What is Quantum Mechanics: Propagators & Actions about?
1. The propagator for a free particle in momentum space is the Dirac delta function times an exponential term that depends on the momentum and time. 2. A Gaussian position-space wave packet evolves into another Gaussian wave packet where the width and position change with time according to deterministic equations. 3. The propagator for a simple harmonic oscillator depends on the frequencies, masses, and initial and final positions, and involves exponentials of sinusoidal terms.
