HHG cuto…
