TL;DR: In this paper, the boundary conditions for the scalar potential and each of the components of the vector potential were determined for a two-dimensional eddy current problem with variable electric conductivity.
Abstract: In calculating eddy currents in a conductor by means of the vector potential for which the Coulomb Gauge is used, the scalar potential appears when the electric conductivity varies in the conductor, while it is not necessary for the case of the constant electric conductivity. As the field equation is a Helmholtz-type equation under the Coulomb Gauge condition, we must determine the boundary conditions for the scalar potential and each of the components of the vector potential. How to determine the boundary conditions is presented, together with an illustrative example of a two-dimensional eddy current problem with the variable electric conductivity.

TL;DR: In this paper, the relativistic transport model is extended to include the kaon degree of freedom, and the propagation of kaons in the mean-field potential and the kon-baryon elastic scattering are explicitly treated.
Abstract: The relativistic transport model, in which the nucleon effective mass is connected to the scalar field while its energy is shifted by the vector potential, is extended to include the kaon degree of freedom. We further take into account the medium modification of the kaon mass due to the explicit chiral symmetry breaking. Both the propagation of kaons in the mean-field potential and the kaon-baryon elastic scattering are explicitly treated in our study. We find that the attractive kaon scalar mean-field potential in the dense matter leads to an enhanced kaon yield in heavy-ion collisions at energies of about 1 GeV/nucleon. The final-state kaon-baryon scattering is seen to affect significantly the kaon momentum spectra, leading to an enhanced yield of kaons with large momenta or at large laboratory angles. With a soft nuclear equation of state and including the attractive kaon scalar potential, the calculated kaon energy spectra agree with the data from the heavy-ion synchrotron at GSI.

TL;DR: In this paper, the Klein-Gordon (KG) equation for the linear combination of Hulthen and Yukawa potentials is solved based on a developed scheme, and the eigenvalues and corresponding radial wave functions expressed by the Jacobi polynomials or hypergeometric functions are consistent.

TL;DR: In this paper, a fixed-grid methodology for the numerical simulation of electromagnetic driven flow in three-dimensional inductively stirred systems is described, which is based on a hybrid differential-integral formulation of the electromagnetic field to limit the finite difference/element solution of the problem to the fluid flow domain.
