1) It still is an energy eigenstate, unless I've confused something somewhere. The Hamiltonian applied to Ψ(r, t) should give the same value for E regardless of t.
2) I certainly agree that QM is the basis to everything. However, with the quantum gravity issue, I didn't want to imply it was a grand unified theory to someone who wasn't familiar with QM.
3) I haven't taken a solid state physics course, so I'm afraid I don't know enough to answer that.
