Comparative Study for Structure of Alkali Borate Glasses with and without Aluminum Oxide – Density Measurements
Abstract: This paper reports on density measurements of alkali aluminoborate glass system (xR2O − yAl2O3 − (1 − x − y)B2O3, R = Li, Na where x = 20 or 30 mol% and y = 10 or 15 mol%), correlated with the glass structure. The samples have been prepared by using the melt-quenching technique. The density has been obtained by Archimedes principle using benzene as buoyant. The effect of nature of …

Dependence of Fidelity of Quantum Teleportation for Pure State on Degree of Entanglement
Abstract: Quantum information and computation has been a rapidly evolving field. As Landauer pointed out, information is physical, so it should not look strange to try to bring together quantum mechanics and information theory. Indeed, it was soon realized that it was possible to use the laws of quantum physics to perform tasks which are unconceivable within the framework of classical physics like quantum teleportation, superdense coding, quantum cryptography, Shor’s factorization …

Determination of Magnetic Properties of Cobalt Films Using Second Order Perturbed Heisenberg Hamiltonian
Abstract: The magnetic properties of hexagonal closed packed structured ferromagnetic cobalt films were investigated by means of second order perturbed Heisenberg Hamiltonian. First the number of nearest neighbors and the constants arisen from the partial summation of the dipole interactions of the structure of cobalt were calculated using some special algorithms. Minimization of the energy difference between the easy and hard direction of a memory device is very important. When the …
