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…
Photoelectron signature of dressed-atom stabilization in intense XUV field
Edvin Olofsson, Jan Marcus Dahlström
Non-perturbative resonant multiphoton ionization is studied using the resolvent operator technique. Scaling parameters for effective two-level Hamiltonians are computed for…
Gauge-invariant absorption of light from a coherent superposition of states
Axel Stenquist, Felipe Zapata, Jan Marcus Dahlström
Absorption and emission of light is studied theoretically for excited atoms in coherent superposition of states subjected to isolated attosecond pulses in the extreme ultraviolet r…
