Gray–Scott Patterns
Reaction–diffusion u,v; coral / mitosis / worms / spirals; D_u, D_v, Δt.
Gibbs Free Energy
ΔG = ΔH − TΔS; sign vs spontaneity at constant p,T (no Q or K).
Hückel π-MO (Butadiene & Benzene)
Secular matrix H = αI + βA; eigen-energies and LCAO maps on the π skeleton.
MO Diagram: Homonuclear Diatomics (H₂–O₂)
σ/π ladder with Li–N vs O ordering; bond order from valence MOs; O₂ π* unpaired → paramagnetism.
Wigner Function (Coherent vs Squeezed)
Phase-space quasi-probability W(x, p) for a single-mode Gaussian quantum state: coherent |α⟩, displaced-squeezed D(α)S(ξ)|0⟩, and thermal. The 1σ ellipse rotates by half the squeeze phase θ/2 and shrinks below the vacuum floor along one quadrature — the basic picture of CV quantum optics.
Coherent State |α⟩ in a Harmonic Oscillator
Animated Gaussian wavefunction of a coherent state |α⟩ in a 1-D harmonic well: rigid σ = 1/√2 packet whose centroid traces the classical orbit ⟨x⟩(t) = √2|α|cos(ωt − φ_α). Side-by-side phase space, |ψ(x,t)|², and ⟨x⟩(t) trace.
