The complex optical conductivity tensor is calculated for the Co | Pt multilayer systems by applying a contour integration technique within the framework of the spin–polarized relativistic screened Korringa–Kohn– Rostoker method. It is shown that the optical conductivity of the Co |Pt multilayer systems is dominated by contributions arising from the Pt cap and/or substrate layers.

The form of the phenomenological stress-energy-momentum tensor for the electromagnetic field in a class of inhomogeneous, anisotropic magneto-electric media is calculated from first principles, leading to a coherent understanding of the phenomenological stresses and energy-momentum exchanges induced by electromagnetic interactions with such matter in terms of a fully relativistic covariant vari...

We consider the evolution equations for bulk viscous pressure, diffusion current and shear tensor derived within second-order relativistic dissipative hydrodynamics from kinetic theory. By matching higher order moments directly to quantities, all terms which are of second in Knudsen number Kn vanish, leaving only $\mathcal{O}(\textrm{Re}^{-1} \textrm{Kn})$ $\mathcal{O}(\textrm{Re}^{-2})$ relaxa...

We analyze the presence of an additional singular thin disk in the recent General Relativistic model of galactic gravitational field proposed by Cooperstock and Tieu. The physical variables of the disk’s energy-momentum tensor are calculated. We show that the disk is made of exotic matter, either cosmic strings or struts with negative energy density.

The relativistic Dirac equation under spin symmetry is investigated for generalized Morse potential. We calculated the eigenvalues and the corresponding wave function by using the Nikiforov-Uvarov method. We also discussed two special cases: attractive radial and Deng-Fan potentials. We have also reported some numerical results and figures to show the effect of tensor interaction.

An antisymmetric tensor, the photon tensor, is defined for the description of the photon as a massless relativistic particle. The classical photon can then be visualized as an essentially two dimensional rotating object. The quantummechanical description of a single photon is presented and the wave-particle duality for the photon is analysed. The intended relation between Schrödinger’s equation...

We generalize (linearized) relativistic hydrodynamics by including all order gradient expansion of the energy momentum tensor, parametrized by four momenta-dependend transport coefficients, one of which is the usual shear viscosity. We then apply the AdS/CFT duality for N = 4 SUSY in order to compute the retarded correlators of the energy-momentum tensor. From these correlators we determine a l...

Charmless hadronic decays of B mesons to a vector meson (V ) and a tensor meson (T ) are analyzed in the frameworks of both flavor SU(3) symmetry and generalized factorization. We also make comments on B decays to two tensor mesons in the final states. Certain ways to test validity of the generalized factorization are proposed, using B → V T decays. We calculate the branching ratios and CP asym...

We consider the dynamics of tensor and scalar gravitational fields in the Relativistic Theory of Gravitation with the Minkowskian vacuum metric and generalize the formulation to the massless graviton. The potential of scalar field is determined in the presence of cosmological term under clear physical motivations. We find cosmological inflationary solutions and analyze conditions providing the ...
