The trial wave function of the fractional quantum Hall effect (FQHE) on a disk at filling ν = 1/m with m an old integer is given by the famous Laughlin wave function [1]. Laughlin wave function had been constructed on a spheric or a toric surface later in refs. [2, 3]. When ν 6= 1/m, there are several proposals for constructing the trial wave function, notably Halperin’s hierarchical wave funct...

fresnel zone plate antenna (fzpa) was considered as a recieving antenna. an expression of electric field on axis of antenna produced by an incidente plane wave was found . the expression was used for calculation of gain, efficiency and optimum phase correcting function. several fzpa are fabricated and tested. experimental and theoretical results were compared and it was shown that there was a g...

Zufiria’s higher-order Boussinesq type equations are studied by transforming them into solvable ordinary differential equations. Various families of their travelling wave solutions are generated, which include periodic wave, solitary wave, periodic-like wave, solitonlike wave, Jacobi elliptic function periodic wave, combined non-degenerative Jacobi elliptic function-like wave, Weierstrass ellip...

Calculation of the scattering phase shift is important to understand scatterings and decays of hadrons. The phase shift in I = 2 ππ scattering system [3] was evaluated with the finite volume method [1,2] derived by Lüscher. In the finite volume method two-particle wave function plays an important role, because the phase shift is extracted by the wave function. Study of the wave function was car...
