Sequential Stern–Gerlach

Launch Simulator

Two SG devices: P(up on SG₂) = cos²(θ/2) or sin²(θ/2) after |±z⟩ filter.

Anderson Localization (1D Tight-Binding)

Launch Simulator

Random onsite disorder W on a 1-D chain: diagonalize H, plot |ψ|² eigenstates, IPR vs energy, and localization length estimates (RMS and exponential fit).

Quantum Hall Edge States & σ_xy Plateaus

Launch Simulator

Integer QHE: chiral edge channels and skipping orbits in a Hall bar, filled Landau levels vs μ, and quantized Hall conductance plateaus σ_xy = ν_f e²/h.

Wigner Function (Coherent vs Squeezed)

Launch Simulator

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.

WKB / Bohr–Sommerfeld Quantization

Launch Simulator

Semiclassical bound-state energies for arbitrary V(x): harmonic, quartic, Morse, double-well, asymmetric and square wells. Bisection on the action ∫√(2m(E−V))dx = (n+½)πℏ gives the WKB ladder; compare with the exact harmonic ladder ℏω(n+½).

Hong–Ou–Mandel Two-Photon Dip

Launch Simulator

Two indistinguishable photons enter opposite ports of a 50/50 beam splitter and bunch into the same output: coincidence probability P_c(δτ) = ½(1 − V·exp(−(δτ/τ_c)²)) (Gaussian) or Lorentzian. Drag the delay δτ to walk through the dip; live Monte-Carlo converges to the analytic curve. Visibility V = indistinguishability.
