Spin-Polarized Photoelectrons in the Vicinity of Spectral Features
Stefanos Carlström, Rezvan Tahouri, Asimina Papoulia +4
It has been shown by Fano (1969) https://doi.org/10.1103/PhysRev.178.131 that photoionization of a cæsium atom by a laser pulse tuned to the vicinity of a Cooper minimum generates…
Control of Spin Polarization through Recollisions
Stefanos Carlström, Jan Marcus Dahlström, Misha Yu Ivanov +2
Using only linearly polarized light, we study the possibility of generating spin-polarized photoelectrons from xenon atoms. No net spin polarization is possible, since the xenon gr…
Role of Spin-Orbit Coupling in High-order Harmonic Generation Revealed by Super-Cycle Rydberg Trajectories
Nicola Mayer, Samuel Beaulieu, Alvaro Jimenez-Galan +7
High-harmonic generation is typically thought of as a sub-laser-cycle process, with the electron's excursion in the continuum lasting a fraction of the optical cycle. However, it w…
Imprinting chirality on atoms using synthetic chiral light fields
Nicola Mayer, Serguei Patchkovskii, Felipe Morales +2
Atoms are usually thought of as achiral objects. However, one can construct superpositions of atomic states that are chiral [1]. Here we show how to excite such superpositions with…
Propensity rules for photoelectron circular dichroism in strong field ionization of chiral molecules
Andres F. Ordonez, Olga Smirnova
Chiral molecules ionized by circularly polarized fields produce a photoelectron current orthogonal to the polarization plane. This current has opposite directions for opposite enan…
Control of attosecond light polarization in two-color bi-circular fields
Álvaro Jiménez-Galán, Nick Zhavoronkov, David Ayuso +6
We develop theoretically and confirm both numerically and experimentally a comprehensive analytical model which describes the propensity rules in the emission of circularly polariz…
Electron correlations and pre-collision in the re-collision picture of high harmonic generation
Zdeněk Mašín, Alex G. Harvey, Michael Spanner +3
We discuss the seminal three-step model and the recollision picture in the context of high harmonic generation in molecules. In particular, we stress the importance of multi-electr…
Ultrafast Preparation and Detection of Ring Currents in Single Atoms
Sebastian Eckart, Maksim Kunitski, Martin Richter +16
Quantum particles can penetrate potential barriers by tunneling (1). If that barrier is rotating, the tunneling process is modified (2,3). This is typical for electrons in atoms, m…
Electron spin polarization in strong-field ionization of Xenon atoms
Alexander Hartung, Felipe Morales, Maksim Kunitski +10
As a fundamental property of the electron, the spin plays a decisive role in the electronic structure of matter from solids to molecules and atoms, e.g. causing magnetism. Yet, des…
Attosecond control of spin polarization in electron-ion recollision driven by intense tailored fields
David Ayuso, Álvaro Jiménez-Galán, Felipe Morales +2
We show that electrons recolliding with the ionic core upon tunnel ionization of noble gas atoms driven by a strong circularly polarized laser field in combination with a counter-r…
Opportunities for detecting ring currents using the attoclock set-up
Jivesh Kaushal, Felipe Morales, Olga Smirnova
Strong field ionization by circularly polarized laser fields from initial states with internal orbital momentum has interesting propensity rule: electrons counter-rotating with res…

Ingo Barth, Olga Smirnova
We apply the time-dependent analytical R-matrix theory to develop a movie of hole motion in a Kr atom upon ionization by strong circularly polarized field. We find rich hole dynami…
Interpreting Attoclock Measurements of Tunnelling Times
Lisa Torlina, Felipe Morales, Jivesh Kaushal +8
Resolving in time the dynamics of light absorption by atoms and molecules, and the electronic rearrangement this induces, is among the most challenging goals of attosecond spectros…
Time-resolving electron-core dynamics during strong field ionization in circularly polarized fields
Lisa Torlina, Jivesh Kaushal, Olga Smirnova
Electron-core interactions play a key role in strong-field ionization and the formation of photoelectron spectra. We analyse the temporal dynamics of strong field ionization associ…
Multidimensional high harmonic spectroscopy: A semi-classical perspective on measuring multielectron rearrangement upon ionization
Valeria Serbinenko, Olga Smirnova
High harmonic spectroscopy has the potential to combine attosecond temporal with sub-Angstrom spatial resolution of the early nuclear and multielectron dynamics in molecules. It in…
