Rectification of Bacterial Diffusion in Microfluidic Labyrinths

Frontiers in Physics, 2019
In nature as well as in the context of infection and medical applications, bacteria often have to move in highly complex environments such as soil or tissues.

Nonlinear Transmission of Strong THz‐Electric Fields Through Thin Gold Films

Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.
Gold is is the prime metal for imaging THz radiation. This study demonstrates that the interaction of strong THz pulses with gold becomes nonlinear at certain peak THz‐electric field strengths. The strong fields change the electron density of states which contributing to the absorption of the propagating THz pulse.

Non-thermal electrons open the non-equilibrium pathway of the phase transition in FeRh

Communications Physics
The optical excitation of metals initially creates short-lived non-Fermi distributions of the electrons. The electrons and holes excited far above and below the Fermi level quickly relax to hot Fermi-distributions that subsequently cool via electron ...

N‐Heterocyclische Carbene auf einem III‐V‐Halbleiter: Von Kettenbildung zu geordneten Monolagen

Angewandte Chemie, Volume 137, Issue 46, November 10, 2025.
Die Funktionalisierung von GaAs, einem III‐V‐Halbleiter, mit N‐heterocyclischen Carbenen wird in einem multidisziplinären experimentellen und theoretischen Ansatz demonstriert. Es werden geordnete Monolagen erreicht, die aus Ketten von Molekülen bestehen, welche kovalent an die Oberfläche gebunden sind und die Oberflächeneigenschaften stark verändern ...

Ist Phenylnitren ein fehlendes Bindeglied in der Bildung polyzyklischer aromatischer Stickstoffheterozyklen?

Angewandte Chemie, Volume 137, Issue 31, July 28, 2025.
Ein neuer Bildungsweg für polyzyklische aromatische Stickstoffheterozyklen (PANH) wurde gefunden. Die Reaktion von Phenylnitren mit dem Propargylradikal führt zu Chinolin und belegt, dass Nitrene geeignete Vorläufer zum Einbau von Stickstoffheteroatomen sind.

Ultrafast lattice response of photoexcited thin films studied by X-ray diffraction

Structural Dynamics, 2014
Using ultrafast X-ray diffraction, we study the coherent picosecond lattice dynamics of photoexcited thin films in the two limiting cases, where the photoinduced stress profile decays on a length scale larger and smaller than the film thickness. We solve

Constraining the Natural MSSM through tunneling to color-breaking vacua at zero and non-zero temperature

Physics Letters B, 2014
We re-evaluate the constraints on the parameter space of the minimal supersymmetric standard model from tunneling to charge- and/or color-breaking minima, taking into account thermal corrections.

Entropy production in non-reciprocal polar active mixtures

New Journal of Physics
The out-of-equilibrium character of active systems is often twofold, arising from both the activity itself and from non-reciprocal couplings between constituents.

Warme dichte Materie in Natur und Labor: Ein ungewöhnlicher Materiezustand

Physik in unserer Zeit, Volume 56, Issue 4, Page 198-204, July 2025.
Warme dichte Materie rückt immer mehr in den Fokus, nicht nur in der Physik und Astronomie, sondern auch in den Ingenieurswissenschaften und sogar der Politik. Es handelt sich um interessante, aber auch komplizierte Zustände von Materie, die unser Verständnis ihrer Funktionsweise herausfordern.

Hadron Spectroscopy with lattice QCD: Challenges and opportunities [PDF]

EPJ Web of Conferences
Ongoing challenges in computing the spectrum of hadronic resonances and shallow bound-states from lattice QCD are reviewed. Since such states are identified as poles in the scattering matrix, nearby non-analyticities must be treated to analytically ...
