Ultra-stable and versatile high-energy resolution setup for attosecond photoelectron spectroscopy
Sizuo Luo, Robin Weissenbilder, Hugo Laurell +12
Attosecond photoelectron spectroscopy is often performed with interferometric experimental setups that require outstanding stability. We demonstrate and characterize in detail an a…
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…
Probing electronic decoherence with high-resolution attosecond photoelectron interferometry
David Busto, Hugo Laurell, Daniel Finkelstein Shapiro +14
Quantum coherence plays a fundamental role in the study and control of ultrafast dynamics in matter. In the case of photoionization, entanglement of the photoelectron with the ion…

Jasper Peschel, David Busto, Marius Plach +11
Ionization of atoms and molecules by absorption of a light pulse results in electron wavepackets carrying information on the atomic or molecular structure as well as on the dynamic…
Fission of charged nano-hydrated ammonia clusters -- microscopic insights on the nucleation processes
Bart Oostenrijk, Darío Barreiro, Noelle Walsh +6
While largely studied on the macroscopic scale, the dynamics leading to nucleation and fission processes in atmospheric aerosols are still poorly understood at the molecular level.…

The photoionization of xenon atoms in the 70-100 eV range reveals several fascinating physical phenomena such as a giant resonance induced by the dynamic rearrangement of the elect…
Attosecond timing of electron emission from a molecular shape resonance
S. Nandi, E. Plésiat, S. Zhong +11
Shape resonances in physics and chemistry arise from the spatial confinement of a particle by a potential barrier. In molecular photoionization, these barriers prevent the electron…
Controlling the Photoelectric Effect in the Time Domain
Yu-Chen Cheng, Sara Mikaelsson, Saikat Nandi +9
When an atom or molecule absorbs a high-energy photon, an electron is emitted with a well-defined energy and a highly-symmetric angular distribution, ruled by energy quantization a…
Phase Control of Attosecond Pulses in a Train
Chen Guo, Anne Harth, Stefanos Carlström +12
Ultrafast processes in matter can be captured and even controlled by using sequences of few-cycle optical pulses, which need to be well characterized, both in amplitude and phase.…

One of the most ubiquitous techniques within attosecond science is the so-called Reconstruction of Attosecond Bursts by Interference of Two-Photon Transitions (RABBITT). Originally…
Fano's propensity rule in angle-resolved attosecond pump-probe photoionization
