Open AccessAngular dependence of the Wigner time delay upon tunnel ionization of H2
When a very strong light field is applied to a molecule an electron can be ejected by tunneling. In order to quantify the time-resolved dynamics of this ionization process, the concept of the Wigner time delay...

Ultra-fast Dynamics in Quantum Systems Revealed by Particle Motion as Clock
To explore ultra-fast dynamics in quantum systems one needs detection schemes which allow time measurements in the attosecond regime. During the recent decades, the pump & probe two-pulse laser technique has p...

The Precision Limits in a Single-Event Quantum Measurement of Electron Momentum and Position
A modern state-of-the-art “quantum measurement” [The term “quantum measurement” as used here implies that parameters of atomic particles are measured that emerge from a single scattering process of quantum partic...

Magnetic fields alter strong-field ionization
When a strong laser pulse induces the ionization of an atom, momentum conservation dictates that the absorbed photons transfer their momentum to the electron and its parent ion. The sharing of the photon momen...

Synthesis of nanoporous organic/inorganic hybrid materials with adjustable pore size
Polystyrene (PS) nanofoams, prepared following the nanofoams continuity inversion of dispersions (NF-CID) principle, were utilized for the synthesis of nanoporous organic/inorganic hybrid materials. The pore size...

Open AccessImaging the square of the correlated two-electron wave function of a hydrogen molecule
The toolbox for imaging molecules is well-equipped today. Some techniques visualize the geometrical structure, others the electron density or electron orbitals. Molecules are many-body systems for which the co...

Imaging the structure of the trimer systems 4He3 and 3He4He2
Helium shows fascinating quantum phenomena unseen in any other element. In its liquid phase, it is the only known superfluid. The smallest aggregates of helium, the dimer (He2) and the trimer (He3) are, in their ...

Resonant Auger decay driving intermolecular Coulombic decay in molecular dimers
Intermolecular Coulombic decay transfers excess energy to neighbouring molecules, which then lose a low-energy (and, hence, genotoxic) electron; here the process is experimentally confirmed to be site-selectiv...

Understanding the role of phase in chemical bond breaking with coincidence angular streaking
Electron motion in chemical bonds occurs on an attosecond timescale. This ultrafast motion can be driven by strong laser fields. Ultrashort asymmetric laser pulses are known to direct electrons to a certain di...

Probing the tunnelling site of electrons in strong field enhanced ionization of molecules
Molecules show a much increased multiple ionization rate in a strong laser field as compared with atoms of similar ionization energy. A widely accepted model attributes this to the action of the joint fields o...

Ultrafast energy transfer between water molecules
Analysis of the electrons ionized from water dimers suggests that the energy absorbed by one molecule is rapidly transmitted to the second molecule from which the electron is ejected. This process, referred to...

Single photon double ionization of \(\mbox{\sffamily\bfseries H}_{\hbox{\sffamily\bfseries\fontsize{10}{12}\selectfont 2}}\) by circularly polarized photons at a photon energy of 160 eV
We report on fully differential cross sections for double ionization of H2 by a single circularly polarized photon of 160 eV energy. For an unequal sharing of the energy between the two electrons and a particular...

Finite-time quantum thermodynamic processes
We study a single quantum object subject to a parametrized distortion of its discrete spectrum and to a parametrized change of its state, which remains diagonal in its invariant energy eigenbasis. The Carnot ...
