In this paper a new approach to obtain the interface propagation speed in superconductors by means of a variationalme thod is introduced. The results of the approach proposed coincide with the numerical simulations. The hyperbolic differential equations are introduced as an extension of the modelin order to take into account delay effects in the front propagation due to the pinning.
We study the interface propagation in superconductors by means of a variational method. We compute the lower and upper bounds for which the planar front speed propagation is valid. To take into account delay or memory effects in the front propagation, an hyperbolic differential equation is introduced as an extension of the model.
The contribution of the charged right-handed higgsino fields to the chargino mass spectrum in the context of the Left-Right Supersymmetric Model is studied. Analytical expressions for the chargino masses assuming arbitrary CP-violating phases are given. Also, the corresponding inverse parameter problem is studied. Analytical disentangling of some relevant parameters is presented. A general inversion algorithm, based on suitable measurement of cross-section type observables associated to chargino pair production in electron positron annihilation, is proposed.
The magnetic force microscopy inverse problem for the case of horizontal scanning of a tip on a linear magnetic film is introduced. We show the possibility to recover the magnetic permeability of the material from the experimental data by using the Hankel (Fourier-Bessel) transform inverse method (HIM). This method is applied to the case of a layered slab film as well. The inverse problem related to the ac MFM is introduced.
We report exact analytical expressions relating the fundamental parameters describing the neutralino sector in the context of the left-right supersymmetric model. The method used for such a effects is the projector formalism deduced without take into account the Jarlskog's projector formulae. Also, expressions for the neutralino masses and the neutralino mixing matrix are determined . The results are compared with numerical and analytical ones obtained in similar scenarios in the context of the minimal supersymmetric standard model.
