Abstract:
The Marching On-In-Time (MOT) unstructured Partial Element Equivalent Circuit (PEEC) method for time domain electromagnetic problems is presented. The method allows the transient analysis of electrically large electromagnetic devices consisting of conductive, dielectric, and magnetic media coupled with external lumped circuits. By re-formulating PEEC following the Coulombian interpretation of magnetization phenomena and by using electric and magnetic vector potentials, the proposed approach allows for a completely equivalent treatment of electric and magnetic media and inhomogeneous and anisot

Abstract:
Boson star (BS) rotation is studied under Newtonian approximation. A Coulombian potential term is added as perturbation to the radial potential of the system without disturbing the angular momentum. The results of the stationary states of these ground state, first and second excited state are analyzed with the correction of Coulombian potential. It is found that the results with correction increased in the amplitude of oscillation of BS in comparison to potential without perturbation correction.

Abstract:
Exact solutions are found for the Dirac equation for a combination of Lorentz scalar and vector Coulombic potentials with additional non-Coulombic parts. An appropriate linear combination of Lorentz scalar and vector non-Coulombic potentials, with the scalar part dominating, can be chosen to give exact analytic Dirac wave functions. The method works for the ground state or for the lowest orbital state with l=j-½, for any j.

Abstract:
In this work, we study the time evolution of systems containing a large number of particles interacting via a $1/r$ binary interaction potential, such as Coulombian and self-gravitating systems. In particular, we study the effect on the dynamics of the Holtsmark-Chandrasekhar theory, which describes the static fluctuations of the total force field around the Vlasov mean-field. We derive these effects by developing a new perturbative theory using the fundamental representation of Statistical Mechanics :The BBGKY hierarchy. This leads to a modification of the Vlasov equation by an additional ter

Electrokinetic transport in nanofluidics has attracted many attentions in recent years due to its potential applications in biomedical analysis and energy conversion systems.

In this work, we develop an efficient molecular approach to simulate electrokinetic transport in nano-scale.

Abstract:
In an electrospray, large electric potentials are used to generate a spray of highly charged droplets. Colloidal dispersions, consisting of nanoparticles in a volatile solvent, can be atomized using electrospray. Printing occurs by directing the emitted droplets towards a target substrate. The solvent evaporation is rapid and dry nanoparticles are produced before reaching the surface. Electrospray imparts an excess electric charge on to the emitted particles. The mutual coulombic interaction between the particles governs their transport and ultimately the microstructure of the printed deposit.

One such application is pumping and transport of dielectric fluids in micropumps meant for cooling or other such purposes. Electrohydrodynamics can be defined as a direct coupling between the electric and hydrodynamic fields, where the electric field produces fluid motion. The motion of the fluid can occur due to an electrical body force being exerted on the fluid. In single-phase liquid flows, the electrophoretic (Coulombic) component of the electrical body
