Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Surface-modified interactions between Rydberg atoms [PDF]

open access: yes, 2021
Rydberg atoms are highly excited atoms with intriguing properties. In the framework of quantum electrodynamics, the internal dynamics of a Rydberg atom in front of a surface are investigated in fourth order perturbation theory.

Finite‐Time Protocols Stabilize Charging in Noisy Ising Quantum Batteries

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 9, September 2026.
A transverse‐field quantum Ising chain is charged as a quantum battery using finite‐time ramps, which suppress energy oscillations and stabilize charging compared to sudden quenches. When time‐correlated noise is introduced, the outcome depends entirely on the protocol: noise can either boost stored energy or improve efficiency, never both ...

Autler–Townes splitting in the trap-loss fluorescence spectroscopy due to single-step direct Rydberg excitation of cesium cold atomic ensemble

open access: yesAIP Advances, 2023
We experimentally investigate trap-loss spectra of the cesium 6S1/2(F = 4) → 71P3/2 Rydberg transition by combining the cesium atomic magneto-optical trap with the narrow-linewidth, continuously tunable 318.6 nm ultraviolet laser. Specifically, the atoms

High-order correction calculation for survival of Rydberg atoms in intense laser fields

open access: yesResults in Physics, 2021
Using a method based on the Magnus expansion, the survival of Rydberg atoms in intense laser fields is studied. Usually, for atoms in intense laser fields, effects beyond the electric dipole approximation need to be considered.

Drone Delivery Packing Problem on a Neutral‐Atom Quantum Computer

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 9, September 2026.
This research models the Drone Delivery Packing Problem as a battery‐constrained graph partitioning. We use Pasqal's Fresnel QPU to sample time‐feasible single‐drone schedules, with tunable delivery targets via hardware parameters, and enforce battery limits by greedy post‐processing.

Coherent control of Goos-Hänchen shift in a guided-wave surface plasmon resonance structure with Rydberg atoms

open access: yesResults in Optics, 2021
We proposed an effective and flexible scheme to achieve tunable giant Goos-Hänchen (GH) shift of reflected light in the configuration of guided-wave surface plasmon resonance with Rydberg atoms. With the super atom model of Rydberg atom due to the dipole

Dissecting the Electronic Factors Governing Phosphine Oxide Reduction With Silanes: A Computational Study

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 24, 21 August 2026.
Phosphine oxide reduction with silanes is governed by phosphine oxide distortion and silane interaction energies. In R3SiH silanes, NBO analysis reveals that n(O)→σ*(SiR) donation is distributed among several acceptor orbitals, whereas in Ph2RSiH silanes, small electronegative substituents directly bonded to silicon (RCl, OCN, OH) enhance the σ ...

Coherent atom-light interactions in multi-level systems [PDF]

open access: yes, 2009
This thesis presents work on experiments performed using electromagnetically induced transparency (EIT) in Rubidium vapour cells. Starting with a simple three-level Λ-system, extra complexity is introduced by adding an additional control beam. This makes

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

open access: yesChemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.
