Dr. Matthiase Kleine-Boymanna (ION TOF, Germany)

The M6 is the latest generation of high-end TOF-SIMS instruments developed by IONTOF. Its design guarantees superior performance in all fields of SIMS applications. New ground-breaking ion beam and mass analyser technoligies make the M6 the benchmark in SIMS instrumentation and the ideal tool for industrial and academic research.

Leonid Sandratskii (MPI Halle & MFF UK)

The purpose of the work is to gain deeper insight into microscopic formation of the Dzyaloshinckii-Moriya interaction (DMI). We suggest a new method of calculation of the spiral structures with account for the spin- orbit coupling (SOC), based on application of the generalized Bloch theorem and generalized Bloch functions. The calculations are performed for the Co/Pt bilayer. The physical process of the DMI formation is connected with the difference in the hybridization of the Co and Pt states for q and -q spirals under the influence of the SOC and broken spatial inversion.

Georgios Loukes-Gerakopoulos (Astronomický ústav AV ČR, Praha)

Abstrakt: In this talk three different studies we have undertaken to address cosmological issues, like dark energy, will be presented and their results will be discussed. In these studies we have tried to remain model agnostic as much as possible. In particular, our first study (arxiv:1902.11051) concerns a cosmic fluid obeying rest-mass conservation of unspecified equation of state (EoS) in an unspecified background assuming just that the fluid's speed of sound is positive and less than the speed of light. Our second study (arXiv:2001.00825) performs a dynamical analysis of a barotropic...

Benoit Famaey (Observatoire astronomique de Strasbourg)

Abstrakt: While there is clear observational evidence for a new degree of freedom behaving as a non-baryonic collisionless dust fluid on large scales, there is no such solid evidence on galaxy scales. We point out that, on the contrary, the observational evidence for an intimate connection between the baryonic surface density and the total gravitational field in spiral galaxies, highlighted by the success of Modified Newtonian Dynamics (MOND) at reproducing observations, presents a fine-tuning problem for collisionless dark matter at these scales. We then assess how well MOND performs at...
