Decoupling of orbital and spin degrees of freedom in Li1-xNaxNiO2
In the Li1-xNaxNiO2 solid solutions three different single phase regions exist: for x > 0.9, forx = 0.7 and for

Geometric Conditions on the Type of Matter Determining the Flat Behavior of the Rotational Curves in Galaxies
In an arbitrary axisymmetric stationary spacetime, we determine the expression for the tangential velocity of test objects following a circular

Ghost Constraints on Modified Gravity
We show that general infrared modifications of the Einstein-Hilbert action obtained by addition of curvature invariants are not viable. These

Hydrodynamical description of Galactic Dark Matter
We consider simple hydrodynamical models of galactic dark matter in which the galactic halo is a self-gravitating and self-interacting gas

Infrared and visual lunar occultations measurements of stellar diameters and new binary stars detections at the Calar Alto 1.5m telescope
We present a program of routine lunar occultations, at optical and near-IR wavelengths, recently started at the 1.5m Spanish telescope

Interaction of D-branes on orbifolds and massless particle emission
We discuss various D-brane configurations in 4-dimensional orbifold compactifications of type II superstring theory which are point-like 0-branes from the

Stationary Axisymmetric Fields as Two-Dimensional Geodesics
Einstein's equations for stationary axisymmetric fields are reformulated as the equations for affine geodesics in a two--dimensional space. The affine
