An entanglement-preserving photo-detector converts photon polarization to electron spin. Up and down spin must respond equally to oppositely polarized photons, creating a requirement for degenerate spin energies, ge ≈0 for electrons. We present a plot of ge-factor versus lattice constant, analogous to bandgap versus lattice constant, that can be used for g-factor engineering of III-V alloys and...

By combining a digital image with a lattice of points called atoms, in which atom coordinates are computed to minimize a potential energy function of the combination, we obtain a mesh suitable for further computations, such as flow simulation. Each atom in the lattice contributes a potential function to an atomic potential field. The image represents another potential field. Total potential ene...

Variation of lattice parameters depends on the surface energy and the size of nanoparticles. In the present work the model developed by W.H. Qi, and M.P. Wang to predict the size and shape dependence of lattice parameters of metallic nano-particles, has been reviewed in context to the different expressions of surface energy for the nanoparticles of Cu, Au and Pt. I have derived the expression o...

Lack of energy conservation in lattice Boltzmann models leads to unrealistically high values of the bulk viscosity. For this reason, the lattice Boltzmann method remains a computational tool rather than a model of a fluid. A novel lattice Boltzmann model with energy conservation is derived from Boltzmann's kinetic theory. Simulations demonstrate that the new lattice Boltzmann model is the valid...

The ratio of symmetry energy coefficient relative to the temperature, asym/T , has been extracted as a function of Z from the variance of the observed isotope distributions from the experiments described in Ref.[1]. In order to explore the relation between the symmetry energy term in the free energy and the variance of the isotope distribution, Ono et al. introduced a generalized function K(N,Z...

the synthesis of nanocrystalline fe3al powder by mechanical alloying as well as the structural ordering of the synthesized fe3al particles during the subsequent thermal analysis were investigated. mechanical alloying was performed up to 100 hours using a planetary ball mill apparatus with rotational speed of 300 rpm under argon atmosphere at ambient temperature. the synthesized powders were cha...

Three widely used scenaria for defining cuts on transverse energies of jets in ep collisions are discussed. All of them are shown to suffer from the same sort of unphysical behaviour when the cut regions are subject to additional constraints. This feature is inherent in the very way dijet cross sections are defined and cannot be avoided. In particular, the symmetric cut scenario is shown to be ...

With recent publicity outside the CMNS field it has become increasingly important to clarify in non-specialist terms what is known and what is understood in the general field of so called Low Energy or lattice Enhanced Nuclear Reactions (LENR). It is also crucial and timely to expose and elaborate what objections or reservations exist with regard to these new understandings. In essence we are c...

In the present paper the Ising model with competing binary J and J1 interactions with spin values ±1, on a Cayley tree is considered. We study translation-invatiant Gibbs measures and corresponding free energies ones.
