Laser Trapping of Circular Rydberg Atoms. [PDF]

open access: yesPhysical Review Letters, 2019
Rydberg atoms are remarkable tools for quantum simulation and computation. They are the focus of an intense experimental activity, mainly based on low-angular-momentum Rydberg states.

Die höchsten Oxidationsstufen der Seltenerdelemente und die Probleme mit den Praseodym(+5)‐Verbindungen

open access: yesAngewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Alle Seltenerdelemente bilden bekanntlich tri‐ und auch di‐valente Verbindungen. Wenige tetra‐valente Verbindungen sind auch bekannt; kürzlich wurden die ersten Moleküle und Kristalle mit Praseodym(+5) synthetisiert. Der hier definierte atomare Ionisations‐Quotient IQ legt nahe, dass Ln(+4)‐Verbindungen mit geeigneten Liganden für fast alle 4f‐Elemente

The Highest Oxidation States of the Rare‐Earth Elements and the Challenge of Praseodymium(+5) Compounds

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 1, 2 January 2026.
Rare Earth Elements are known to form tri‐ and also di‐valent compounds. A few tetra‐valent compounds are also known, and recently the first molecules and crystals with Praseodymium(+5) were synthesized. By defining the atomic Ionization Quotient IQ, Ln(+4) compounds with suitable ligands appear possible for almost all 4f elements, while Pr(+5) may ...

Quantum GraviElectro Dynamics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Effect of finite detection efficiency on the observation of the dipole-dipole interaction of a few Rydberg atoms

open access: yes, 2007
We have developed a simple analytical model describing multi-atom signals that are measured in experiments on dipole-dipole interaction at resonant collisions of a few Rydberg atoms.

Analysis of Methyl Substitution in Phenolic Compounds as Potential Biofuel Additives: From Solid‐State Description to Antioxidant Potential

open access: yesChemistrySelect, Volume 11, Issue 2, 15 January 2026.
The rising demand for renewable energy points to biodiesel as a viable fossil fuel alternative, yet its limited oxidative stability remains a challenge. This study reveals that methyl‐substituted hydroquinone derivatives exhibit enhanced antioxidant capacity, suggesting their promise as biofuel additives.

Observation of a resonant four-body interaction in cold cesium Rydberg atoms

open access: yes, 2011
Cold Rydberg atoms subject to long-range dipole-dipole interactions represent a particularly interesting system for exploring few-body interactions and probing the transition from 2-body physics to the many-body regime.

In Search of Structure’ Links Across Length Scales: Crossover Among Structural Motifs, Energetics, and Magic Systems in Subnanometer Transition Metals Clusters

open access: yesSmall Structures, Volume 7, Issue 1, January 2026.
Evolution of structural motifs of transition metal systems from tetramers and hexamers to bulk phases is studied. Clusters of transition metal (TM) elements are becoming increasingly important in our daily lives for a wide ensemble of applications in catalysis and bio‐fields, for health, energy and environmental problems.
