In this paper, following a stream of investigation of supersymetric gauge theories with cosmic string solutions, we contemplate the possibility of building up a superconducting cosmic string with a gauge-field mixing in conection with to a U(1) × U(1)′symmetry. Both spontaneous breakings, of gauge and supersymmetry, are thoroughly analysed and the fermion zero-modes are worked out. The rôle of ...

A 2D, hexagonal in geometry, statistical model of fracture is proposed. The model is based on the drying fracture process of the bamboo Guadua angustifolia. A network of flexible cells are joined by brittle junctures of fixed Young moduli that break at a certain thresholds in tensile force. The system is solved by means of the Finite Element Method (FEM). The distribution of avalanche breakings...

We present the Hartree-Fock approximation method for the many-body problems in Quantum Mechanics cor r esponding to the interaction of neutrons and protons We study the vanous farms of Hartree-Fock équations, the questions related to spin-dependence and spin-orbtt forces, symmetries of the nucleus and symmetry breakings and time-dependent Hartree-Fock équations AMS (MOS) Subject Classifications...

We derive formula of soft supersymmetry breaking scalar masses from 4-dimensional string models within a more generic framework. We consider effects of extra gauge symmetry breakings including an anomalous U(1) breaking through flat directions, that is, D-term and F -term contributions, particle mixing effects and heavy-light mass mixing effects. Some phenomenological implications are discussed...

We study the dependence of viscosity of ethanol on shear rate using constant volume and constant pressure nonequilibrium molecular dynamics simulations, with the emphasis of the interrelationship between breaking, stability, and alignment of hydrogen bonds and shear thinning at high shear rates. We find that although the majority of hydrogen bond breakings occur at low shear rates, we do not ob...

Different ways exist in optics to realize photons carrying non-zero orbital angular momentum. Such photons with rotating wave fronts are called twisted photons. In microwaves, twisted fields can be produced based on small ferrite particles with magnetic-dipolar-mode (MDM) oscillations. Recent studies showed strong localization of the electric and magnetic energies of microwave fields by MDM fer...
