SRC as Crystalline Cosmic Fluid

The scalar field φ is a compressible cosmic fluid with self-generated interlocking crystalline order (liquid-crystal / quasicrystal hybrid).

Feature Physical Analogue SRC Implementation
Interlocking lattice Tetrahedral/hexagonal grains that shear but stay locked Topological term **β/2
Force transfer Compression waves → gravity-like pull
Shear waves → EM-like currents
Linearised equations give two sound speeds: cₗ (compression/gravity) and cₜ (shear/light).
Vortices = particles Lattice defects/dislocations (stable due to topology) Hopfion/vortex solutions are defects with winding W.
Damping γ Viscous drag Explicit γ ∂ₜφ term.
Axial flow (expansion) Global shear → cosmic expansion Uniform background flow drives Hubble-like term.

Speed of light: Photons are transverse shear waves → c = cₜ = √β (in natural units where ρ=1). Gravity waves are longitudinal compression at cₗ.

Bottom line: Forces propagate as elastic waves through the interlocking crystal-fluid. Vortices (particles) are stable defects. No action at a distance, no separate dark components.

See notebooks in notebooks/ for quantitative extraction of cₜ, cₗ, vortex statistics, and expansion rate.

SRC as Crystalline Cosmic Fluid

The scalar field φ is interpreted as a compressible cosmic fluid with self-generated interlocking crystalline order (liquid-crystal / quasicrystal hybrid).

Feature Physical analogue SRC implementation
Interlocking lattice Grains that shear but stay locked Term **β/2
Force transfer Compression waves → gravity
Shear waves → light
Linearised equations yield cₗ (gravity-like) and cₜ = √β (light-like)
Particles Topologically stable lattice defects Hopfions / vortices with winding number W
Damping γ Viscous drag Explicit γ ∂ₜφ term
Cosmic expansion Global shear flow Uniform background ∇φ drives Hubble-like term
Speed of light Transverse shear waves c = cₜ = √β (exact in linear regime)

Core idea – All forces propagate as elastic waves through the interlocking crystal-fluid. Particles are stable topological defects. No action-at-a-distance, no separate dark components.

Quantitative Evidence: Emergent Speed of Light

Linearised perturbations show that transverse (shear) modes propagate with exact phase speed cₜ = √β.

  • Method: Exact Fourier spectral propagation (no numerical dispersion).
  • Result (65,384 steps): measured cₜ = 0.01095052 (relative error 0.036% vs theoretical √β = 0.01095445).
  • Figure: See figures/wave_speed_measure.pdf (clean long-time oscillation + ultra-sharp spectral peak).
  • Code: Fully reproducible in scripts/wave_speed_measure.py.

This sub-0.04% agreement confirms that transverse shear waves propagate at precisely √β, identified as the emergent speed of light.

Laboratory & Educational Simulations

These scripts provide simple, standalone demonstrations of key SRC concepts using real-world analogs.

  • scripts/ice_flexo_analog.py
    2D quasi-static simulation of flexoelectricity in a bent water ice slab.
    Reproduces the large measured flexoelectric coefficient (~1.14 nC/m from Wen et al., Nature Physics 2025) using scaled SRC parameters (G_shear, χ-inspired coupling).
    Features temperature-dependent surface enhancement near the 160 K ferroelectric transition.
    Dependencies: numpy, matplotlib
    Run: python scripts/ice_flexo_analog.py
    Example output: outputs/ice_flexo_T200K.png (or similar)
