Collective Electrodynamics I [PDF]

open access: yesProceedings of the National Academy of Sciences, 1997
Standard results of electromagnetic theory are derived from the direct interaction of macroscopic quantum systems; the only assumptions used are the Einstein–deBroglie relations, the discrete nature of charge, the Green’s function for the vector potential, and the continuity of the wave function.

Strong Coupling in Bulk Nanoplasmonic Nanoplatelet Perovskite Scintillators

open access: yesAdvanced Materials, EarlyView.
A bulk scintillating nanocomposite is engineered from CsPbBr3 nanoplatelets and Ag nanocubes to support exciton–plasmon strong coupling under X‐ray excitation. The resulting hybrid polaritonic states appear directly in radioluminescence, opening a route toward polariton‐enabled scintillator design beyond conventional Purcell enhancement.

FIX OF ELECTRODYNAMICS

open access: yes, 2022
Lorentz's statement is known that "... Heaviside and Hertz gave a clear and concentrated form to Maxwell's equations." At present, after Heaviside and Hertz, the applicability of Maxwell's equations to all phenomena of electrodynamics and electrical devices is indisputable.

Integrated fiber optical receiver reducing the gap to the quantum limit

open access: yesScientific Reports, 2017
Experimental results of a single-photon avalanche diode (SPAD) based optical fiber receiver integrated in 0.35 µm PIN-photodiode CMOS technology are presented. To cope with the parasitic effects of SPADs an array of four receivers is implemented.

Solar cycle variations in equatorial ionospheric zonal electric fields near sunrise

open access: yesEarth and Planetary Physics, 2023
In this study, we investigate the solar cycle dependence of the sunrise ionospheric zonal electric fields at the equator under geomagnetically quiet conditions.

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

open access: yesAdvanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Chirality in Optical Trapping and Optical Binding

open access: yesPhotonics, 2015
Optical trapping is a well-established technique that is increasingly used on biological substances and nanostructures. Chirality, the property of objects that differ from their mirror image, is also of significance in such fields, and a subject of much ...

Electrodynamics of Axial-Flow Rotary Blood Pumps

open access: yesIEEE Access, 2021
In this work, electric machine of implantable rotary blood pumps (RBPs) of axial-flow type was theoretically investigated. Electromagnetic coupling of rotor and stator in axial-flow RBPs was described with the Maxwell’s equations of the classical ...

Thermoplastic Dielectric Coatings for Flexible Electrodynamic Dust Shields: Structural and Functional Performance

open access: yesAdvanced Materials Interfaces, EarlyView.
Thermoplastic attachment is introduced as a scalable surface coating strategy to improve the durability and dielectric reliability of flexible electrodynamic dust shields. By embedding chemically modified reduced graphene oxide (CMrGO) electrodes within thermoplastic laminates, mechanical degradation, abrasion damage, and vacuum‐induced electrical ...

Pulsar Electrodynamics

open access: yesSymposium - International Astronomical Union, 1981
This paper briefly discusses the salient features of quasi-steady electrodynamics; that is to say it considers certain general properties of Maxwell's equations and their solutions when these equations are subjected to the constraint where ω is a constant angular frequency, ⊘ and t are the azimuthal angle and time, and the operators are applied only ...
