Title: Atomistic spin dynamics and beyond
Speaker: Rosemary Jones, MAX IV Laboratory, Lund, Sweden
Abstract:
X-ray photoelectron spectroscopy, XPS, is a particularly powerful technique to probe surface reactions and chemistry. Ambient pressure XPS, APXPS, allows us to follow the evolution of surface species in real time and under ‘real’ conditions. At the APXPS end station of the SPECIES beamline, Max IV, we are pushing the capabilities of in situ and operando APXPS measurements with specially designed reaction cells for both ALD and catalytic research. In particular the ALD cell has allows chemical reactions to be followed during pulses of reactants, giving a much deeper insight into reaction mechanics.
This talk will take you through case studies from depositions of high-k oxides and how we can understand the ALD process in detail from AP-XPS data. We marry the surface sensitivity of XPS and the self-limiting controlled reactions to probe ALD chemistry. I will detail

Title: Quantum theory and mathematics. A 100-year success story
Speaker: Christoph Schweigert, University of Hamburg, Germany
Abstract:
The year 2025 marks the 100th anniversary of the papers by Heisenberg, Schrödinger, and Born-Jordan, which laid thefoundations of modern quantum mechanics. In recognition of these seminal papers, UNESCO has declared 2025 theInternational Year of Quantum Science and Technology.
In this talk, we will explore the interplay between quantum theories and mathematics. Through several examples, we willshow that mathematics provides crucial technology for the study of quantum theories and how quantum theories stimulate the development of new mathematics.
