Radiation reaction in strong fields from an alternative perspective
Current classical theory of radiation reaction has several deficiencies such as "runaway solutions" and violation of causality. The Landau-Lifshitz approximation to the exact equation introduced by Lorentz, Abraham and Dirac is widely used, though questions remain regarding its domain of validity. …

Application of the resonant rotating wave approximation to the theory of resonant scattering
… scattering of light, including the effects of strong fields, is reported. The formulation is developed within the context of a new approximation, the resonant rotating wave approximation (RRWA). The RRWA is similar to the standard R\-lA, except that non-resonant rotating terms, as well as all …

Computation Methods for Parametric Analysis of Gravitational Wave Data
… why Post-Newtonian theory (meant for weak fields) works so well with strong fields of black hole mergers when it really should have failed [C. Will 2011]. Yunes and Pretorius gave another approach called parameterized post-Einsteinian (ppE) theory that uses negligible assumptions and …

Thermoelectric Magnetohydrodynamic Flows During Various Crystal Growth Processes With an Externally Applied Magnetic Field
… for Bridgman and float zone processes with strong fields. The azimuthal motion dominates the melt motion. As the magnetic field strength is increased from zero to large values, the azimuthal and meridional motions first increase from zero to maxima and then decay back toward zero for very …

Strong-field physics with ultrafast optical resonators
Light fields from modern high-intensity, femtosecond laser systems can produce electrical forces that rival the binding forces in atomic and solid-state systems. In this strong-field regime, conventional non-linear optics gives way to novel phenomena such as the production of attosecond bursts of …

THUNDERCLOUD ELECTRIC FIELD SOUNDINGS WITH INSTRUMENTED FREE BALLOONS
… precipitation. The corona record indicates that strong fields and charge of both polarities were encountered during the ascent. An abrupt decline in upwards directed corona current as the instrument passed through the cloud's upper surface may have resulted from a negative screening layer.

ANALYZING AND IMPROVING INITIAL DATA FOR BINARY BLACK HOLES
… holes adiabatically spiraling together. The strongest radiation is emitted at merger, where the strong fields and lack of symmetry require the use of fully numerical methods for solving Einstein's equations. Numerical simulations of binary black holes require the specification of initial data …

Energy transfer and localization in molecular crystals
… to different means of energy input: electric fields of various frequencies (100 − 4000<em>cm</em>−1) and strengths, and direct heating at various rates. It was found that non-equilibrium states can be created for short timescales when the energy input targets specific vibrations through the …

Untersuchungen der Wellenlängenabhängigkeit von Ionisationsprozessen von Xenon und Krypton in starken ultra-kurzen Laserfeldern
Die Beobachtung dynamischer Vorgänge steht nach wie vor im Mittelpunkt zahlreicher Forschungen auf vielen, <br>nicht nur physikalischen, Arbeitsgebieten. Die Beobachtung der <br>Dynamik eines Prozesses trägt oft wesentlich mehr zum Verständnis <br>der Physik bei als ausschließlich die Messung eines …

A multiscale study of atomic interactions in the electrochemical double layer applied to electrocatalysis
… a model of water dielectric saturation in the strong fields of the double layer. The water molecule dipole is computed in real space and Monte-Carlo simulation techniques are performed for the statistics of proton arrangement. DFT is seen to overestimate the permittivity of ice, confirming the …

Plasmon supported defect absorption in amorphous silicon thin film solar cells and devices
… lateral dimensions well below 100 nm accompany strong absorption and large electric field amplitudes in their vicinity. This is caused by the localized surface plasmon (LSP) resonances that are excited upon interaction of light with the nanostructures. By combining silver nanoparticles (Ag NPs) …
