Bound energy for the exponential - cosine - screened Coulomb potential
where A is the strength coupling constant and δ is the screening parameter, is known to describe adequately the effective interaction in many-body enviroment of a variety of fields such as atomic, nuclear, solid-state, plasma physics and quantum field theory [1,2]. It is also used in describing the potential between an ionized impurity and an electron in a metal [3,4] or a semiconductor [5] and...
متن کاملA Cartesian treecode for screened coulomb interactions
A treecode algorithm is presented for evaluating electrostatic potentials in a charged particle system undergoing screened Coulomb interactions in 3D. The method uses a farfield Taylor expansion in Cartesian coordinates to compute particle–cluster interactions. The Taylor coefficients are evaluated using new recurrence relations which permit efficient computation of high order approximations. T...
متن کاملFerroelectric instability under screened Coulomb interactions.
We explore the effect of charge carrier doping on ferroelectricity using density functional calculations and phenomenological modeling. By considering a prototypical ferroelectric material, BaTiO(3), we demonstrate that ferroelectric displacements are sustained up to the critical concentration of 0.11 electron per unit cell volume. This result is consistent with experimental observations and re...
متن کامل0 Induced Variational Method from Supersymmetric Quantum Mechanics and the Screened Coulomb Potential 1
The formalism of Supersymmetric Quantum Mechanics supplies a trial wave function to be used in the Variational Method. The screened Coulomb potential is analysed within this approach. Numerical and exact results for energy eigenvalues are compared.
متن کامل2 00 6 Bound states of a more general exponential screened Coulomb potential
An alternative approximation scheme has been used in solving the Schrödinger equation to the more general case of exponential screened Coulomb potential, V (r) = −(a/r) [
