Vieles ist schlecht gelaufen in den letzten 35 Jahren. Die Folgen spüren wir jetzt. Und dennoch war und bleibt der 9. November 1989 ein magischer Moment.
Ich habe damals in #Flensburg gelebt und die Ereignisse von dort aus mitbekommen. Ich kann mich nur noch vage erinnern, aber ich habe staunend vor dem Fernseher gesessen.

Meine Nacht des Mauerfalls
Zeitzeugen aus Ost und West erzählen vom Mauerfall am 9.11.1989 – eine Nacht, die Geschichte schrieb und Deutschland veränderte. Eine ZDF-Doku.

Reversal of strain state in a Mott insulator thin film by controlling substrate morphology
The V2O3 phase diagram contains two insulating phases and one metallic phase with different lattice structures. The stability of these phases is very sensitive to pressure, offering a mechanism to tune phase transitions by inducing strain in thin films. The most studied source of strain is lattice mismatch between the film and the substrate. In this work, however, we find that the film/substrate thermal expansion mismatch can be made to play a dominant role by modifying the substrate morphology…

Effect of Deposition Pressure on the Superconductivity of Ti40V60 Alloy Thin Films
The growth and characterization of high quality superconducting thin films is essential for fundamental understanding and also for the use of these films in technological applications. In the present study, Ti40V60 alloy thin films have been deposited using DC magnetron co sputtering of Ti and V at ambient temperatures. The effect of deposition pressure on the film morphology, superconducting and normal state properties has been studied. Measurement of electrical resistance as a function of tem…

Electrode modified domain morphology in ferroelectric capacitors revealed by X-ray microscopy
Ferroelectric thin films present a powerful platform for next generation computing and memory applications. However, domain morphology and dynamics in buried ferroelectric stacks have remained underexplored, despite the importance for real device performance. Here, nanoprobe X-ray diffraction (nano-XRD) is used to image ferroelectric domains inside BiFeO3-based capacitors, revealing striking differences from bare films such as local disorder in domain architecture and partial polarization reori…

Probing the extent of WASP-52 b's atmosphere. High-resolution observations and 3D modeling insights
WASP-52 b is an inflated hot Jupiter with a large Roche lobe filling fraction, positioned in the hot Neptune desert. Previous in-transit observations of the helium triplet at 10833 A have reported a range of excess absorption values (1.5%-5.5%) and a lack of net blueshift relative to the planet's rest frame, distinguishing it from other escaping atmospheres. This study investigates the extent and morphology of material escaping from WASP-52 b, assessing whether its outflow resembles a stream-li…

Validation of the Following Streamer mechanism for SF6 breakdown induced by floating linear metal particles
A recently proposed Following Streamer mechanism (Feng et al. 2025 Phys. Rev. Applied 23 064039) seeks to explain how floating metal particles induce SF6 streamer breakdown in the combined gap. This mechanism is derived from a 2D axisymmetric fluid model, which has limitations in describing multiple streamer events in real-world 3D scenarios. To validate the Following Streamer mechanism, we experimentally investigate the discharge morphology of SF6 streamers induced by a floating linear metal p…

Morphology of Polarization States in Strained Ferroelectric Films
Ferroelectric thin films under epitaxial strain exhibit a variety of vortex-like topological polarization textures. To analyze them, we build on the Ginzburg-Landau-Devonshire framework and extend the previously introduced soft-domain approach. This formulation provides a compact variational theoretical description of polarization morphologies in strained PbTiO$_3$ films. It yields phase diagrams as a function of temperature, strain, and thickness, and clarifies the morphological structure of e…
