ab initio R-matrix and MQDT investigation of low-lying Rydberg states of the HeH+ molecular ion

EPJ Web of Conferences, 2015
We report R-matrix calculations of low-lying Rydberg states of the hydrohelium molecular ion HeH+ corresponding to 1Δ and 3Δ symmetry. The calculations include states with principal quantum numbers 3 ≤ n ≤ 10.

Absorption Line Oscillator Strengths for the C 2Π(0)-A 2Σ+(0) Band of Nitric Oxide

The Astrophysical Journal, 2023
We have determined absorption oscillator strengths for rotational transitions of the C ^2 Π(0)- A ^2 Σ ^+ (0) band of NO, which has been detected in the upper atmosphere of Venus.

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.

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 ...

Toward The Use Of Rydberg States For State-selective Production Of Molecular Ions [PDF]

, 2014
The usual simplified view of Rydberg states of molecules as consisting of a single Rydberg electron loosely bound to a molecular ion core in a well-defined rotation-vibration state suggests an attractive possibility for state-selective production of ...

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

Electronic Structure and Electric Dipole Properties of the AgK Molecule: An Adiabatic and Diabatic Study

International Journal of Quantum Chemistry, Volume 126, Issue 21, November 5, 2026.
Ab initio adiabatic and diabatic calculations reveal the electronic structure of AgK, highlighting strong non‐adiabatic couplings, avoided crossings, and charge‐transfer effects. The resulting diabatic potentials and dipole moments provide benchmark data for spectroscopy and quantum dynamics of cold AgK molecules. ABSTRACT An ab initio investigation of

Cooperative Optical Non-linearity in a blockaded Rydberg Ensemble [PDF]

, 2011
This thesis describes the observation of a novel optical non-linearity mediated by the dipole-dipole interactions in a cold gas of Rydberg atoms. Electromagnetically induced transparency (EIT) is used to map the strong dipolar interactions onto an ...

Metastable doubly charged Rydberg trimers

Physical Review Research
We examine an effectively one-electron system with three positive nuclei composed of a ^{87}Rb^{*} Rydberg atom interacting with a pair of ^{87}Rb^{+} ions and predict the existence of metastable vibrationally bound states of ^{87}Rb_{3}^{2+}.
