The Feynman Representation for the Dirac Propagator with a Radially Symmetric Potential
نویسندگان
چکیده
The dynamical group associated with the Dirac equation with a radially symmetric potential in four space-time dimensions is represented in terms of integrals with respect to operator valued set functions associated with the free Dirac operator. In coordinates in which c = ~ = 1, the class of potentials treated includes Coulomb potentials ?a=r with jaj < 1.

Path Integral Representation for Weyl Particle Propagator
We present a path integral representation for massless spin one-half particles. It is shown that this gives us a super–symmetric, P − and T −non–invariant pseudoclassical model for relativistic massless spinning particles. Dirac quantization of this model is considered.
متن کاملNon-variational Computation of the Eigenstates of Dirac Operators with Radially Symmetric Potentials Lyonell Boulton and Nabile Boussaid
We discuss a novel strategy for computing the eigenvalues and eigenfunctions of the relativistic Dirac operator with a radially symmetric potential. The virtues of this strategy lie on the fact that it avoids completely the phenomenon of spectral pollution and it always provides two-side estimates for the eigenvalues with explicit error bounds on both eigenvalues and eigenfunctions. We also dis...
متن کاملExact Solution for Electrothermoelastic Behaviors of a Radially Polarized FGPM Rotating Disk
This article presents an exact solution for an axisymmetric functionally graded piezoelectric (FGP) rotating disk with constant thickness subjected to an electric field and thermal gradient. All mechanical, thermal and piezoelectric properties except for Poisson’s ratio are taken in the form of power functions in radial direction. After solving the heat transfer equation, first a symmetric dist...
متن کاملSpinor Parallel Propagator and Green’s Function in Maximally Symmetric Spaces
We introduce the spinor parallel propagator for maximally symmetric spaces in any dimension. Then, the Dirac spinor Green’s functions in the maximally symmetric spaces Rn, Sn and Hn are calculated in terms of intrinsic geometric objects. The results are covariant and coordinate-independent. ∗E-mail address: [email protected]
متن کاملMHD Flow of Blood through Radially Non-symmetric Stenosed Artery: a Hershcel-Bulkley Model (RESEARCH NOTE)
The purpose of this study is to develop a mathematical model for studying the magnetic field effect on blood flow through an axially non-symmetric but radially symmetric atherosclerotic artery. Herschel-Bulkley equation has been taken to represent the non-Newtonian character of blood. The response of magnetic field, stenosis height, shape parameter on velocity, volumetric flow rate in stenotic ...
