Spin-current correlations in photoionization of chiral molecules
Philip Caesar M. Flores, Stefanos Carlström, Serguei Patchkovskii +3
Chirality-induced spin selectivity (CISS) refers to phenomena where molecular chirality governs spin polarization. While symmetry simply requires chiral molecules to support spin-v…
Enantiosensitive molecular compass
Philip Caesar M. Flores, Stefanos Carlström, Serguei Patchkovskii +4
Chirality describes the asymmetry between an object and its mirror image and underlies diverse functionalities across molecular, mesoscopic and bulk matter. A particularly intrigui…
Generation of entanglement using a short-wavelength seeded free-electron laser
Saikat Nandi, Axel Stenquist, Asimina Papoulia +25
Quantum entanglement between the degrees of freedom encountered in the classical world is challenging to observe due to the surrounding environment. To elucidate this issue, we inv…
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…
Thomas--Reiche--Kuhn Correction for Truncated Configuration Interaction Spaces: Case of Laser-Assisted Dynamical Interference
Mattias Bertolino, Stefanos Carlström, Jasper Peschel +3
The Thomas--Reiche--Kuhn sum rule is used to form an effective potential that is added to the time-dependent configuration interaction singles (TDCIS) equations of motion in veloci…
Rydberg Atomic Antenna in Strongly Driven Multi-Electron Atoms
Stefanos Carlström, Jan Marcus Dahlström, Misha Yu Ivanov +1
We study the role of intermediate excitations of Rydberg states as an example of Kuchiev's "atomic antenna" in above-threshold ionization of xenon, in particular their effect on th…
General Time-Dependent Configuration-Interaction Singles II: The Atomic Case
Stefanos Carlström, Mattias Bertolino, Jan Marcus Dahlström +1
We present a specialization of the grid-based implementation of the time-dependent configuration-interaction singles described in the preceding paper (arXiv:2204.09966) to the case…
General Time-Dependent Configuration-Interaction Singles I: The Molecular Case
Stefanos Carlström, Michael Spanner, Serguei Patchkovskii
We present a grid-based implementation of the time-dependent configuration-interaction singles method suitable for computing the strong-field ionization of small gas-phase molecule…
Studying ultrafast Rabi dynamics with a short-wavelength seeded free-electron laser
Saikat Nandi, Edvin Olofsson, Mattias Bertolino +26
Rabi oscillations are periodic modulations of populations in two-level systems interacting with a time-varying field. They are ubiquitous in physics with applications in different…
Spatially and spectrally resolved quantum path interference with chirped driving pulses
Stefanos Carlström, Jana Preclíková, Eleonora Lorek +7
We measure spectrally and spatially resolved high-order harmonics generated in argon using chirped multi-cycle laser pulses. Using a stable, high-repetition rate laser we observe d…
Sub-cycle ionization dynamics revealed by trajectory resolved, elliptically-driven high-order harmonic generation
E. W. Larsen, S. Carlstrom, E. Lorek +6
The sub-cycle dynamics of electrons driven by strong laser fields is central to the emerging field of attosecond science. We demonstrate how the dynamics can be probed through high…
High-order harmonic generation using a high-repetition-rate turnkey laser
Eleonora Lorek, Esben Witting Larsen, Christoph Michael Heyl +4
We generate high-order harmonics at high pulse repetition rates using a turnkey laser. High-order harmonics at 400 kHz are observed when argon is used as target gas. In neon we ach…
