| contents | In the hunt for WIMPish dark matter and testing our new theory, we extend the results obtained for the Kepler problem in NQG I and NQG II to the Euler two-centre problem and to other classical Hamiltonian systems with planar periodic orbits. In the first case our results lead to quantum elliptical spirals converging to elliptical orbits where stars and other celestial bodies can form as the corresponding WIMP/molecular clouds condense. The examples inevitably involve elliptic integrals as was the case in our earlier work on equatorial orbits of toy neutron stars (see Ref. [27]). Hence this is the example on which we focus in this work on quantisation. The main part of our analysis which leans heavily on Hamilton-Jacobi theory is applicable to any KLMN integrable planar periodic orbits for Hamiltonian systems. The most useful results on Weierstrass elliptic functions needed in these two works we have summarised with complete proofs in the appendix. This has been one of the most enjoyable parts of this research understanding in more detail the genius of Weierstrass and Jacobi. However we have to say that the beautiful simplicity of the Euler two-centre results herein transcend even this as far as we are concerned. At the end of the paper we see how the Burgers-Zeldovich fluid model relates to our set-up through Nelson's stochastic mechanics. |
