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...

High-Resolution Momentum Imaging—From Stern’s Molecular Beam Method to the COLTRIMS Reaction Microscope
Multi-particle momentum imaging experiments are now capable of providing detailed information on the properties and the dynamics of quantum systems in Atomic, Molecular and Photon (AMO) physics. Historically, ...

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...

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...

Quantum thermodynamic processes: a control theory for machine cycles
The minimal set of thermodynamic control parameters consists of a statistical (thermal) and a mechanical one. These suffice to introduce all the pertinent thermodynamic variables; thermodynamic processes can t...

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 ...
