A Model of Wavefunction Collapse in Discrete Space-Time

Dynamics of a discrete-time plant-herbivore model

Wavefunction Collapse and Conservation Laws

It is emphasized that the collapse postulate of standard quantum theory can violate conservation of energy-momentum and there is no indication from where the energy-momentum comes or to where it goes. Likewise, in the Continuous Spontaneous Localization (CSL) dynamical collapse model, particles gain energy on average. In CSL, the usual Schrödinger dynamics is altered so that a randomly fluctuat...

Can Wavefunction Collapse Conserve Energy?

The answer may be yes. A discrete model of energy-conserved wavefunction collapse is proposed. It is shown that the model is consistent with existing experiments and our macroscopic experience.

Decoherence and Wavefunction Collapse in Quantum Measurements

Examining the notion of wavefunction collapse (WFC) in quantum measurements , which came again to be in question in the recent debate on the quantum Zeno effect, we remark that WFC is realized only through decoherence among branch waves by detection, after a spectral decomposition process from an initial object wavefunction to a superposition of branch waves corresponding to relevant measuremen...

Losing Your Marbles in Wavefunction Collapse Theories

Peter Lewis ([1997]) has recently argued that the wavefunction collapse theory of GRW (Ghirardi, Rimini, and Weber [1986]) can only solve the problem of wavefunction tails at the expense of predicting that arithmetic does not apply to ordinary macroscopic objects. More specifically, Lewis argues that the GRW theory must violate the enumeration principle: that ‘if marble 1 is in the box and marb...
