Radiative nonrecoil nuclear finite size corrections of order α(Zα)5 to the Lamb shift in light muonic atoms

Physics Letters B, 2017
On the basis of quasipotential method in quantum electrodynamics we calculate nuclear finite size radiative corrections of order α(Zα)5 to the Lamb shift in muonic hydrogen and helium.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
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

Narrow Linewidth Spontaneous and Lasing Emissions from Open‐Access Microcavity‐Embedded Perovskite Quantum Dots

Advanced Optical Materials, EarlyView.
Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.

Unveiling How Electric Fields Influence Electroluminescent Properties in Light‐Emitting Electrochemical Cells via Operando Optically Detected Magnetic Resonance

Advanced Optical Materials, EarlyView.
Electroluminescence‐detected magnetic resonance (ELDMR) is used to probe electron–hole pairs in light‐emitting electrochemical cells under operando conditions. The measurements reveal sweep‐dependent hysteresis linked to changes in the internal electric field, which governs recombination efficiency. These findings demonstrate the capability of ELDMR to

Quantum electrodynamical formulation of photochemical acid generation and its implications on optical lithography

ETRI Journal
The photochemical acid generation is refined from the first principles of quan-tum electrodynamics. First, we briefly review the formulation of the quantum theory of light based on the quantum electrodynamics framework to establish the probability of ...

Quantum Jumps in Amplitude Bistability: Tracking a Coherent and Invertible State Localization

Annalen der Physik, EarlyView.
A notable asymmetry is shown to characterize the bistable switching between macroscopic metastable states of light in the strong‐coupling limit of radiation–matter interaction. Transitions from the vacuum to a highly excited state correlate with a highly bunched sequence of emitted photons, while a downward switch to the vacuum involves a coherent ...

A Physically-Motivated Quantisation of the Electromagnetic Field on Curved Spacetimes

Entropy, 2019
Recently, Bennett et al. (Eur. J. Phys. 37:014001, 2016) presented a physically-motivated and explicitly gauge-independent scheme for the quantisation of the electromagnetic field in flat Minkowski space.
