WebA last formulation of the time-dependent Schrödinger equation is the method from unitary evolution. Recall that a unitary operator is one that preserves the norm of a state. To this end, suppose that states evolve in time unitarily so that the total probability of a wavefunction is always one: \[\psi (x,t) = \hat{U} (t) \psi (x,0),\] WebOct 16, 2014 · Next, the watermelon: James Kennedy.
