Magnetic fields alter tunneling in strong-field ionization
A. Hartung, S. Eckart, S. Brennecke +16
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 pa…
Multiphoton Double Ionization of Helium at 394nm - a Fully Differential Experiment
K. Henrichs, S. Eckart, A. Hartung +11
We report on a kinematically complete experiment on strong field double ionization of helium using laser pulses with a wavelength of 394\,nm and intensities of $3.5-5.7\times10^{14…
Direct observation of interatomic Coulombic decay and subsequent ion-atom scattering in helium nanodroplets
F. Wiegandt, F. Trinter, K. Henrichs +13
We report on the experimental observation of interatomic Coulombic decay (ICD) in pure He nanoclusters of mean sizes between 5000 and 30000 and the subsequent scatt…
Timing Recollision in Nonsequential Double Ionization by Intense Elliptically Polarized Laser Pulses
H. Kang, K. Henrichs, M. Kunitski +10
We examine correlated electron and doubly charged ion momentum spectra from strong field double ionization of Neon employing intense elliptically polarized laser pulses. An ellipti…
Double-slit photoelectron interference in strong-field ionization of the neon dimer
Maksim Kunitski, Nicolas Eicke, Pia Huber +13
Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental c…
Ultrafast Preparation and Detection of Ring Currents in Single Atoms
Sebastian Eckart, Maksim Kunitski, Martin Richter +16
Quantum particles can penetrate potential barriers by tunneling (1). If that barrier is rotating, the tunneling process is modified (2,3). This is typical for electrons in atoms, m…
Experimental Evidence for Selection Rules in Multiphoton Double Ionization of Helium
K. Henrichs, S. Eckart, A. Hartung +10
We report on the observation of phase space modulations in the correlated electron emission after strong field double ionization of helium using laser pulses with a wavelength of 3…
Sub-Cycle Interference upon Tunnel-Ionization by Counterrotating Two-Color Fields
S. Eckart, M. Kunitski, I. Ivanov +12
We report on three-dimensional (3D) electron momentum distributions from single ionization of helium by a laser pulse consisting of two counterrotating circularly polarized fields…
Electron spin polarization in strong-field ionization of Xenon atoms
Alexander Hartung, Felipe Morales, Maksim Kunitski +10
As a fundamental property of the electron, the spin plays a decisive role in the electronic structure of matter from solids to molecules and atoms, e.g. causing magnetism. Yet, des…
Observation of enhanced chiral asymmetries in the inner-shell photoionization of uniaxially oriented methyloxirane enantiomers
Maurice Tia, Martin Pitzer, Gregor Kastirke +38
Most large molecules are chiral in their structure: they exist as two enantiomers, which are mirror images of each other. Whereas the rovibronic sublevels of two enantiomers are al…
Non-Sequential Double Ionization by Counter Rotating Circularly Polarized Two-Color Laser Fields
S. Eckart, M. Richter, M. Kunitski +11
We report on non-sequential double ionization of Ar by a laser pulse consisting of two counter rotating circularly polarized fields (390 nm and 780 nm). The double ionization proba…
Observation of Electron Energy Discretization in Strong Field Double Ionization
Kevin Henrichs, Markus Waitz, Florian Trinter +11
We report on the observation of discrete structures in the electron energy distribution for strong field double ionization of Argon at 394 nm. The experimental conditions were chos…
