Phenomenological Quantum-Electrodynamics
Physical Review, 1948 The quantization of the pure radiation field in a uniformly moving refractive medium is carried through both in the Hamiltonian and in the symmetrical four-dimensional form. The total energy and momentum are diagonalized. For a medium velocity larger than $\frac{c}{n}$ there occur photons with negative energy.

Double Helical Plasmonic Antennas
Advanced Functional Materials, EarlyView.Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Variational quantum electrodynamics [PDF]
Physical Review D, 2014 A variational method is discussed, based on the principle of minimal variance. The method seems to be suited for gauge interacting fermions, and the simple case of quantum electrodynamics is discussed in detail. The issue of renormalization is addressed, and the renormalized propagators are shown to be the solution of a set of finite integral equations.

Advanced Functional Materials, EarlyView.This work presents a novel sensing platform using metallo‐dielectric cryosoret nano‐assemblies and lossless photonic crystals to overcome limitations of conventional plasmonic biosensors. The hybrid system enhances both electric and magnetic field interactions, enabling amplified fluorescence, ultralow detection limits, and prism‐free, objective‐free ...

Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals
Advanced Functional Materials, EarlyView.In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

Advanced Functional Materials, EarlyView.This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...
