# Eigen value equation dirac particles and dirac oscillators

Seeing 5 times more particles scattered than what you have put in), this 3 dirac equation 31 heuristic derivation dirac was the ﬁrst to realize the problem with the probability interpretation because the energy eis the eigenvalue of the hamitonian, we act hagain on the dirac wave function and ﬁnd. 1 elements of dirac notation frank rioux in the early days of quantum theory, p a m (paul adrian maurice) dirac created a powerful and concise formalism for it which is now referred to as dirac notation or bra-ket. Spin and pseudospin symmetries of dirac equation are solved under scalar and vector generalized isotonic oscillators and cornell potential as a tensor interaction for arbitrary quantum number via the analytical ansatz approach the spectrum of the system is numerically reported for typical values of the potential parameters. Amusingly, a search on these three words here in pf does not show a lot of postings, so i am creating this thread so you can ask all your doubts about n-dimensional majorana, weyl and dirac particles, their representations, their lagragians, masses, and whatever you have always wanted to know :tongue.

Dirac equation for spin ½ particles 2 quantum-electrodynamics and feynman rules 3 fermion-fermion scattering 4 higher orders dirac equation: where and , i 1,2,3 1 0 1 0 0 2 are eigenstates of with eigenvalues. The dirac equation is one of the two factors, and is conventionally taken to be p m= 0 (31) making the standard substitution, p [email protected] we then have the usual covariant form of the dirac equation (i @ recall that each component of the spin operator s for spin 1/2 particles is. Overcome and the kg equation is used to describe spin-0 particles (inherently single particle description multi-particle quantum excitations of a scalar field) nevertheless: •this is the dirac equation in “momentum”–note it contains no derivatives. The dirac-pauli equation for neutral dirac particles we consider the motion of a neutral fermion of spin-1/2 with mass mand an anomalous magnetic moment µ, in an external electromagnetic ﬁeld described by the ﬁeld strength.

The dirac equation predicts that the electron magnetic moment and its spin are related as µ=2 µbs, while for normal orbital motion µ=µ b l detailed calculations give small corrections to the factor g=2 and its precise. Dirac showed that there is no relativistic version of the pauli-schroedinger equation that has two components and that the minimal relativistic analogue is a four component equation[1] the additional other components (or degrees of freedom) in the dirac equation are the antiparticles as states. So if we want a description of spin-1/2 particles which respects parity, the possible eigenvalues of j3 are (+1,0,−1) and 0, corresponding to the eigen-value of j2 being j(j+1) with j= 1 or 0 symbolically, we write 20 version of february 4, 2005 chapter 1 dirac equation. Act with b on the eigenvalue equation of a: on one side you should have baf while on the other side you use again the expansion of bf now, subtract the two relations: one side should be zero because of the commutation relation. Since the two-body equation, eq218, describes two dirac particles, each being rep- resented by dirae spinors in the space of particle 1 and 2 and their wave function will be a sixteen component matrix as mentioned earlier.

An exact solution of the dirac oscillator problem in the context of generalized uncertainty principle the solution method presented here depends on the knowledge of the energy eigenvalues of the quantum (52) are the equation of harmonic oscillators with frequency ω hence, we find from equation (51) and (52) for the spectrum of 1. In this paper we studied the eigen value equation for dirac particles and dirac oscillators, considering the spin and generalized uncertainty principle then we calculated the thermodynamic entities for them with the generalized uncertainty principle corrected we find that an electron of mass m and. The dirac equation is solved by reducing the dirac equation to the form of schrodinger equation the nikiforov-uvarov method is app ied to obtain the energy eigenvalues and corresponding wave functions. Notes on the dirac delta and green functions andy royston november 23, 2008 1 the dirac delta one can not really discuss what a green function is until one discusses the dirac delta \function.

## Eigen value equation dirac particles and dirac oscillators

The two-body dirac oscillator and kemmer oscillators m bednar, j ndimubandi, and ag nikitin equations for interacting particles the aim of such a question at the first quantized level is to look for tivistic oscillators [9] (ii) the eigenvalue problems for the pararelativistic oscillator and dkp oscillator. Eigenvalue equations hermitian conjugate of an operator hermitian operators extending qm to two particles and three dimensions quantum mechanics for two particles solution of dirac equation for a free particle ``negative energy'' solutions: hole theory. And whose eigenvalues could give a clue to the mass spec- trum of the elementary particles both of the dirac oscillators [5(a) and 5(b)] are implemented by means of the vector coupling tor coupling in the dirac equation, see chap 3 of greiner, miiller, and rafelski‘ ) instead of modifying the momentum as in (6), one modifies the.

• To have an eigenvalue of +1, a spinor must have zero second and fourth components and to have an eigenvalue of -1, the first and third components must be zero so boosting our dirac particle to a frame in which it is moving, mixes up the spin states.
• The dirac oscillator coupling is introduced via the following replacement in dirac equation: p → p − im ω β x, where m is a mass of the particle, and ω is the frequency of the oscillator.
• Equation with the dirac relativistic oscillator in ordinary commutative space [12–18] as we know, in the domain of relativistic extension ncqm, dirac oscillator and klein gordon oscillator has been discussed by mirza et al in noncommutative space [19], and so.

Dirac's free particle equation originated in an attempt to express linearly the relativistic quadratic relation between energy and momentum the authors introduce a dirac equation which, besides the momentum, is also linear in the coordinates. In physics, the dirac equation is a relativistic quantum mechanical wave equation formulated by british physicist paul dirac in 1928 and provides a description of elementary spin-½ particles, such as electrons, consistent with both the principles of quantum mechanics and the theory of special relativity. The dirac oscillator in a noncommutative space has a similar equation to the equation of motion for a relativistic fermion in a commutative space and in a magnetic ﬁeld, however a new exotic term appears, which implies that a charged fermion in a noncommutative space has an electric dipole moment. We study (1+1)-dimensional dirac equation with non-hermitian interactions, but real energies in particular, we analyze the pseudoscalar and scalar interactions in detail, illustrating our observations with some examples we also show that the relevant hidden symmetry of the dirac equation with such an interaction is pseudo-supersymmetry.
