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.

Mechanism of Fixed Pattern Noise of Micro‐Channel Plate Focusing on Cross‐Section of Single Channel

Advanced Electronic Materials, Volume 11, Issue 9, June 2025.
The movement of secondary electrons to the phosphor screen after avalanche in microchannel plate (MCP) is influenced by the single channel cross‐sectional shape. The secondary electron beam emitted from MCP channels with different cross‐sectional shapes affects the energy and position upon striking the phosphor screen, directly impacting FPN (Fixed ...

Observation of Odderon effects at LHC energies: a real extended Bialas–Bzdak model study

European Physical Journal C: Particles and Fields, 2021
The unitarily extended Bialas–Bzdak model of elastic proton–proton scattering is applied, without modifications, to describe the differential cross-section of elastic proton–antiproton collisions in the TeV energy range, and to extrapolate these ...

Antiproton-deuteron annihilation at low energies

, 2000
Recent experimental studies of the antiproton-deuteron system at low energies have shown that the imaginary part of the antiproton-deuteron scattering length is smaller than the antiproton-proton one.

Extremophilic Microorganisms as a Source of Emerging Enzymes for the Food Industry: A Review

Food Science &Nutrition, Volume 13, Issue 1, January 2025.
Enzymes such as amylases, lipases, proteases, xylanases, laccases, pullulanase, chitinases, pectinases, esterases, isomerases, and dehydrogenases could be derived from extremophilic organisms like thermophiles, psychrophiles, acidophiles, alkaliphiles, and halophiles. These enzymes or extremozymes are applicable in the production of safe foods (such as

Production of antihydrogen at reduced magnetic field for anti-atom trapping [PDF]

, 2008
We have demonstrated production of antihydrogen in a 1$,$T solenoidal magnetic field. This field strength is significantly smaller than that used in the first generation experiments ATHENA (3$,$T) and ATRAP (5$,$T).

Extrem neutronenreicher Sauerstoffkern

Physik in unserer Zeit, Volume 56, Issue 1, Page 38-44, January 2025.
Die Sauerstoffatome in unserer Luft haben fast immer acht Protonen und acht Neutronen. Unter extremen Bedingungen, wie in Neutronensternen, kann aber Sauerstoff mit bis zu 16 Neutronen existieren. Einem internationalen Forschungsteam ist es gelungen, den neutronenreichsten Sauerstoffkern 28O mit sogar 20 Neutronen an der Forschungsanlage RIKEN in Japan

Charmonium production in p̄-induced reactions on nuclei

EPJ Web of Conferences, 2014
The production of charmonia in the antiproton-nucleus reactions at plab = 3 − 10 GeV/c is studied within the Glauber model and the generalized eikonal approximation. The main reaction channel is charmonium formation in an antiproton-proton collision. The

Polarization analysis of p̄ produced in pA collisions [PDF]

EPJ Web of Conferences, 2019
A quite simple procedure for the generation of a polarized antiproton beam could be worked out if antiprotons are produced with some polarization. In order to investigate this possibility measurements of the polarization of produced antiprotons have been
