DPG Spring Meetings 2025

In March 2025, a large part of our working group attended the spring meetings of the German Physical Society (DPG) in Bonn (Atoms, Molecules, Quantum Optics and Photonics section) and Regensburg (Condensed Matter section), to which they contributed a large number of presentations and posters.

New Bachelor's degrees

In the last weeks, several of our bachelor students successfully defended their theses.

Andreas Anschütz, Charakterisierung und statistische Bewertung von Signalen eines CsTe-Detektors.

Leon Schwarz, Analyse elektronischer Strukturen und opimaler Messbedingungen für Photoeletronen-Zirkulardichroismus mit resonanten Auger-Elektronen.

Fabian Loibersbeck, Bestimmung der lateralen Quanteneffizienz eines Cäsiumtellurid-Detektors mittels Elektronenstoß-induzierter Fluoreszenzspektroskopie.

Christopher Wilke, Kalibrierung von Spektren aufgenommen mit einem Variable Line Spacing Grating Lumineszenz Spektrometer.

Joel Herrmann, Spektroskopische Untersuchung der Lumineszenz von Nukleotiden in wässriger Lösung nach Innerschalenionisation durch Synchrotronstrahlung.

Aaron Nyerges, Design Study on Photon Induced Fluorescence Spectroscopy Interaction Chambers and Cells.

Congratulations to all of you!

AIM Conference in Bressanone

From 09. - 12.02.2025 Jonas Bugase and Yahya Shubbak participated in the 5th AIM conference (Advances in Magnetics) in Bressanone (Italy). Jonas Bugase presented a talk entitled "Controlled transport of magnetic cuboidal particles in dynamic potential energy landscapes for lab-on-chip applications", Yahya Shubbak presented "Magnetophoretic distinction of differently surface-functionalized magnetic microparticles by close-to-surface transport in a quiescent liquid".
