Abstract

For one dimensional motions, we derive from the Dirac Spinors Equation (DSE) the Quantum Stationary Hamilton-Jacobi Equation for particles with spin 1/2. Then, We give its solution. We demonstrate that the $QSHJES_{1\over2}$ have two explicit forms, which represent the two possible projection of the Spin 1/2.

The quantum Hamilton–Jacobi equations for the Dirac and the Dirac–Klein–Gordon systems

T. Djama

For one dimensional systems, we derive from the Dirac spinor equation (DSE) the relativistic quantum stationary Hamilton–Jacobi equation (RQSHJES) for particles of spin . We establish that the RQSHJES ±1/2 is constituted of two equations, each one corresponding to the positive and negative energies (particle and antiparticle). The solution of the RQSHJES ±1/2 is well established. We also investigate the Dirac–Klein–Gordon equation and set its corresponding Hamilton–Jacobi equation.

The Relativistic Quantum Motions.

Using the relativistic quantum stationary Hamilton-Jacobi equation within the framework of the equivalence postulate, and grounding oneself on both relativistic and quantum Lagrangians, we construct a Lagrangian of a relativistic quantum system in one dimension and derive a third order equation of motion representing a first integral of the relativistic quantum Newton’s law. Then, we plot the relativistic quantum trajectories of a particle moving under the constant and the linear potentials. We establish the existence of nodes and link them to the de Broglie’s wavelength. PACS: 03.65.Bz; 03.65.Ca; Key words: relativistic quantum law of motion, Lagrangian, relativistic quantum stationary Hamilton-Jacobi equation, relativistic velocities.

In this paper, we give the solution of the three dimensional quantum stationary Hamilton-Jacobi Equation (3D-QSHJE) for a general form of the potential. We present the quantum coordinates transformation with which the 3D-QSHJE takes its classical form. Then, we derived the 3D quantum law of motion.

Quantum Stationary Hamilton Jacobi Equation in 3-D for symmetrical potentials. Introduction of the Spin

T. Djama

We establish the quantum stationary Hamilton-Jacobi equation in 3-D and its solutions for three symmetrical potentials, Cartesian symmetry potential, spherical symmetry potential and cylindrical symmetry potential. For the two last potentials, a new interpretation of the Spin is proposed within the framework of trajectory representation.

The 3D quantum law of motion and the 3D quantum trajectories

T. Djama

In this paper, we resolve the three-dimensional quantum stationary Hamilton–Jacobi equation (3D-QSHJE) for a general form of the potential, and discuss the nature of the hidden antisymmetric tensor introduced by Bertoldi et al. We derive the 3D quantum law of motion and plot the 3D quantum trajectories of a free particle (electron).
