Introduction to The Vortex Atom
2. The Fundamental Unit
The invariant
The program identifies the fundamental irreducible element as a finite string that follows a helical trajectory where linear translation and intrinsic rotation are fluidly interchangeable.
Mechanical refraction
This provides a purely mechanical basis for the refractive index n. In dispersive media, linear action is redistributed into rotational action (Sp-1) allowing the photon to slow down while maintaining frequency and action conservation.

Figure 1. A finite string that follows a helical path with a rake angle π/4 at speed √2c on a notional tube. This produces a Sp-1 rotation at speed c and a linear motion at speed c.

3. Particle Morphology and Momentum Fields

-
Sp-1 (String): Optical SAM. The intrinsic rotation of the string as it takes a helical path.
-
Sp-2 (Poloidal): Optical OAM. The rotation of the Sp-1 axis around a notional tube. This defines rest mass and is constrained to an angular momentum ħ. This rotation generates a magnetic momentum field.
-
Sp-3: (Toroidal): Rotation of the notional tube axis around the toroidal centre. The electron or proton is the Sp-3 structure. This rotation generates the electric momentum field (charge) and (when aligned with a conductor) the macroscopic magnetic field surrounding the wire. The electron is thus a stationary resonant state of toroidal momentum rather than a point-particle in orbit (for example, in a hydrogen atom).
Matter is modelled as a captured helical string closed into a double-loop vortex. The structure possesses three nested degrees of freedom.

4. Fundamental Departures from Maxwell
It should be kept in mind that Maxwell's equations are only macroscopic laws of association. For example, when a current of a certain magnitude flows in a conductor, it is associated through an equation with a magnetic field of a certain strength circulating around it. Maxwell's equations provide no mechanism for what might be happening on a microscopic level. The PTV substructure renders several Maxwellian devices obsolete.
Intrinsic magnetism
Although the PTV model generates a magnetic momentum field from Sp-2 rotation, the observed magnetic field around a current-carrying conductor arises from the electron's Sp-3 field (electric momentum flow). The field does not require the motion of charge to exist; it only requires common toroidal alignment.
Momentum flow v rotation
Magnetic field lines represent a flow of momentum. There is no intrinsic rotational momentum (curl) around a magnetic field line.
Obsolescence of displacement current
Maxwell's ∂D/∂t represented fictitious ether charges and its only utility was to obtain a wave equation. In PTV theory, the rotating light-string provides the wave-nature inherently.
Local field generation
Induction is an internal redistribution of action between Sp-2 and Sp-3 to preserve the Sp-2 action h. A changing magnetic momentum field around a target Sp-2 circuit results in a decrease or increase in Sp-3 (electric) momentum. No electric field is generated ex nihilo in the vacuum

TUTORIAL 1. WHY THIS MODEL?
The three tables below show how accurately the Photonic Toroidal Vortex (PTV) model reproduces experimental measurements of the hydrogen spectrum. The calculations rest on a set of nested vortices denoted as Sp-1 (optical SAM), Sp-2 (optical OAM), and Sp-3 (toroidal rotation). No quantum mechanical wavefunction, no external potential, and no perturbative expansion series have been employed.
Table 1 shows that sub-MHz accuracy can be produced in the hydrogen fine structure without a Coulomb potential generating the energy levels. Instead an internal potential is defined. The hyperfine energies involve the interaction between the electron and nuclear magnetic moments. These are traditionally based on the centroids of the hyperfine levels. In PTV theory, the target is the hyperfine midpoint frequency as being more appropriate for geometrical symmetry. Table 2 compares the experimental hyperfine midpoint frequencies (calculated from Horbatsch and Hessels) with the PTV prediction. Errors are at or below 0.1 MHz across thirty states. For the lowest state of each set, agreement is essentially exact. Table 3 gives the magnitude of the shift each side of the hyperfine mid-point.

TABLE 3. Results for the magnitude of the hydrogen hyperfine shift from the mid-point hyperfine frequency (MHz) for various states using Eq. (35), Paper C. The same shift occurs each side of the mid-point so this is half the usual quoted value. The experimental value from Horbatsch and Hessels is at the top and the PTV value at the bottom. The deviation from experiment is hf-error.
