| Superconductivity and antiferromagnetic correlations in Fe-based superconductors |
| Speaker: | Prof. Vladimir Tsurkan (Universität Augsburg) |
| Abstract: | In the first part of the talk a general introduction into the physical phenomena in several groups of novel Fe-based pnictide and chalgogenide superconductors will be given. The peculiarities of their crystal structure, magnetic and charge transport will be described.
The second part will be devoted to Rb-intercalated FeSe compounds. These compounds show fascinating coexistence of superconductivity and antiferromagnetic order. The details of growth of the single crystals will be described with relation to flux and Bridgman methods. The results of the structural and compositional characterization, SQUID, conductivity, and specific heat studies will be presented and discussed within the constructed phase diagramm of the Rb-Fe-Se system, which includes several phases with different magnetic and conductivity behavior.
Particular attention in the talk will be given to phase separation phenomena which provide an explanation for the coexistence of superconductivity and static antiferromagnetic order. The recent results of neutron scattering, Mössbauer spectroscopy, muon spin rotation, and nuclear magnetic resonance investigations which support the scenario of the phase separation in Rb0.8Fe1.6Se2 will be presented.
In the last part of the talk the new approach for Li-intercalation in FeSe which allowed to enhance the critical temperature up to 45 K will be discussed.

| Challenges in Numerical Simulations of Astrophysical Flows |
| Speaker: | Hannes Grimm-Strele (Uni Wien) |
| Abstract: | Abstract: Recent progress in multi-dimensional modelling of stars shows that the traditional one-dimensional approach is not sufficient to properly describe the structure of the star. Due to the wide range of length and time scales involved and the mixed hyperbolic-parabolic character of the governing equations these simulations are very difficult and expensive to carry out. Insufficient resolution gives qualitatively wrong results and numerical schemes of low order are not efficient. Boundary conditions have a large influence on the solution and must be designed suitably. Finally, the numerical grid must stay simple (i.e., structured) such that high-order methods are applicable, but must also offer some flexibility to cover more complicated domains. The simulation code ANTARES which is developed at the Faculty of Mathematics of the University of Vienna is designed to face these problems |
