Entanglement Transfer in a Composite Electron-Ion-Photon System
Axel Stenquist, Jakob Nicolai Bruhnke, Felipe Zapata +1
We study how entanglement in photoionization is transferred from an electron-ion pair to an electron-photon pair by fluorescence. Time-resolved von Neumann entropies are used to es…

Mollow-like triplets in ultra-fast resonant absorption
Axel Stenquist, Felipe Zapata, Edvin Olofsson +5
We show that resonant absorption of smooth laser fields can yield Mollow-like triplet patterns. General conditions for such triplets are derived and illustrated with a super-Gaussi…

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…
