We investigate the physical properties of a purely kinetic k-essence model with an equation of state motivated in superconducting membranes. We compute the equation of state parameter $w$ and discuss its physical evolution via a nonlinear equation of

We construct ladder operators for spherical Bessel functions of arbitrary order. Our ladder operators act independently on two parameters, one of which is the order of the spherical Bessel function, while the other parameter is a multiplicative facto

We show that the supersymmetric radial ladder operators of the three-dimensional isotropic harmonic oscillator are contained in the spherical components of the creation and annihilation operators of the system. Also, we show that the constants of mot

For the quantum two-dimensional isotropic harmonic oscillator we show that the Infeld–Hull radial operators, as well as those of the supersymmetric approach for the radial equation, are contained in the constants of motion of the problem.

The equations of motion for a relativistic extended object loaded with a superconducting edge are found in terms of geometrical quantities defined on the worldsheet. The results are applied to the study of a domain wall bounded by a superconducting s

We study the production process\(pp(p\bar p) \to W^ \pm Z^0 X\), where\(p(\bar p)\) is a proton (antiproton), allowing an anomalous weak magnetic dipole moment parameter κZ in the ZWW vertex. We compute the pairWZ mass invariant, and total cross sec

We study the logarithmic pion-mass singularities in the radiative corrections, to order {alpha}, to the decay {tau}{r arrow}{pi}{nu}{sub {tau}}. We show that such contributions are independent of strong-interaction effects. We verify that the total d
