On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media

open access: yesChemistry – A European Journal, Volume 32, Issue 21, 1 June 2026.
This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...

Dimensionality‐Driven Emerging Phenomena in Hybrid Metal Halides

open access: yesSmall Structures, Volume 7, Issue 6, June 2026.
Emergent Phenomena Governed by Octahedral Connectivity and Dimensionality. Hybrid metal halides are unique among semiconductors in that their inorganic octahedral networks can be rationally assembled in 3D, 2D, 1D, and 0D forms, enabling dimensionality to assist as a powerful control knob over structure, electronic properties, excitations, and ...

QUASI-LANDAU STRUCTURE OF DIAMAGNETIC HELIUM RYDBERG ATOMS

open access: yes, 1993
Diamagnetism in helium Rydberg atoms is studied near the ionisation threshold using constant scaled-energy laser spectroscopy. Quasi-Landau resonances in the Fouriertransform of the energy spectrum are explained using the classical periodic-orbit theory.

Jupiter's Auroral Ionosphere: Hybrid Monte Carlo, Auroral Spectrum and Conductivity Modeling

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present a new model of auroral precipitation and associated phenomena at Jupiter, called the Jupiter Auroral Ionosphere Code (JAIC). The hybrid model follows the primary electron population using a Monte Carlo code that runs on a GPU, and computes the contribution of the secondaries using a two‐stream approximation.

Coherent Excitation Transfer in a Spin Chain of Three Rydberg Atoms

open access: yes, 2015
We study coherent excitation hopping in a spin chain realized using highly excited individually addressable Rydberg atoms. The dynamics are fully described in terms of an XY spin Hamiltonian with a long range resonant dipole-dipole coupling that scales ...

Strong Plasmon–Exciton Coupling Tuned by Corner Etching of Gold Nanocubes and Nanotriangles

open access: yesAdvanced Optical Materials, Volume 14, Issue 18, 15 May 2026.
Systematic etching of gold nanocubes (AuNCs) and nanotriangles (AuNTs) reveals how nanoparticle morphology governs plasmon–exciton strong coupling. While rounding the corners of AuNCs weakens their coupling, triangular geometries robustly preserve deep strong coupling.

EXCITATION OF Zn ATOMS TO THE 4snf RYDBERG STATES

open access: yesRadio Physics and Radio Astronomy, 2014
A new two-stage scheme of laser excitation of Zn atoms to the 4snf Rydberg states is presented. A modification of the laser-microwave spectrometer of the Institute of Radio Astronomy intended for recording of Rydberg spectra of Zn atoms is described.

Enhanced Energy Transfer from a Metal–Organic Framework to a Highly Confined Organic Phosphorescent Dye

open access: yesAdvanced Science, Volume 13, Issue 30, 28 May 2026.
A phosphorescent dye was designed to fit in a hand‐to‐glove fashion into the 1D‐pore channels of MIL‐68(In). We synthesized MIL‐68(In) as powder and thin films, loaded the dye into the pores with controlled packing, and found that the phosphorescence and quantum yield are enhanced.

Rydberg Atoms for Quantum Information. [PDF]

open access: yes, 2010
I examine interactions between ensembles of cold Rydberg atoms, and between Rydberg atoms and an intense, optical standing wave. Because of their strong electrostatic interactions, Rydberg atoms are prime candidates for quantum information and quantum ...
