We numerically solve the functional differential equations (FDE’s) of 2-particle electrodynamics, using the full electrodynamic force obtained from the retarded Lienard-Wiechert potentials and the Lorentz force law. In contrast, the usual formulation uses only the Coulomb force (scalar potential), reducing the electrodynamic 2-body problem to a system of ordinary differential equations (ODE’s)....

A simple procedure to incorporate one-loop quantum electrodynamic (QED) corrections into the generalized (Gatchina) nonlocal shape-consistent relativistic pseudopotential model is described. The pseudopotentials for Lu, Tl, and Ra replacing only inner core shells (with principal numbers $n\le 3$ two former elements 4$ latter one) are derived from solutions of reference atomic SCF problems with ...

Electrodynamic shakers are utilized in many experimental modal tests and general structural dynamic testing. The physical aspects of shaker, stinger and transducer setup can result in anomalies that are often misunderstood. Many times measurement artifacts related to mounting and dynamic coupling between shaker, stinger and test object can appear, affecting test results. This paper overviews so...

Infrared spectroscopy has emerged as a premier experimental technique to probe enigmatic effects arising from strong correlations in solids. Herewe report on recent advances in this area focusing on common patterns in correlated electron systems including transition metal oxides, intermetallics and organic conductors. All these materials are highly conducting substances but their electrodynamic...

The basic mechanisms of absorption THz range radiation in optically perfect LiGdF4 single crystals were studied using the broadband experimental data and dielectric response function analysis within harmonic oscillator model. polarized IR reflection spectra have allowed one to determine phonon contribution coefficient range, while transmission used obtain birefringence value effects various mul...

This paper studies satellite deorbit using electrodynamic tether (EDT) propulsion. Gaussian perturbation equations are used to model the orbital dynamics of EDT with environmental perturbations of electrodynamic force, aerodynamic drag and the effect of Earth’s oblateness. Differential equations for the induced voltage-current across EDT are derived and solved with boundary conditions determine...

A classical electrodynamic near field calculation for the interaction of a Drude oscillator molecular dipole with a rough metal surface is presented. Effects of electromagnetic coupling between surface bumps (assumed to be prolate hemispheroids) and the bulk metal are included. Fluorescence lifetimes are found to be two to four orders of magnitude smaller than those predicted for a flat plane i...
