Approximate Solution of the effective mass Klein-Gordon Equation for the Hulthen Potential with any Angular Momentum
The radial part of the effective mass Klein-Gordon equation for the Hulthen
potential is solved by making an approximation to the centrifugal potential.
The Nikiforov-Uvarov method is used in the calculations. Energy spectra and the
corresponding eigenfunctions are computed. Results are also given for the case
of constant mass.Comment: 12 page
Magnetic flux inversion in Charged BPS vortices in a Lorentz-violating Maxwell-Higgs framework
We demonstrate for the first the existence of electrically charged BPS
vortices in a Maxwell-Higgs model supplemented with a parity-odd
Lorentz-violating (LV) structure belonging to the CPT-even gauge sector of the
standard model extension and a fourth order potential (in the absence of the
Chern-Simons term). The modified first order BPS equations provide charged
vortex configurations endowed with some interesting features: localized and
controllable spatial thickness, integer flux quantization, electric field
inversion and localized magnetic flux reversion. This model could possibly be
applied on condensed matter systems which support charged vortices carrying
integer quantized magnetic flux, endowed with localized flipping of the
magnetic flux.Comment: 6 Latex 2e pages, 5 figures. To appear in Physics Letters
