Gray–Scott Patterns
Reaction–diffusion u,v; coral / mitosis / worms / spirals; D_u, D_v, Δt.
Qubit Decoherence: Lindblad / T₁ T₂
Two-level Bloch master equation in the rotating frame with drive Ω, detuning Δ, T₁ relaxation and T₂ transverse decay. The Bloch vector spirals inside the sphere — the geometric picture of decoherence with live populations P(|0⟩), purity Tr ρ², and time traces of u_x, u_y, u_z.
Gaussian Wave Packet
Free spreading: σ(t) from dispersion with ℏ = m = 1; uncertainty intuition.
Orbital Shapes (Schematic)
2D |ψ|² colormap for s-, p-, and d-like angular patterns (pedagogical, not HF).
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.
Bloch Oscillations & Wannier–Stark Ladder
1-D tight-binding electron in uniform field E: semiclassical k(t), Bloch-periodic x(t), and finite-chain Wannier–Stark ladder with spacing ≈ eEa.
