Features

• Photon Dark Photon Fuzzy Dark Matter (FDM) Entanglement Derivation formulas and steps, consolidated:
• 1. Relativistic Foundation Action: S=∫d^4 x√(-g) [ 1/2 g^μν ∂_μ ϕ∂_ν ϕⓜ-1/2 m^2 ϕ^2 ]+S_"gravity" Klein-Gordon Equation: □ϕ+m^2 ϕ=0,□=g^μν ∇_μ ∇_ν
• 2. Non-Relativistic Limit Field decomposition: ϕ(x,t)=1/√2m [ψ(x,t)e^(-imt)+ψ^* (x,t)e^imt ] Schrödinger equation: i∂_t ψ=-1/2m ∇^2 ψ+mΦψ
• 3. Self-Gravity Closure Poisson equation: ∇^2 Φ=4πGρ=4πG∣ψ∣^2 Full Schrödinger-Poisson system (ℏ=1): i∂_t ψ=-1/2m ∇^2 ψ+Φψ,∇^2 Φ=4πG∣ψ∣^2
• 4. Two-Field FDM (Light-Dark Duality) Combined wavefunction: ψ=ψ_t+ψ_d e^iΔϕ Coupled evolution (weak mixing ε≪1): i∂_t ψ_t=-1/(2m_t ) ∇^2 ψ_t+(Φ_t+ϵΦ_d)ψ_t i∂_t ψ_d=-1/(2m_d ) ∇^2 ψ_d+(Φ_d+ϵΦ_t)ψ_d Interference density: ρ=∣ψ∣^2=∣ψ_t ∣^2+∣ψ_d ∣^2+2R(ψ_t^* ψ_d e^iΔϕ) Fringe spacing (plane wave approximation): λ=2π/(∣Δk∣)≈h/mv where vis relative velocity between sectors.
• 5. Solitonic Solutions Stationary ansatz: ψ=√(ρ(r)) e^(-iμt) Stationary equations: μ√ρ=-1/2m ∇^2 √ρ+Φ√ρ,∇^2 Φ=4πGρ Ground state core density scaling: ρ_c∝m^2/G ________________________________________ Key Physical Insights: FDM mass scale: m∼10^(-22) " eV" gives de Broglie wavelength comparable to dwarf galaxies (~kpc) Wave behavior: Schrödinger-Poisson system describes coherent, self-gravitating Bose condensate
• Two-field interference: Creates observable density fringes with spacing λ ∝ 1/(mΔv) Solitonic cores: Naturally form stable, non-fragmenting structures (explains dark matter cores in galaxies) Experimental relevance: For comet-scale observations (like 3I/ATLAS), fringe spacing can be tuned to match observed angular offsets (~arcseconds)
• Applications: Galactic scale: Solves cusp-core problem in dwarf galaxies Laboratory/SS scale: Interference patterns could manifest as periodic forces or density modulations Dark photon connection: Two-field FDM provides framework for light-dark sector interactions This derivation establishes FDM as a viable wave-based dark matter candidate with testable phenomenological consequences across scales.
