Explicit Multi-Symplectic Splitting Methods for the Nonlinear Dirac Equation - Volume 6 Issue 4
The Dirac equation Paul Dirac developed a theory that combined quantum mechanics, used to describe the subatomic world, with Einstein’s special relativity, which says nothing travels faster than
Although the Dirac equation cannot really be derived from anything learnt up to the present level, some plausibility Dirac Equation Consider the motion of an electron in the absence of electromagnetic fields. In classical relativity, electron energy, , is related to electron momentum, , according to the well-known formula The Dirac Equation. In a lifetime of scientific achievement, Dirac’s greatest accomplishment is, without a doubt, the Dirac equation. Erwin Schrödinger’s famous equation, describing the wave function of a quantum mechanical system, was itself an amazing discovery. However, it is limited in that it only encompasses the non-relativistic world.
It remains highly influential. It brought together two of the most important ideas in science: The Dirac equation is the starting point for relativistic quantum mechanics which evolved into the modern Quantum Field Theory. The purpose of this paper is to ticles is the Dirac equation, which we motivate as follows. (Throughout rect way to proceed is given by the relativistic equation relating energy and momentum,. Dirac's equation also contributed to explaining the origin of quantum spin as a relativistic phenomenon.
incorporate Special Relativity. It attempted to solve the problems with the Klein-Gordon Equation. In Quantum Field Theory, it is the field equation for the spin-1/2 fields, also known as Dirac Fields.

Lorentz group. In this section we will describe the Dirac equation, whose quantization gives rise to fermionic spin 1/2particles.TomotivatetheDiracequation,wewillstart by studying the appropriate representation of the Lorentz group. A familiar example of a field which transforms non-trivially under the Lorentz group is the vector field A Dirac Equation: Free Particle at Rest • Look for free particle solutions to the Dirac equation of form: where , which is a constant four-component spinor which must satisfy the Dirac equation • Consider the derivatives of the free particle solution substituting these into the Dirac equation gives: which can be written: (D10) • The Dirac Equation and The Lorentz Group Part I – Classical Approach 1 Derivation of the Dirac Equation The basic idea is to use the standard quantum mechanical substitutions p →−i~∇ and E→i~ ∂ ∂t (1) to write a wave equation that is first-order in both Eand p.

The quantum mechanical equivalent of this expression is the wave equation. The natural problem became clear: to generalize the Dirac equation to particles with any spin; both fermions and bosons, and in the same equations their antiparticles (possible because of the spinor formalism introduced by Dirac in his equation, and then-recent developments in spinor calculus by van der Waerden in 1929), and ideally with Dirac Equation.

In this section we are only interested in the Dirac equation, so we write the Lagrangian as: In Dirac’s notation what is known is put in a ket, . So, for example, expresses thep fact that a particle has momentum p. It could also be more explicit: , the particle hasp = 2 momentum equal to 2; , the particle has position 1.23. represents a system inx =1.23 Ψ the state Q and is therefore called the state vector.

In Quantum Field Theory, it is the field equation for the spin-1/2 fields, also known as Dirac Fields. 1 Statement 2 Relationship with Klein-Gordon Equation 3 In a Potential 4 Free Particle Solution 5 Relationship 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.
