Abstract

One-dimensional stationary state problem is discussed in this paper.Based on this discussion, wave function can be figured from potential field whereas potential field can be figured from wave function.

Stationary motion of a quantum particle in the field of a one-dimensional arbitrary potential

А. Ж. Хачатрян, Д. М. Седракян, V. A. Khoetsyan

A new approach to the problem of description of the stationary motion of a quantum particle in the field of a one-dimensional arbitrary potential is developed. It is shown that the wave function of infinite motion, with the accuracy to two arbitrary constants, can be expressed by means of an arbitrary single solution for some set of linear differential equations of the first order. It is shown that one general property of the Schrödinger equation solutions lies in the basis of many known methods of the problem consideration, such as the method of integral equations, transfer-matrix method, imbedding method, and method of combination of scattering parameters. Within the framework of the proposed approach, the connection between the above-mentioned methods becomes more transparent.

Stationary states in a potential well

Haret Codratian Rosu, José Luis Morán-López

We review here in a historical context the topic of stationary states in the quantum world, including the generalization to the primary ideas. We also discuss the stationary states in one dimensional parabolic wells and the three dimensional Coulomb and parabolic cases, as well as the stationary bound states in the continuum

Using the graphic method to study two-dimensional square potential well

Peng Yun-xiong

In this paper, the energy levels, wave function and probability density of a particle moving in a two-dimensional square potential well have been studied with the stationary state Schr[AK]dinger equation. The wave form of wave function and probability density are drawn and presented with TC or MATLAB. Some special examples concerning about wave form of wave function have been also discussed.

The Derivation of the Medium Wave Function in a One-Dimensional Finite Deep Symmetrical Square Potential Well

Zhao Peng-y

Three methods-a documental analysis, a textual method, a comprehensive analysis- are used in this article to analyze the energy levels of motional particles and their wave functions of one-dimensional finite deep symmetrical square potential wells, thus solving the eigen-values and eigen-functions at their corresponding energetic levels. Due to the three following advantages of a one-dimensional problem-its simpler mathematical processing, and the possible detailed-discussed results, and the display of the many features of quantum systems, so in the paper, the eigen-values and the exact formulas of the wave functions of moving particles in a one-dimensional finite deep symmetric square potential wells, which are not specified in the textbooks, are deviated according to the Schrodinger equation of stationary state through a case study of moving particles in a one-dimensional finite deep symmetric square potential wells.
