§13.28(i) Exact Solutions of the Wave Equation

The reduced wave equation 2w=k2w in paraboloidal coordinates, x=2ξηcosϕ, y=2ξηsinϕ, z=ξη, can be solved via separation of variables w=f1(ξ)f2(η)eipϕ, where

13.28.1 f1(ξ) =ξ12Vκ,12p(1)(2ikξ),
f2(η) =η12Vκ,12p(2)(2ikη),

and Vκ,μ(j)(z), j=1,2, denotes any pair of solutions of Whittaker’s equation (13.14.1). See Hochstadt (1971, Chapter 7).

For potentials in quantum mechanics that are solvable in terms of confluent hypergeometric functions see Negro et al. (2000).

§13.28(ii) Coulomb Functions

See Chapter 33.

§13.28(iii) Other Applications

For dynamics of many-body systems see Meden and Schönhammer (1992); for tomography see D’Ariano et al. (1994); for generalized coherent states see Barut and Girardello (1971); for relativistic cosmology see Crisóstomo et al. (2004).
