D ec 1 99 5 On Exactness Of The Supersymmetric WKB Approximation Scheme
Exactness of the lowest order supersymmetric WKB (SWKB) quantization condition x 2 x 1 E − ω 2 (x)dx = n¯ hπ, for certain potentials, is examined, using complex integration technique. Comparison of the above scheme with a similar , but exact quantization condition, c p(x, E)dx = 2πn¯ h, originating from the quantum Hamilton-Jacobi formalism reveals that, the locations and the residues of the po...
متن کاملSupersymmetric Electroweak Baryogenesis in the WKB Approximation
We calculate the baryon asymmetry generated at the electroweak phase transition in the minimal supersymmetric standard model, treating the particles in a WKB approximation in the bubble wall background. A set of diffusion equations for the particle species relevant to baryon generation, including source terms arising from the CP violation associated with the complex phase δ of the μ parameter, ...
متن کاملSemiclassical wave equation and exactness of the WKB method.
The exactness of the semiclassical method for three-dimensional problems in quantum mechanics is analyzed. The wave equation appropriate in the quasiclassical region is derived. It is shown that application of the standard leading-order WKB quantization condition to this equation reproduces exact energy eigenvalues for all solvable spherically symmetric potentials.
متن کاملMulti-Periodic Coherent States and the WKB-Exactness
We construct the path integral formula in terms of “multi-periodic” coherent state as an extension of the Nielsen-Rohrlich formula for spin. We make an exact calculation of the formula and show that, when a parameter corresponding to the magnitude of spin becomes large, the leading order term of the expansion coincides with the exact result. We also give an explicit correspondence between the t...
متن کاملLight scattering by cubical particle in the WKB approximation
In this work, we determined the analytical expressions of the form factor of a cubical particle in the WKB approximation. We adapted some variables (size parameter, refractive index, the scattering angle) and found the form factor in the approximation of Rayleigh-Gans-Debye (RGD), Anomalous Diffraction (AD), and determined the efficiency factor of the extinction. Finally, to illustrate our form...
