Fiber-Coupled Ultra-High-Q Microresonators for Nonlinear and Quantum Optics [PDF]

, 2004
The ability to confine optical energy in small volumes for long periods of time is desirable for a number of applications, ranging from photonics and nonlinear optics, to fundamental studies in quantum electrodynamics.

Crucial Role of Magnetic Dipole and Anomalous Field Dependence in NiPS3

Small, EarlyView.
Torque magnetometry on the prototypical 2D anisotropic magnet NiPS3, together with relativistic density functional theory calculations, uncovers a distinct intrinsic magnetic anisotropy. The characteristic torque pattern, driven by a high‐field spin‐flop transition, reveals its magnetic response beyond standard XY or XXZ models and highlights the ...

From Nano‐ to Picocavities: The Role of Atomistic Features

Small Structures, Volume 7, Issue 10, October 2026.
Atomistic features strongly affect the plasmonic response of Ag and Au nano‐ and picocavities. By analyzing induced charge densities, electric field maps, and localization areas, the role of atomistic morphology in controlling field confinement and enhancement is revealed, establishing a direct structure–property relation between atomic‐scale features ...

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.

Offshell quantum electrodynamics

Journal of Physics: Conference Series, 2013
More than twenty years have passed since the threads of the `proper time formalism' in covariant classical and quantum mechanics were brought together to construct a canonical formalism for the relativistic mechanics of many particles. Drawing on the work of Fock, Stueckelberg, Nambu, Schwinger, and Feynman, the formalism was raised from the status of ...

Large Rabi Splitting Driven by Plasmon‐Enhanced Hybrid Anapole States in Si–Au–WSe2 Heterostructures

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
A silicon hybrid‐anapole microcavity coupled with a plasmonic array enables tripartite strong coupling with WSe2 excitons. Spatially extended field enhancement and coherent cavity–plasmon hybridization strengthen light–matter interactions, producing a giant 330 meV Rabi splitting at room temperature and offering a compact platform for low‐exciton ...

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 ...

Experimental and Computational Investigations of Surface Polaritons at Metal‐Oxide‐Semiconductor Interfaces

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
STEM‐EELS and full‐wave FDTD reveal electron‐driven surface‐polariton modes at buried Au/oxide/Si interfaces with 10 nm SiO2 or Al2O3 spacers. Extinction is dominated by non‐radiative absorption, while oxide permittivity shifts the resonance and controls evanescent‐field penetration across the spacer into silicon.

Probing Strong Coupling in Core–Shell Nanoparticles With Fast Electron Beams

physica status solidi (a), Volume 223, Issue 17, 9 September 2026.
An exact analytic formalism for evaluating electron‐energy loss and cathodoluminescence probabilities for core–shell nanoparticles explored by electron‐beam spectroscopies is derived. The formalism is exploited to understand strong exciton–plasmon and exciton–Mie mode coupling in nanophotonic architectures.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced 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
