Attosecond Transient Absorption Spectroscopy of doubly-excited states in helium
Luca Argenti, Christian Ott, Thomas Pfeifer +1
Strong-field manipulation of autoionizing states is a crucial aspect of electronic quantum control. Recent measurements of the attosecond transient absorption spectrum of helium dr…
Coherence-enhanced optical determination of the Th isomeric transition
Wen-Te Liao, Sumanta Das, Christoph H. Keitel +1
The impact of coherent light propagation on the excitation and fluorescence of thorium nuclei in a crystal lattice environment is investigated theoretically. We find that in the fo…
Coherent storage and phase modulation of single hard x-ray photons using nuclear excitons
Wen-Te Liao, Adriana Pálffy, Christoph H. Keitel
Coherent storage and phase modulation of x-ray single-photon wave packets in resonant scattering of light off nuclei is investigated theoretically. We show that by switching off an…
Resonance fluorescence in ultrafast and intense x-ray free-electron-laser pulses
S. M. Cavaletto, C. Buth, Z. Harman +4
The spectrum of resonance fluorescence is calculated for a two-level system excited by an intense, ultrashort x-ray pulse made available for instance by free-electron lasers such a…
Under-the-barrier dynamics in laser-induced relativistic tunneling
Michael Klaiber, Enderalp Yakaboylu, Heiko Bauke +2
The tunneling dynamics in relativistic strong-field ionization is investigated with the aim to develop an intuitive picture for the relativistic tunneling regime. We demonstrate th…
Quasiclassical approach to high-energy QED processes in strong laser and atomic fields
A. Di Piazza, A. I. Milstein
An approach, based on the use of the quasiclassical Green's function, is developed for investigating high-energy quantum electrodynamical processes in combined strong laser and ato…
