Visualise quantum wavefunctions evolving in real time. A wave packet propagates, tunnels through barriers and reflects — the Schrödinger equation brought to life in interactive simulation.
The time-dependent Schrödinger equation iℏ∂ψ/∂t = Ĥψ is solved numerically. The probability density |ψ|² shows where the particle is likely to be found.
Set up potential barriers and wells. Launch a wave packet and watch it propagate, reflect and tunnel. The probability density evolves according to quantum mechanics.
Quantum tunnelling is exploited in tunnel diodes, scanning tunnelling microscopes and flash memory. The Sun shines because protons tunnel through the Coulomb barrier to fuse — without tunnelling, the Sun would be cold.
