§ 0 Unit Ledger (all densities J m⁻³)

symbol rôle SI units note
Φ dimension-less phase 1 —
ψ complex envelope m⁻³ᐟ² $
α spatial stiffness J m⁻¹ fixes G
β quadratic anchoring J m⁻³ sets Yukawa mass
γ temporal inertia J s² m⁻³ fixes c
λ quartic cap J m⁻³ saturation bound
η mass-substrate coupling J kg⁻¹ η=4παG=c2

(Every term in the action density below evaluates to J m⁻³.)


§ 1 Quartic-Anchor Action with Source

S[Φ;ρm]=∫d4x[12γ(∂tΦ)2−12α|∇Φ|2−12βΦ2−λ4Φ4−ηρmΦ]

Helmholtz–Duffing equation

(1.1)γ∂t2Φ−α∇2Φ+βΦ+λΦ3=ηρm.

Static limit (∂tΦ=0):

(1.2)α∇2Φ−βΦ−λΦ3=−ηρm.

§ 2 Kernel & Topological Charge

2.1 Yukawa solution (weak-field, |Φ|≪Φmax)

For a point mass ρm=Mδ3(r) and neglecting the
cubic term:

Φ(r)=Q4παe−krr,k=β/α,Q=ηM=c2M.

2.2 Saturation amplitude

Φmax=β/λ.

Yukawa form valid only while |Φ|≪Φmax.

2.3 Flux quantisation

∮Σ∇Φ⋅dS=2πN,N∈Z⟹Q=2παkN.

Integer-charge kernel:

ΦN(r)=Ne−krkr,|ΦN|≪Φmax.

§ 3 Universal Force Law

World-line action for a point mode of inertial mass m:

Smode=∫dt[12mr˙2+mc2Φ(r)].

Euler–Lagrange:

mr¨=−mc2∇Φ.

For kr≪1 and N=1:

|F|=GMmr2,G=c44πα.

§ 4 Slow-Envelope (Schrödinger) Limit

Write ψ=φe−iωt with ω≫φ˙.

i∂tφ=−α2γω∇2φ+β−γω22γωφ.

Identify

m=ℏ2γωα,Vbias=mc2Φext(x),

to obtain the ordinary Schrödinger equation.
