Femtosecond transient soft X-ray absorption spectroscopy (XAS) is a very promising technique that can be employed at free-electron lasers (FELs) to investigate out-of-equilibrium dynamics for material and energy research. Here, dedicated setup X-rays available the Spectroscopy Coherent Scattering (SCS) instrument European Free-Electron Laser (European XFEL) presented. It consists of beam-splitting off-axis zone plate (BOZ) used in transmission create three copies incoming beam, which are...
Using ab initio calculations we reveal the nature of insulating phase recently found experimentally in monolayer 1T-NbSe2. We find soft phonon modes a large part Brillouin zone indicating strong-coupling charge-density-wave instability. Structural relaxation [Formula: see text] supercell reveals Star-of-David reconstruction with an energy gain 60 meV per primitive unit cell. The band structure distorted exhibits half-filled flat which is associated orbitals that are delocalized over several...
Common density-matrix functionals, the M\"uller and power functional, have been benchmarked for half-filled Hubbard dimer, which allows us to model bond dissociation problem transition from weakly strongly correlated limit. Unbiased numerical calculations are combined with analytical results. Despite well known successes of ground state is degenerate a one-dimensional manifold ferromagnetic solutions. The resulting infinite magnetic susceptibility indicates another qualitative flaw...
We discuss an open quantum system approach for the evaluation of reduced density-matrix functional in local approximation that approximates a correlated electron by impurity. Using resolvent approach, we calculate impurity density matrix and from this functional.
The aim of this tutorial is to analyze the equilibrium properties some simple but widely used quantum systems. canonical ensemble evaluate required here.
Data analysis applications for serial crystallography and single-particle imaging experiments at the European X-ray Free Electron Laser (EuXFEL) instrument SPB/SFX [1] range from near real-time data processing experimental optimisation to computationally intensive offline on stored long after experiment.Online tasks providing fast feedback during are integrated into EuXFEL-distributed control software Karabo [2].Alternatively, user groups can connect their own tools Karabo-Bridge, a client...
The advent of X-ray free-electron lasers (XFELs) has revolutionized fundamental science, from atomic to condensed matter physics, chemistry biology, giving researchers access X-rays with unprecedented brightness, coherence, and pulse duration. All XFEL facilities built until recently provided pulses at a relatively low repetition rate, limited data statistics. Here, we present the results first megahertz rate scattering experiments Spectroscopy Coherent Scattering (SCS) instrument European...
