In the context of the Hamiltonian formulation of the teleparallel equivalent of general relativity we compute the gravitational energy of Kerr and Kerr Anti-de Sitter (Kerr-AdS) space-times. The present calculation is carried out by means of an expression for the energy of the gravitational field that naturally arises from the integral form of the constraint equations of the formalism. In each ...

In the work, there have been investigated the optical power limiting effects which occur in the nonlinear photonic crystals possessing saturable Kerr nonlinearity. The method is proposed which allows exact determination of the parameters of the structure as well as the radiation parameters which provide the limiting effect.

We generalize a construction of the Néron model for a family of intermediate Jacobians due to Green, Griffiths and Kerr by using the theory of mixed Hodge modules. It is a topological group defined over any partial compactification of the base space, and it ‘graphs’ admissible normal functions. Moreover, there is a stratification of the partial compactification such that the restriction over ea...

We consider a model in which accelerated particles experience line–elements with maximal acceleration corrections that are introduced by means of successive approximations. It is shown that approximations higher than the first need not be considered. The method is then applied to the Kerr metric. The effective field experienced by accelerated test particles contains corrections that vanish in t...

Electric-field-induced birefringence of a polymer-stabilized blue-phase liquid crystal BPLC is investigated. In the low field region, conventional Kerr effect holds. As the electric field increases, the induced birefringence gradually saturates and deviates from Kerr effect. An exponential convergence model, called extended Kerr effect, is proposed to fit the experimental data. Good agreement b...

We propose to create an effective magnetic field for photons in photonic crystal resonator lattices using the magneto-optical effect. The inter-resonator coupling is mediated by magneto-optical waveguides or magnetooptical resonators, and thus the coupling between the nearest-neighbor photonic crystal resonators acquire a direction-dependent phase. The effective magnetic field can be realized w...

In the context of the natural splitting, the standard relative dynamics can be expressed in terms of gravito-electromagnetic fields, which allow to formally introduce a gravito-magnetic Aharonov-Bohm effect. We showed elsewhere that this formal analogy can be used to derive the Sagnac effect in flat space-time as a gravito-magnetic AharonovBohm effect. Here, we generalize those results to study...

We have carried out a detailed study of the magnetic switching in square lattice cobalt antidot arrays with periods ranging from 2 m down to 200 nm antidot size=antidot separation . Magneto-optical Kerr effect measurements show first a small change in the magnetization due to a reversible rotation of the magnetic spins in the antidot rows, followed by a large change due to reversal of the antid...
