Dirac's equation for the electron in Kerr geometry is separated; and the general solution is expressed as a superposition of solutions derived from a purely radial
2019-12-01 · We construct general solutions of the time-dependent Dirac equation in (1+1) dimensions with a Lorentz scalar potential, subject to the so-called Majorana condition, in the Majorana representation. In this situation, these solutions are real-valued and describe a one-dimensional Majorana single particle.

The deformed Dirac equation invariant under the -Poincaré-Hopf quantum algebra in the context of minimal and scalar couplings under spin and pseudospin symmetry limits is considered. The -deformed Pauli-Dirac Hamiltonian allows us to study effects of quantum deformation in a class of physical systems, such as a Zeeman-like effect, Aharonov-Bohm effect, and an anomalous-like Solution of Dirac Equation for a Free Particle As with the Schrödinger equation, the simplest solutions of the Dirac equation are those for a free particle. They are also quite important to understand.

10 Sep 2020 2.7: Solution of the Dirac equation for a free particle. Last updated In particular, we look for free-particle (plane-wave) solutions of the form:.
Dirac’s equation is a relativistic wave equation which explained that for all half-spin electrons and quarks are parity inversion (sign inversion of spatial coordinates) is symmetrical. The equation was first explained in the year 1928 by P. A. M. Dirac. The equation is used to predict the existence of antiparticles. In this video, we will show you how to solve the Dirac equation for moving particles in any reference frame.
The general solution of the free Dirac equation is not just one plane wave with a well-defined momentum, since that is not the most general state of a single particule. The general solution is actually a superposition of waves with all possible momenta (and spins*).

They are also quite important to understand. We will find that each component of the Dirac spinor represents a state of a free particle at rest that we can interpret fairly easily. Mathematical formulation. The Dirac equation in the form originally proposed by Dirac is: ( β m c 2 + c ∑ n = 1 3 α n p n ) ψ ( x , t ) = i ℏ ∂ ψ ( x , t ) ∂ t {\displaystyle \left (\beta mc^ {2}+c\sum _ {n\mathop {=} 1}^ {3}\alpha _ {n}p_ {n}\right)\psi (x,t)=i\hbar {\frac {\partial \psi (x,t)} {\partial t}}}
which is called a four-component Dirac spinor. In order to generate an eigenvalue problem, we look for a solution of the form which, when substituted into the Dirac equation gives the eigenvalue equation Note that, since is only a function of, then so that the eigenvalues of can be used to characterize the states.

The Dirac Equation. This is the time Paul Dirac comes into the picture. Dirac worked on solving these two problems and combining special relativity and quantum mechanics. With rigorous mathematical efforts, he derived an equation that did solve the problem of the negative probability density but still had negative energy solutions in it.
