Target fabrication for laser-ion acceleration research at the Technological Laboratory of the LMU Munich

Matter and Radiation at Extremes, 2019
The Technological Laboratory of LMU Munich supplies various types of solid-state target for laser plasma experiments at the Centre for Advanced Laser Applications in Garching. Our main focus here is on the production of free-standing,

Spinfrustration bestimmt Stabilität und Reaktivität von metallorganischen Gerüstverbindungen mit dreieckigen Eisen(III)‐Oxo‐Clustern

Angewandte Chemie, Volume 137, Issue 41, October 6, 2025.
Konventionelle DFT kann den spinfrustrierten Grundzustand von MOFs mit dreieckigen Fe(III)‐Knoten nicht richtig beschreiben, was zu verzerrten Geometrien und falschen Vorhersagen führt. Mittels Flip‐Spin DFT identifizieren wir den echten Grundzustand von MIL‐101(Fe) und zeigen, wie magnetische Frustration die temperaturabhängige Adsorption von N2${\rm ...

Evolution of confined quantum scalar fields in curved spacetime. Part II

European Physical Journal C: Particles and Fields, 2021
We develop a method for computing the Bogoliubov transformation experienced by a confined quantum scalar field in a globally hyperbolic spacetime, due to the changes in the geometry and/or the confining boundaries.

Tunable Room‐Temperature Polaritons in the Very Strong Coupling Regime in Quasi‐2D Ruddlesden–Popper Perovskites

Advanced Optical Materials, Volume 13, Issue 30, October 24, 2025.
The study reports widely tunable room‐temperature exciton polaritons in quasi‐2D perovskite microcavities operating at the transition between strong and very strong coupling regimes. These experimental and theoretical insights explain the peculiar scaling behavior of the light–matter coupling in our tunable system, paving the way for future tunable ...

Instantaneous Normal Modes of Yukawa Liquids

Contributions to Plasma Physics, Volume 65, Issue 8-9, October 2025.
ABSTRACT The instantaneous normal mode (INM) approach, which extends the normal mode description of collective excitations in solids to liquids, is applied to strongly coupled, three‐dimensional Yukawa liquids. Based on data from Langevin dynamics simulations, we compute the instantaneous normal modes across a wide range of coupling and screening ...

Fluctuations and differential contraction during regeneration of Hydra vulgaris tissue toroids

New Journal of Physics, 2013
We studied regenerating bilayered tissue toroids dissected from Hydra vulgaris polyps and relate our macroscopic observations to the dynamics of force-generating mesoscopic cytoskeletal structures.

Non-hydrodynamic modes from linear response in kinetic theory [PDF]

EPJ Web of Conferences
Viscous hydrodynamics serves as a successful mesoscopic description of the QGP produced in relativistic heavy-ion collisions. In order to investigate, how such an effective description emerges from the underlying microscopic dynamics we calculate the ...

Das Trautonium: Des kleinen Elektromusikers Liebling

Physik in unserer Zeit, Volume 56, Issue 5, Page 244-245, September 2025.
Im 20. Jahrhundert wurden viele elektronische Musikinstrumente erfunden. Das Trautonium kam sogar in Alfred Hitchcocks „Die Vögel“ zum Einsatz. Zusammenfassung Das Trautonium wurde von Friedrich Trautwein 1930 vorgestellt. Dessen Prinzip basiert auf der Erzeugung eines sehr obertonreichen Grundklangs, der durch verschiedene Filter umformbar ist.

Pure Deep Red Electroluminescence in Mixed Phase Quasi‐2D Tin Iodide Perovskite Heterostructure

Small, Volume 21, Issue 38, September 25, 2025.
Mixed‐cation quasi‐2D tin iodide perovskites show promise for deep red to NIR LEDs. Despite forming mixed n = 1, 2, and ∞ phases, pure deep red electroluminescence (≈700 nm) from the n = 2 phase is achieved by tuning cation ratios. Selective charge transport and cascade energy transfer enable phase‐selective emission. Abstract Mixed cation quasi‐2D tin
