Hi .
For a system such as an infinite well or a harmonic oscillator if the energy is measured and it returns a value , say E1 corresponding to the ket | 1 > then this evolves according to exp( -iE1t/ħ) | 1 >.
So this means that for any time >0 a measurement of the system will always give the value E1 ?
If I'm right so far , what does it mean to say the wavefunction evolves according to the Schrodinger equation ? As the system always stays in the state | 1 > ?
Thanks
