The aim of this study is to show that geometric phase is a consequence of curvature in non-Euclidean geometries being related to the areas of spherical and hyperbolic triangles. In hyperbolic geometry it is well-known that the angular deficit of a hyperbolic triangle is related t...

I consider the teleportation of superposition of coherent states and using beam splitters and phase shifters. I propose some modifications which consist of writing the output state as a superposition of the vacuum state and nonzero even photon state, which allow for an almost p...

We investigate the motion of an electron in a one dimensional crystal coupled to an EMF potential, driven by an external force which is continuously switched on and off. The Shannon entropy and the thermodynamic parameters of the system are evaluated using the density matrix and...
A Theoretical approach for studying the structure of copper (II) amino acid complexes have been carried out using extended X-ray absorption fine structure (EXAFS). The fine structure of the complexes was done for six copper (II) amino complexes. The theoretical bond lengths of th...
