Query: A discrete model of energy-conserved wavefunction collapse   Energy nonconservation is a serious problem of dynamical collapse theories.
In this paper, we propose a discrete model of energy-conserved wavefunction
collapse. It is shown that the model is consistent with existing experiments
and our macroscopic experience.
