Quantum mechanics phasing through a wall
WebThrough the wall, we have O ( n) atoms tunneling a macroscopic distance. In order to have quantum tunneling one needs a specific wavefunction which is the solution of the boundary conditions of the problem. Specific means all energies and phases are known. The wall, as a potential, cannot enter into a simple quantum mechanical equation because ... WebThis means there’s a small chance we can find our electron on the other side of the barrier. Or in there, too. Once it’s on the other side, we can say the electron “tunneled through” the …
