WKB / Bohr–Sommerfeld Quantization

This interactive simulator explores WKB / Bohr–Sommerfeld Quantization in Chemistry. 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). Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: For learners comfortable with heavier math or second-level detail. Typical context: Chemistry.

How it works

Semiclassical Bohr–Sommerfeld quantization for an arbitrary 1-D potential V(x). Bisection inside the action integral ∫√(2m(E−V))dx gives the WKB ladder E_n; presets include harmonic, quartic, Morse, double well, asymmetric and square wells (ℏ = m = 1).

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.

Ramsey Fringes (Atomic Clock)

Separated-oscillating-fields sequence π/2 — τ — π/2 with detuning Δ and coherence T₂. Sweep τ or Δ to see P(|1⟩) = ½(1 − cosΔτ · e^{−τ/T₂}) — fringe period 2π/Δ, exponential T₂ envelope; the Bloch sphere animates each stage. Foundational to atomic clocks and Ramsey interferometry.

CHSH Bell Inequality Test

Monte-Carlo of the singlet state |Ψ⁻⟩ at four measurement angles (a, a′, b, b′): the running estimate Ŝ approaches the Tsirelson bound 2√2 ≈ 2.828 at the canonical Bell angles (0°, 90°, 45°, −45°), violating the local-realist limit |S| ≤ 2 — quantum entanglement made statistically visible.

Hong–Ou–Mandel Two-Photon Dip

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.

Kronig–Penney Bands & Brillouin Zone

Periodic δ-comb model of a 1-D crystal: cos(ka) = cos(qa) + (P/qa) sin(qa). Find allowed energy bands and forbidden gaps from the |·|≤1 corridor, then watch each band fold into the first Brillouin zone k ∈ ±π/a. Free-electron parabola overlaid for reference.

2D Box: Eigenstates & Degeneracy

Particle in a 2-D rectangular infinite well: ψ_{n_x,n_y} ∝ sin(n_xπx/L_x)sin(n_yπy/L_y), E ∝ (n_x/L_x)² + (n_y/L_y)². Toggle a square box (L_x = L_y) to expose the (n_x, n_y) ↔ (n_y, n_x) accidental degeneracy and watch the doublets split as the box deforms.
