Comment on `Dimensional expansion for the delta-function potential'

Abstract

I criticize the claim, made in a recent article (Bender C M and Mead L R 1999 Eur. J. Phys . 20 117-21) that, in order to obtain the correct cross section for the scattering from a two-dimensional delta-function potential, one must perform analytic continuation in the dimension of space.

Repulsive Delta-Function Potential in Two and Three Dimensions

Minoru Takahashi

It is shown by choosing an appropriate variational wave function that the ground state energy is not affected by the repulsive delta-function potential in two and three dimensional systems. Scattering cross section by the repulsive delta-function potential is shown to be zero.

Resonance scattering from a double δ-function potential

I. Richard Lapidus

The transmission coefficient and total cross section as functions of energy are obtained for scattering of particles by a double δ-function potential in one dimension. This example may be useful for the discussion of resonance scattering in an introductory quantum mechanics course. (AIP)

Carlos R. Handy

The recent Letter by Bender, Berry, and Mandilara (2002, BBM) presents some interesting symmetry arguments which enable one to transform non-hermitian, PT invariant, (complex) polynomial potential hamiltonians, into secular equation representations with real coefficients. This achievement is claimed to ``demistify'' why these systems can admit real and/or complex eigenenergies. Two approximations underly their arguments, and weaken the implied significance of their work.
