Atomistic insights into surface stability and reactivity at solid/liquid interfaces from first principles calculations
Speaker:Mira Todorova (Max-Planck-Institut für Eisenforschung GmbH Computational Materials Design, Düsseldorf/Germany)
Abstract:Solid/liquid interfaces are at the heart of many problems of practical importance, be it battery materials, electro-catalysis or corrosion. A systematic improvement of any of these processes requires understanding of the processes occurring at such interfaces. Central to such an understanding is the identification of the structures forming at the surface of the solid immersed in an aqueous electrolyte, but our understanding of the role the electrolyte plays in shaping these structures is limited. It is furthermore essential to understand how a surface evolves under the influence of changing environmental conditions, such as an applied bias voltage, and unravel the elementary steps of the ensuing reactions. Ab initio modelling using density functional theory (DFT) has proven immensely successful in providing atomistic insight into various questions of materials science, but its applicatio

Imaging with ion beams at MedAustron
Speaker:Dr. Albert Hirtl (Atominstitut, TU Wien)
Abstract:Ion beam therapy with its advantageous property to selectively irradiate tumours, while sparing healthy tissue, has become an increasingly used method for cancer treatment in many facilities around the globe. For accurate dose delivery, the computer-assisted treatment planning process is an essential part requiring appropriate imaging of the tumour region and the surrounding structures. The current standard in radiation therapy is... The aim of this talk is to report on ongoing preparation work for establishing tomography with ion beams at MedAustron. Additionally, an overview of the infrastructure available for non-clinical research at MedAustron will be given. [for the complete abstract please visit: https://indico.smi.oeaw.ac.at/event/266/]

Calabi-Yau geometry from supersymmetric gauge theory
Speaker:Johanna Knapp (Univ. Wien)
Abstract:Calabi-Yau spaces play an important role in compactifications of string theory from ten to four dimensions. In this talk I will show how Calabi-Yaus can be constructed and analyzed by making use of a supersymmetric gauge theory in two dimensions – the gauged linear sigma model. After introducing the basic concepts and examples, I will give an overview of recent applications.

All-oder calculations for PDFs determination
Speaker:Simone Marzani (University of Genoa)
Abstract:I discuss the inclusion of the resummation in the context of the determination of parton distribution functions (PDFs). In particular, I present PDFs fits that are obtained including the resummation of threshold logarithms and high-energy logarithms, leading to a more reliable description of the large- and small-x regions of phase space. Specifically, I show how the PDF fit with small-x resummation provide strong evidence of BFKL dynamics in inclusive HERA data.
