Appendix X — Derivation 24: Full Coherence Kernel and Anisotropic Generalisation

Overview

Previous formulations of PBG used the spherically symmetric kernel:

B(r)=Arekr

derived as the solution to a Helmholtz-type anchoring cost equation in isotropic space.

In real systems, coherence sources are not isotropic—modal clusters like galaxies, atoms, and spin-aligned particles emit structured coherence fields.

This appendix generalises the kernel to:


1. Anchoring Cost in General Form

The anchoring cost functional for a coherence field $$B(x)$$ with modal sources $$S(x)$$ is:

C[B]=(α(B)2+βB2J(x)B(x))d3x

where $$J(x)$$ encodes the anchoring demand from modal sources:

J(x)=S(x)Γ(x,x)d3x

Minimising the cost functional gives:

α2B(x)βB(x)+J(x)=0

Substituting the source integral:

α2B(x)βB(x)+S(x)Γ(x,x)d3x=0

2. Interpreting $$\Gamma(x, x')$$ as a Green's Kernel

We define $$\Gamma(x, x')$$ as the fundamental response kernel of the coherence medium:

(α2β)Γ(x,x)=δ3(xx)

This is the Green’s function of the Helmholtz operator:

Isotropic case:

Γ(|xx|)=14παek|xx||xx|where k=β/α

Generalised form:

If $$S(x)$$ contains angular dependence or structured phase topology, $$\Gamma(x, x')$$ must account for:

We expand $$\Gamma$$ in angular harmonics:

Γ(x,x)=,mΓ(|xx|)Ym(r^)Ym(r^)

This allows non-spherical coherence propagation based on source geometry.


3. Constructing Structured Sources

Let a source mode $$\psi(x) = \rho(x) e^{i \phi(x)}$$ have phase winding or alignment.

Its anchoring emission is not isotropic. For example:

Define:

S(x)=f(x)P(x^)

where $$\mathcal{P}$$ is an angular profile (e.g. Legendre, spherical harmonic), and $$f(x')$$ describes spatial extent.

This source, convolved with $$\Gamma(x, x')$$, yields an anisotropic coherence field.


4. Implications of Anisotropic Kernels

Structured $$\Gamma(x, x')$$ fields lead to:

These effects are fully encoded in the kernel, with no need for force mediation or added fields.


5. Practical Computation

In numerical simulations:

This method handles:


Conclusion

The full coherence kernel $$\Gamma(x, x')$$ is not a free function.
It is the derived Green’s response of a structured modal medium, shaped by geometry, anisotropy, and phase topology of sources.

All lensing, field shaping, and deflection arise from this kernel’s structure.
