Quantum Tunneling Lab

Barrier editor with exact T(E) vs WKB and a schematic wave-packet animation.

About this tool

Quantum Tunneling Lab — rectangular barrier (ħ=m=1). Exact transmission T(E) compared with the WKB estimate e^{−2κa}. Drag V₀, width, and E. Animate a Gaussian packet to see reflected/transmitted amplitudes. Educational.
