Charge‐Current Output in Plasma‐Immersed Hydrogen Atom with Noncentral Interaction

Abstract

A theoretical investigation on the charge‐currents and induced magnetizations of hydrogen atoms with noncentral interaction, immersed in a plasma environment, under the influence of spherical encompassing is performed. The Hartmann potential for noncentral interaction is considered, but it is modified due to the plasma‐embedded hydrogen atom. The interactions in plasma are delineated by keeping in view the more general exponential cosine screened Coulomb (MGECSC) potential which reproduces more general and detailed outcomes. The shielding effect of the plasma environment is regarded by modifying the Hartmann potential through the MGECSC potential. Thus, the hydrogen atom is considered to be under the influence of the plasma modified Hartmann (PMH) potential. While the numerical tridiagonal matrix method (TMM) is employed due to the difficulty of analytical solution to the radial wave equation in nonrelativistic scheme including PMH potential, a hybrid solution technique is preferred by using asymptotic iteration method (AIM) to solve the angular wave equation. This study provides a detailed analysis of the plasma shielding, spherical confinement, and noncentral effect on the production and control of charge‐currents and induced magnetizations. In this analysis, the altenativeness to each other of the plasma environment, spherical encompassing, and noncentral effect is also evaluated, and suggestions are made for related application studies.

A Modified Inverse Iteration Method for Computing the Symmetric Tridiagonal Eigenvectors

“…Note that (8) computes p and q with no time cost savings per se. The two main contributors are: first, (7) reduces the cost of searching min |γ k |; second, (9) divides the eigenvector computation into two parts, and even under the most adverse condition of k = n/2, (9) can still reduce the multiplication operations by half compared to (5).…”

“…Computing the symmetric tridiagonal (ST) eigenvector is an important task in many research fields, such as the computational quantum physics [1], mathematics [2,3], dynamics [4], computational quantum chemistry [5], etc. The ST eigenvector problem also arises while solving any symmetric eigenproblem because it is a common practice to reduce the generalized symmetric eigenproblems to an ST one.…”

Control of Correlation Using Confinement in Case of Quantum System

“…It can be achieved by trapping the particles inside a box, applying external potentials, plasma, etc. [32][33][34][35][36][37][38][39][40][41][42] For example, the 1D harmonic oscillator limited by impenetrable walls is called a 1D confined harmonic oscillator (CHO). [43,44] As has been shown in many studies, quantum confinement changes the system's wave functions, energies, and other parameters, [45][46][47][48][49][50][51][52][53] which may result in a modified correlation.…”

The charge currents and induced magnetizations of hydrogen atoms with noncentral interaction, submerged in a plasma environment, are studied theoretically under the impact of spherical enveloping by Bahar 51 . The effects of plasma shielding, spherical confinement, and the non-central effect on the production and management of charge-currents and induced magnetizations are examined in depth in this work.…”
