optic properties of uranium-based compounds" Uranium-based compounds often show interesting magnetic properties and large polar Kerr rotations. Because of this, the wavelength and temperature dependencies of the polar Kerr rotation in several uranium-based compounds, including UMnzGez, UFe2, and UGa2, have been investigated. The Mn moments order ferromagnetically in UMnzGel below 380 K, and whi...

We report an experimental study on magneto-optical (MO) Kerr effects of yttrium-iron garnet (YIG) thin films incorporating Au nanoparticles. The polar MO Kerr spectra in the wavelength between 400 and 800 nm show that, by incorporating the Au nanoparticles, Kerr rotation angles become negative values in the region, where the localized surface plasmon polariton (SPP) resonance of the Au nanopart...

Using the counterterm subtraction technique we calculate the stress–energy tensor, action, and other physical quantities for Kerr–AdS black holes in various dimensions. For Kerr–AdS5 with both rotation parameters non–zero, we demonstrate that stress–energy tensor, in the zero mass parameter limit, is equal to the stress tensor of the weakly coupled four dimensional dual field theory. As a resul...

The Cardy-Verlinde formula, which expresses the entropy of the conformal field theory in terms of its total energy (or the extensive energy), Casimir energy and radius of the unit sphere S, is further verified by using the Kerr-Newman-AdS4 and the two rotation parameters Kerr-AdS5 black holes. For the Kerr-Newman-AdS4 black hole we find that to cast the entropy of the conformal field theory int...

Monolayer transition-metal dichalcogenides have recently emerged as possible candidates for valleytronic applications, as the spin and valley pseudospin are directly coupled and stabilized by a large spin splitting. The optical properties of these two-dimensional crystals are dominated by tightly bound electron-hole pairs (excitons) and more complex quasiparticles such as charged excitons (trio...

In this note we prove that the Hamilton-Jacobi equation in the background of the recently discovered charged Kerr-AdS black hole of D = 5 minimal gauged supergravity is separable, for arbitrary values of the two rotation parameters. This allows us to write down an irreducible Killing tensor for the spacetime. As a result we also show that the Klein-Gordon equation in this background is separabl...

The standard scalar paraxial parabolic (Fock–Leontovich) propagation equation is generalized to include allorder nonparaxial corrections in the significant case of a tensorial refractive-index perturbation on a homogeneous isotropic background. In the resultant equation, each higher-order nonparaxial term (associated with diffraction in homogeneous space and scaling as the ratio between beam wa...

The inclination of low-eccentricity orbits is shown to significantly affect the orbital parameters, in particular, the Keplerian, nodal precession, and periastron rotation frequencies, which are interpreted in terms of observable quantities. For the nodal precession and periastron rotation frequencies of low-eccentricity orbits in a Kerr field, we derive a Taylor expansion in terms of the Kerr ...
