Statistical properties of a free-electron laser revealed by the Hanbury Brown and Twiss interferometry
O. Yu. Gorobtsov, G. Mercurio, G. Brenner +12
We present a comprehensive experimental analysis of statistical properties of the self-amplified spontaneous emission (SASE) free-electron laser (FEL) FLASH at DESY in Hamburg by m…
WavePacket: A Matlab package for numerical quantum dynamics. I: Closed quantum systems and discrete variable representations
Burkhard Schmidt, Ulf Lorenz
WavePacket is an open-source program package for the numerical simulation of quantum-mechanical dynamics. It can be used to solve time-independent or time-dependent linear Schrödin…
Revealing three-dimensional structure of individual colloidal crystal grain by coherent x-ray diffractive imaging
A. G. Shabalin, J. -M. Meijer, R. Dronyak +12
We present results of a coherent x-ray diffractive imaging experiment performed on a single colloidal crystal grain. The full three-dimensional (3D) reciprocal space map measured b…
Theoretical study of electronic damage in single particle imaging experiments at XFELs for pulse durations 0.1 - 10 fs
O. Yu. Gorobtsov, U. Lorenz, N. M. Kabachnik +1
X-ray free-electron lasers (XFELs) may allow to employ the single particle imaging (SPI) method to determine the structure of macromolecules that do not form stable crystals. Ultra…
Intensity interferometry of single x-ray pulses from a synchrotron storage ring
A. Singer, U. Lorenz, A. Marras +10
We report on measurements of second-order intensity correlations at the high brilliance storage ring PETRA III using a prototype of the newly developed Adaptive Gain Integrating Pi…
Ptychography imaging of the phase vortices in the x-ray beam formed by nanofocusing lenses
D. Dzhigaev, U. Lorenz, R. Kurta +11
We present the ptychography reconstruction of the x-ray beam formed by nanofocusing lenses (NFLs) containing a number of phase singularities (vortices) in the vicinity of the focal…
Hanbury Brown and Twiss interferometry at a free-electron laser
A. Singer, U. Lorenz, F. Sorgenfrei +11
We present measurements of second- and higher-order intensity correlation functions (so-called Hanbury Brown and Twiss experiment) performed at the free-electron laser (FEL) FLASH…
Impact of ultrafast electronic damage in single particle x-ray imaging experiments
U. Lorenz, N. M. Kabachnik, E. Weckert +1
In single particle coherent x-ray diffraction imaging experiments, performed at x-ray free-electron lasers (XFELs), samples are exposed to intense x-ray pulses to obtain single-sho…
Dynamics of colloidal crystals studied by pump-probe experiments at FLASH
R. Dronyak, J. Gulden, O. M. Yefanov +20
We present a time-resolved infrared (IR) pump and extreme-ultraviolet (XUV) probe diffraction experiment to investigate ultrafast structural dynamics in colloidal crystals with pic…
"Centrifugal fragmentation" in the photodissociation of H2+ in intense laser fields
Michael Fischer, Ulf Lorenz, Burkhard Schmidt +1
By means of quantum-dynamical and classical trajectory calculations of H2+ photodissociation in strong laser fields, it is shown that for certain combinations of pulse durations an…
