Electron correlation and interference effects in strong-field processes
Markus C. Kohler, Carsten Müller, Christian Buth +5
Several correlation and interference effects in strong-field physics are investigated. We show that the interference of continuum wave packets can be the dominant mechanism of high…
Extremely high-intensity laser interactions with fundamental quantum systems
A. Di Piazza, C. Müller, K. Z. Hatsagortsyan +1
The field of laser-matter interaction traditionally deals with the response of atoms, molecules and plasmas to an external light wave. However, the recent sustained technological p…
Collectively enhanced resonant photoionization in a multi-atom ensemble
Carsten Müller, Mihai A. Macovei, Alexander B. Voitkiv
Photoionization of an atom via interatomic correlations to N neighboring atoms may be strongly enhanced due to constructive interference of quantum pathways. The ionization proceed…
Relativistic three-body recombination with the QED vacuum
Huayu Hu, Carsten Müller
Electron-positron pair annihilation into a single photon is studied when a second free electron is present. Focussing on the relativistic regime, we show that the photon emitted in…
Resonant two-photon single ionization of two atoms
C. Müller, A. B. Voitkiv
Resonant two-photon ionization in a system consisting of two spatially well-separated atoms is studied. Due to two-center electron-electron correlations, the ionization may also pr…
