Homework Statement
Say, for example, a wave function is defined as 1/sqrt(2)[ψ(1)+ψ(2)] where ψ are the normalized stationary state energy eigenfunctions of the ISQ.
Now, say I make a measurement of position. What becomes of the wavefunction at a time t>0 after the position measurement (i.e. after it has had time to evolve)?
The Attempt at a Solution
I would assume that the wave function would become a superposition of inifinitely many stationary states, but such that the expectation value of the Hamiltonian (energy) is the same so as to stay in line with the conservation of energy.
