Magnetic-field effect in high-order above-threshold ionization
Kang Lin, Simon Brennecke, Hongcheng Ni +15
We experimentally and theoretically investigate the influence of the magnetic component of an electromagnetic field on high-order above-threshold ionization of xenon atoms driven b…
Photoelectron energy peaks shift against the radiation pressure in strong field ionization
Kang Lin, Sebastian Eckart, Alexander Hartung +8
The photoelectric effect describes the ejection of an electron upon absorption of one or several photons. The kinetic energy of this electron is determined by the photon energy red…
Measuring the photoelectron emission delay in the molecular frame
Jonas Rist, Kim Klyssek, Nikolay M. Novikovskiy +22
If matter absorbs a photon of sufficient energy it emits an electron. The question of the duration of the emission process has intrigued scientists for decades. With the advent of…
Fourfold Differential Photoelectron Circular Dichroism
K. Fehre, N. M. Novikovskiy, S. Grundmann +28
We report on a joint experimental and theoretical study of photoelectron circular dichroism (PECD) in methyloxirane. By detecting O 1s-photoelectrons in coincidence with fragment i…
A new route for enantio-sensitive structure determination by photoelectron scattering on molecules in the gas phase
K. Fehre, N. M. Novikovskiy, S. Grundmann +28
X-ray as well as electron diffraction are powerful tools for structure determination of molecules. Studies on randomly oriented molecules in the gas-phase address cases in which mo…
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…
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…
The role of spin and angular momentum in strong-field ionization
D. Trabert, A. Hartung, S. Eckart +7
The spin polarization of electrons from multiphoton ionization of Xe by 395 nm circularly polarized laser pulses at W/cm has been measured. At this photon energ…
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…
Soliton explosion driven multi-octave supercontinuum generation by geometry-enforced dispersion design in antiresonant hollow-core fibers
Rudrakant Sollapur, Daniil Kartashov, Michael Zürch +9
Ultrafast supercontinuum generation in gas-filled waveguides is one enabling technology for many intriguing application ranging from attosecond metrology towards biophotonics, with…
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…
Imaging the He quantum halo state using a free electron laser
S. Zeller, M. Kunitski, J. Voigtsberger +24
We report on coulomb explosion imaging of the wavefunction of the quantum halo system He. Each atom of this system is ionized by tunnelionization in a femto second laser pulse…
