Relativistic Lindblad description of the electron's radiative dynamics
Andre G. Campos, Karen Z. Hatsagortsyan, Christoph H. Keitel
An effective model for describing the relativistic quantum dynamics of a radiating electron is developed via a relativistic generalization of the Lindblad master equation. By incor…
Dark-fringe interferometer with dynamic phase control for Mössbauer science
Miriam Gerharz, Dominik Lentrodt, Lars Bocklage +10
Interference is a powerful tool for measuring and control. In Mössbauer science, interference effects are essential to most applications, due to the coherent scattering nature. How…
Single-shot sorting of Mössbauer time-domain data at X-ray free-electron lasers
Miriam Gerharz, Willi Hippler, Berit Marx-Glowna +28
Mössbauer spectroscopy is widely used to study structure and dynamics of matter with remarkably high energy resolution, provided by the narrow nuclear resonance line widths. Howeve…
Excitation of narrow x-ray transitions in thin-film cavities by focused pulses
Dominik Lentrodt, Christoph H. Keitel, Jörg Evers
A method to compute the excitation of narrow transitions at hard x-ray energies by short focused x-ray pulses is developed. In particular, the effect of thin-film cavities on the p…
Towards nonlinear optics with Mössbauer nuclei using x-ray cavities
Dominik Lentrodt, Christoph H. Keitel, Jörg Evers
Strong excitation of nuclear resonances, particularly of Mössbauer nuclei, has been a longstanding goal and the advance of novel x-ray sources is promising new options in this rega…
Nonspreading relativistic electron wavepacket in a strong laser field
Andre G. Campos, Karen Z. Hatsagortsyan, Christoph H. Keitel
A solution of the Dirac equation in a strong laser field presenting a nonspreading wave packet in the rest frame of the electron is derived. It consists of a generalization of the…
