Potassium‐Ligand Cooperation Facilitated Chemical Bond Activation and Catalytic Hydrogenation
Angewandte Chemie, Volume 138, Issue 28, 6 July 2026.A new strategy for alkali metal‐mediated catalysis based on metal–ligand cooperation (MLC) is presented. Potassium pincer complexes exhibit remarkable reactivity toward a range of molecules via an unprecedented potassium–ligand cooperative mechanism. This reactivity enables potassium‐catalyzed hydrogenation, providing efficient reduction of ketones and

Engineering thermal reservoirs for ultracold dipole–dipole-interacting Rydberg atoms
New Journal of Physics, 2018 We consider an open quantum system of ultracold Rydberg atoms. The system part consists of resonant dipole–dipole-interacting Rydberg states. The environment part is formed by ‘three-level atoms’: each atom has a ground state, a short-lived excited state,

Digital–Analog Quantum Simulation and Computing: A Perspective on Past and Future Developments
Advanced Computing, Volume 1, Issue 1, December 2026.In the past decade, the paradigm of digital–analog quantum technologies has emerged, which proposes to combine the best of both paradigms: large analog blocks, provided by native interactions of the employed quantum platform, enabling scalability, combined with digital gates, allowing for more versatility and, ultimately, universality.

ChemPhysChem, Volume 27, Issue 19, 14 October 2026.In this study, the ability of M2 clusters (M = Cu, Ag, and Au) to form noncovalent homodimers/homotrimers has been evaluated at the RI‐PBE0‐D4/def2‐TZVPD level of theory. The results have been complemented with QTAIM, NCIplot, and EDA analyses, which helped to shed light on the physical nature of these unconventional noncovalent contacts. In this study,

Excited state spatial distributions in a cold strontium gas [PDF]
, 2012 This thesis describes the development of a new technique for measuring the spatial distribution of Rydberg atoms in a cold strontium gas. Strontium atoms are cooled and trapped in a magneto-optical trap and coherently excited to Rydberg states in a two ...

Dipolar Rydberg-atom gas prepared by adiabatic passage through an avoided crossing
New Journal of Physics, 2015 The passage of cold cesium 49S $_{1/2}$ Rydberg atoms through an electric-field-induced multi-level avoided crossing with nearby hydrogen-like Rydberg levels is employed to prepare a cold, dipolar Rydberg atom gas.

Optical Basicity of Glasses: Review and Application in Nuclear Glass Formulation
International Journal of Applied Glass Science, Volume 17, Issue 4, October 2026.A self‐consistent set of optical basicity (OB) values was compiled and evaluated for 95 binary oxides using electronegativity, ionic–covalent, and optical‐property approaches, providing a robust basis for estimating the basicity of complex compounds and glasses.

New Journal of Physics, 2020 We present distinct antiblockade features of strongly interacting 64 D _5/2 Rydberg atoms employing a two-color excitation scheme. The first color (pulse A) is set to resonantly excite a few seed Rydberg atoms, each of which establishes a blockade region

Stochastic switching in the Rydberg atomic ensemble
Optics Express, 2020 We demonstrated stochastic switching in a bistable system implemented with the Rydberg atomic ensemble, which is realized by cascaded Rydberg excitation in a cesium vapor cell. Measurement of Rydberg state’s population by means of the electromagnetically induced transparency allows us to investigate the nonlinear behavior in Rydberg atomic ensemble ...
