Question

spread of gussian wave packet​

Answer 1

❇️$\bold\orange{ANSWER}$❇️

The Gaussian wavepacket only spreads in the free Schrodinger equation. It doesn't spread in the case where you have a harmonic oscillator, and the Gaussian width is equal to that of the ground state wavefunction. For other Gaussians in an oscillator, the width oscillates, growing and shrinking.
