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…
Spatial aberrations in high-order harmonic generation
Marius Plach, Federico Vismarra, Elisa Appi +11
We investigate the spatial characteristics of high-order harmonic radiation generated in argon, and observe cross-like patterns in the far field. An analytical model describing har…
Chromatic aberrations correction of attosecond high-order harmonic beams by flat-top spatial shaping of the fundamental beam
K. Veyrinas, M. Plach, J. Peschel +16
Attosecond pulses created by high-order harmonic generation in gases often exhibit strong chromatic aberrations, arising from the broad bandwidth and wavelength-dependent nonlinear…
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…
Resonant two-photon ionization of helium atoms studied by attosecond interferometry
Lana Neoričić, David Busto, Hugo Laurell +15
We study resonant two-photon ionization of helium atoms via the , and P states using the 15 harmonic of a titanium-sapphire laser for the exc…
The Kinetic Energy of PAH Dication and Trication Dissociation Determined by Recoil-Frame Covariance Map Imaging
Jason W. L. Lee, Denis S. Tikhonov, Felix Allum +28
We investigated the dissociation of dications and trications of three polycyclic aromatic hydrocarbons (PAHs), fluorene, phenanthrene, and pyrene. PAHs are a family of molecules ub…
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…
Complete characterization of multi-channel single photon ionization
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…
Dissociation dynamics of the diamondoid adamantane upon photoionization by XUV femtosecond pulses
Sylvain Maclot, Jan Lahl, Jasper Peschel +10
This work presents a photodissociation study of the diamondoid adamantane using extreme ultraviolet femtosecond pulses. The fragmentation dynamics of the dication is unraveled by t…
A Versatile Velocity Map Ion-Electron Covariance Imaging Spectrometer for High-Intensity XUV Experiments
Linnea Rading, Jan Lahl, Sylvain Maclot +8
We report on the design and performance of a velocity map imaging (VMI) spectrometer optimized for experiments using high-intensity extreme ultraviolet (XUV) sources such as laser-…
Spatio-temporal coupling of attosecond pulses
Hampus Wikmark, Chen Guo, Jan Vogelsang +12
The shortest light pulses produced to date are of the order of a few tens of attoseconds, with central frequencies in the extreme ultraviolet range and bandwidths exceeding tens of…
Micro-focusing of broadband high-order harmonic radiation by a double toroidal mirror
Hélène Coudert-Alteirac, Hugo Dacasa, Filippo Campi +16
We present an optical system based on two toroidal mirrors in a Wolter configuration to focus broadband XUV radiation. Optimization of the focusing optics alignment is carried out…
