Abstract

We study theoretically the level shift of the Dirac oscillator perturbed by any sharply peaked potential approaching a surface delta potential. A Green function method is used to obtain closed expressions for all partial waves and parities.

Spectroscopy of a Perturbed Dirac Oscillator

Francisco Domínguez-Adame

Energy levels of the Dirac oscillator perturbed by arbitrary nonlocal separable vector and scalar potentials are found in a closed form. Unlike the nonrelativistic case, the perturbation potential radically changes all energy levels of the oscillator. The δ-function limit of the perturbation potential is discussed in detail.

An exact treatment of the Dirac delta function potential in the Schrödinger equation

Daniel A. Atkinson, Horace W. Crater

This paper presents several cases in which the effects of the addition of a delta function potential on bound states can be computed exactly. In the case of the one dimensional Schrödinger equation, a Green’s function technique is used to compute an exact implicit expression that gives the effect of the one−dimensional delta function potential on the bound states eigenvalues. It is also shown that the weak coupling limit of the implicit expression agrees with the perturbative treatment of the delta function. It is pointed out that this technique cannot be applied to obtain an exact treatment of the delta function potential δ3(r) in the three−dimensional Schrödinger equation. Instead, an alternate definition of the delta function in three dimensions as a limit of a sequence of square well potentials is used. Unlike the one dimensional case, the exact effect on the eigenvalue does not agree in the limit of weak coupling with the perturbative results. This indicates that the three−dimensional delta function potential should not be used to approximate strongly coupled short range potentials for which perturbation theory is inadequate.

Exact solutions of the Dirac equation with surface delta interactions

Francisco Domínguez-Adame

The Dirac equation with vector plus scalar surface delta interactions supported by a sphere is exactly solved for all partial waves and parities. Unlike the relativistic one-dimensional delta potentials, surface delta interactions with finite values of the vector and scalar coupling constants require a minimum strength to bind particles. Strong scalar couplings confine relativistic particles at high energies inside the sphere, while the confinement is no longer possible for strong vector potentials. It is also found that the potential causes no effects on the scattering phase shift in the zero-range limit. Therefore, the well known Dirac-Kronig-Penney model in one dimension cannot be generalised to three-dimensional crystal lattices.

Perturbation of δ Potential on the Energy Level of a Onedimensional Quantum Well

Kaiyi Li

The paper studied the effect of a suddenly intruded δ potential on the energy level of a one-dimensional quantum well by perturbation method.It is found that δ potential has no effect on the odd parity states of the system but it makes the energy level of the even parity states have a constant shift,and the degree of the shift depends on the intensity of δ potential.
