Strong ultrafast nonlinear optical response from megaelectronvolt electrons in semiconductors
Abstract Understanding radiation–matter interactions on ultrafast timescales is essential for radiation detection technologies, particularly those requiring precise timing, such as plasma monitoring, synchrotron diagnostics and medical imaging. However, the detection of highly ionizing radiation is challenging due to the stochastic nature of the interactions, resulting in dispersed energy deposition.
Consus Crater on Ceres: Ammonium‐Enriched Brines in Exchange With Phyllosilicates?
1 Introduction The dwarf planet Ceres, the largest object (∼940 km diameter) in the main asteroid belt, orbits the Sun at a mean distance of ∼2.8 astronomical units, and is a survivor of the earliest period of Solar System formation. Information about its interior provides essential insights into the formation and evolution of volatile-rich planetary embryos which originated within the protoplanetary disc (e.g., Coradini et al., 2011).
Terahertz electric-field-driven dynamical multiferroicity in SrTiO3 - Nature
Abstract The emergence of collective order in matter is among the most fundamental and intriguing phenomena in physics. In recent years, the dynamical control and creation of novel ordered states of matter not accessible in thermodynamic equilibrium is receiving much attention1,2,3,4,5,6. The theoretical concept of dynamical multiferroicity has been introduced to describe the emergence of magnetization due to time-dependent electric polarization in non-ferromagnetic materials7,8.
Junge (5) vermisst: Sie suchen Mathis mit Drohnen, Heli und Tauchern
Saarbrücken – Sie setzen das volle Hightech-Programm ein, um den kleinen Mathis (5) zu finden. Der Junge war mit seiner Familie am Montag (2. Oktober) auf dem Spielplatz unterhalb des Staatstheaters. Als die Eltern ihn eine Sekunde aus den Augen ließen, verschwand er spurlos. Rund 100 Einsatzkräfte waren in Saarbrücken unterwegs. Polizei und Feuerwehr rückten mit drei Drohnen an, suchten mit Wärmebildkameras nach dem Jungen.

24 Stunden, in denen Putin die Kontrolle verlor ++ Der Söldner-Aufstand gegen Moskau
Dieser Tag wird in die Geschichte eingehen. Fast 24 Stunden lang war in Russland ein Militär-Putsch im Gange. Jewgeni Prigoschin (62), Chef der Wagner-Söldner, hat sich gegen den Kreml gestellt, Diktator Wladimir Putin (70) herausgefordert, brutal seine Macht demonstriert. Erst am Abend eines ereignisreichen Tages und 200 Kilometer vor der Hauptstadt blies er seinen Sturm auf Moskau ab. Wie es jetzt weitergeht – völlig ungewiss.
Rehybridization dynamics into the pericyclic minimum of an electrocyclic reaction imaged in real-time - Nature Communications
Abstract Electrocyclic reactions are characterized by the concerted formation and cleavage of both σ and π bonds through a cyclic structure. This structure is known as a pericyclic transition state for thermal reactions and a pericyclic minimum in the excited state for photochemical reactions. However, the structure of the pericyclic geometry has yet to be observed experimentally.
Formation of robust bound states of interacting microwave photons - Nature
|
Photons that propagate in vacuum do not interact with each other; however, many technological applications and the study of fundamental physics require interacting photons. Consequently, realizing quantum platforms with strong interactions between photons constitutes a major scientific goal10,11.

Atomic layer etching of ferroelectric hafnium zirconium oxide thin films enables giant tunneling electroresistance
No Access Appl. Phys. Lett. 120, 122901 (2022); https://doi.org/10.1063/5.0084636 The ferroelectric properties of hafnium oxide and zirconium oxide based thin films are promising for applications in low power electronics, such as ultra-thin ferroelectric tunneling devices. However, the amount of ferroelectric phase in the film depends on their polycrystalline morphology, which changes with film thickness.
Ultrafast electron dynamics in platinum and gold thin films driven by optical and terahertz fields
The advent of intense single-cycle terahertz (THz) radiation sources has opened new avenues for the exploration of the light–matter interaction with accessible electric fields of the order of MV/cm at photon energies in the meV range. With the emergence of these sources, it is now possible to study the THz-driven ultrafast dynamics of coupled degrees of freedom in condensed matter systems.1–51. C. Ruchert, C. Vicario, and C. P. Hauri, Opt. Lett. 37, 899 (2012). https://doi.org/10.1364/OL.37.0008992. M.
Ein Prozess-Integrierendes Clustertool für 2D-Materialsysteme: vom Einzelprozess zur Integration auf Waferlevel
2D materials are an upcoming class of materials for micro- and nanoelectronics due to their outstanding mechanical, optical, and electronic properties. They have attracted incredible interest both in the scientific and engineering communities. A reliable 2D technology in an industrial scale is yet to be demonstrated due to lack of suitable precursor chemistries, insufficient control of precise large-area monolayer growth, patterning processes or interface control up to now.

Ab initio analysis of magnetic properties of the prototype B20 chiral magnet FeGe
Abstract FeGe in the B20 phase is an experimentally well-studied prototypical chiral magnet exhibiting helical spirals, skyrmion lattices, and individual skyrmions with a robust length of 70 nm. While the helical spiral ground state can be verified by first-principles calculations based on density functional theory, this feature size could not be reproduced even approximately.

Weihnachtsschnäppchen: Welche Aktien nach den besinnlichen Tagen abzischen werden
Deutsche Konsumaktien: Weihnachtsschnäppchen: Welche Aktien nach den besinnlichen Tagen abzischen werden Fielmann, Zalando, Hawesko, CTS Eventim – an der Börse abgestraft. Zu Unrecht: Mit den Weihnachtszahlen kommt die Erholung. Die Arbeitslosigkeit ist auf einem mehrjährigen Tief, die Zahl der Beschäftigten ist mit mehr als 45 Millionen so hoch wie nie. Die Löhne und Renten steigen. Den (allermeisten) Deutschen geht es gut – und das wird auch in den nächsten Jahren so bleiben.
First Map of Residential Indoor Radon Measurements in Azerbaijan
This article describes results of the first measurements of indoor radon concentrations in Azerbaijan, including description of the methodology and the mathematical and statistical processing of the results obtained. Measured radon concentrations varied considerably: from almost radon-free houses to around 1100 Bq m?3. However, only ~7% of the total number of measurements exceeded the maximum permissible concentrations.
