An evaluation of charged pion polarizability using correlation functions measured on a 16 3 × 24 lattice in the context of the Das, Mathur, Okubo (DMO) sum rule is carried out. The calculation is limited to the so-called intrinsic part of the polarizability. This contribution, equivalent to a Eu-clidean time integral over vector and axial vector momentum-differentiated propagators, is evaluated...

Solutions for simple, canonical problems are important in electromagnetics, because they can be often utilized in more complicated problems. This thesis consists of analyses of some basic canonical objects and fundamental principles of electromagnetic theory. One of the fundamental objects analyzed in this thesis is an ellipsoid, and especially a layered ellipsoid. Although it is a basic and cl...

Aims & Scope The major goal of the JCMSE is the publication of new research results on computational methods in sciences and engineering. Common experience had taught us that computational methods originally developed in a given basic science, e.g. physics, can be of paramount importance to other neighbouring sciences, e.g. chemistry, as well as to engineering or technology and, in turn, to soc...

Using measured cross-sections and polarizability data, an empirical scaling law is extracted for the electron collision single-ionization cross-section maxima of neutral atoms. We found that cross sections scale linearly with target’s static polarizability. confirm this observation using our present three-body classical trajectory Monte Carlo simulations.

The aim of this work is to provide a physical model to relate the polarizability per unit cell of oligomers to that of their corresponding infinite polymer chains. For this we propose an extrapolation method for the polarizability per unit cell of oligomers by fitting them to a physical model describing the dielectric properties of polymer chains. This physical model is based on the concept of ...

We calculated the Raman spectrum of vitreous silica using a bond-polarizability model of which the parameters are derived from first-principles results on crystalline polymorphs of SiO2. By comparison with the experimental spectrum, we could give an estimate for the concentration of threeand four-membered rings[1]. We used a periodic model for vitreous silica consisting of corner-sharing tetrah...

Compton scattering results are used to probe proton structure via measurement of higher order polarizabilities. Values for α p E2 , β p E2 , α p Eν , β p Eν determined via dispersion relations are compared to predictions based upon chiral symmetry and from the constituent quark model. Extensions to spin-polarizabilities are also discussed.

Studying biological systems to determine structure has been performed by a number of analytical techniques, including electrospray ionization (ESI)/ion mobility spectrometry (IMS) with mass spectrometry (MS) detection. ESI/IMS/MS enables the determination of gas phase ionic molecular size and can be correlated to computational modeling for structural evaluation. In this study, a molecular model...
