Amplification of Coupling for Yukawa Potentials
نویسندگان
چکیده
It is well known that Yukawa potentials permit bound states in the Schrödinger equation only if the ratio of exchanged mass to bound mass is below a critical multiple of the coupling constant. However arguments suggested by the Darwin term imply a more complex situation. By studying numerically the Dirac equation with a Yukawa potential we investigate this ”amplification” effect.

The massive Elko spinor field in the de Sitter braneworld model
The Elko spinor field is a spin 1/2 fermionic quantum field with a mass dimension introduced as a candidate of dark matter. In this work, we study the localization of Elko fields on a de Sitter thick brane constructed by a canonical or phantom scalar field. By presenting the mass-independent potentials of Kaluza-Klein (KK) modes in the corresponding Schrödinger equations, it is shown that the E...
متن کاملPresentation of the Soft-Core Double Yukawa Potential for Noble Gasses using in sillico
The understanding of the intermolecular pair potential is important for determining the physical andchemical properties of the matter. The new data for noble gasses was calculated with Soft-CoreDouble Yukawa Potential (SCDY). We studied the effect of the Soft- Core potential on the phasebehavior with Hartree-Fock-Dispersion (HFD) Potential. This model had a steep repulsionexponential term and d...
متن کاملGlass-transition properties of Yukawa potentials: from charged point particles to hard spheres.
The glass transition is investigated in three dimensions for single and double Yukawa potentials for the full range of control parameters. For vanishing screening parameter, the limit of the one-component plasma is obtained; for large screening parameters and high coupling strengths, the glass-transition properties cross over to the hard-sphere system. Between the two limits, the entire transit...
متن کاملLong Range Forces From Pseudoscalar Exchange
Using dispersion theoretic techniques, we consider coherent long range forces arising from double pseudoscalar exchange among fermions. We find that Yukawa type coupling leads to 1/r3 spin independent attractive potentials whereas derivative coupling renders 1/r5 spin independent repulsive potentials. Typeset using REVTEX 1
متن کاملA Hard Convex Core Yukawa Equation of State for Nonassociated Chain Molecules
The compressibility factor of nonassociated chain molecules composed of hard convex core Yukawa segments was derived with SAFT-VR and an extension of the Barker-Henderson perturbation theory for convex bodies. The temperature-dependent chain and dispersion compressibility factors were derived using the Yukawa potential. The effects of temperature, packing fraction, and segment number on the com...
