摘要:Abstract(#br)In this paper, we are concerned with an inverse problem for the Sturm-Liouville operator with Coulomb potential using a new kind of spectral data that is known as nodal points. We give a reconstruction of q as a limit of a sequence of functions whose n th term is dep...

摘要:Abstract(#br)The frequently-used Z k and Y k functions in the framework of numerical Hartree–Fock method are formulated for atomic systems embedded in weakly-coupled plasmas modeled by Debye–Hückel potential. The Gegenbauer expansion is used to decompose the screened inte...

摘要:Abstract(#br)The Coulomb potential between two heavy ions at their interpretation condition has been represented in terms of two point charges with reduced effective charge, dependent on overlap volume. This representation enables visualization of the dynamic development of the d...

摘要:Abstract(#br)Analytical expressions for the planar density of an induced vacuum charge are obtained in a strong Coulomb potential in coordinate space. Treatment is based on a self-adjoint extension approach for constructing of the Green's function of a charged fermion in an exter...

摘要:Abstract(#br)We present a novel numerical method and algorithm for the solution of the 3D axially symmetric time-dependent Schrödinger equation in cylindrical coordinates, involving singular Coulomb potential terms besides a smooth time-dependent potential. We use fourth orde...

摘要:Abstract(#br)The Gegenbauer expansion and Taylor expansion methods are developed to accurately and efficiently calculate the two-electron screened Coulomb potential integrals in Hylleraas basis sets. The combination of these two methods covers the entire parameter space of the in...

摘要:Abstract(#br)The approximate analytical solutions of the D-dimensional space of the Schrӧdinger equation is studied with a newly proposed potential model. The proposed potential is a combination of Coulomb potential and inverse trigonometry scarf-type potential. The energy eq...

摘要:Abstract(#br)Exact solutions of the potential V(r) =− Ze 2 /( r + β ), β >0 are obtained in the N -dimensional space for certain values of β by means of factorization of infinite Hill determinant. We discuss some features of the radial wave Schrödinger equation in the N...

摘要:Abstract(#br)Solutions of Schrödinger's equation are presented for two-particle system interacting through generalized exponential cosine screened Coulomb potential. Solutions are computed for several values of screening parameters. In the present context, Ritz variation me...
