Are there quantum jumps?

It seems that from the Schrödinger's equations of motion, the wavefunction follows a differential equation which predicts no jumps. So are there quantum jumps?

From thermal phase transition to quantum phase transition

In this video, we review thermal phase transition and explain how quantum phase transition comes about.
