| What exactly is a stationary state? They talk a little bit about it on page 26 of Griffiths...Is it just every solution of the time independent solution to the Sch. Eqn.? | What exactly is a stationary state? They talk a little bit about it on page 26 of Griffiths...Is it just every solution of the time independent solution to the Sch. Eqn.? |

| A stationary state is synonymous with Eigen state. Basically, a state that doesn't radiate energy. The probability density of these states has no time dependence. Small perturbations can be ignored. Hence... stationary... in time. It should be noted that the only true stationary state is the ground state. With enough perturbation ... a stationary state can be made un-stationary. yes? Like granny in her rocker. Small movement doesn't tip her out... but come hurricane season... she's not really stationary till she's on the ground. | A stationary state is synonymous with Eigen state.
