🚇 Quantum Tunnelling Wave Packet: Split-Step Schrodinger Solver (2D)

A real time-dependent Schrödinger equation solver: a Gaussian wave packet propagates via the split-step Fourier method and tunnels through a rectangular potential barrier. Adjust barrier height, width and packet energy, and watch measured transmission and reflection probabilities accumulate live.

⚙ Under the hood

A real numerical solution of the time-dependent Schrodinger equation: a Gaussian wave packet propagates via the split-step Fourier method and strikes a rectangular potential barrier. Adjust the barrier height, barrier width and the packet's incoming energy, and watch transmission and reflection probabilities accumulate live, measured directly from absorbing boundaries at each edge of the simulation domain.
