⚛️ 2D Quantum Wave Packet: Tunnelling and Slit Diffraction

Interactive 2D solution of the time-dependent Schrödinger equation by the split-step Fourier method: launch a wave packet, paint potential walls, and watch tunnelling, single- and double-slit interference, a harmonic well and a circular cavity with a live detector-screen pattern.
